Chrysler Hemi 5.7 Oil Pressure Sensor/Switch Replacement 

First, hats off to DavidJ for a fine video. Second, I would like to buy a "virtual beer" for all of those who were able to remove/replace this without removing the alternator. I removed the three alt bolts and pushed it out of the way, and was able to complete the job. Total time: 1.25 hours.

I was able to get the sensor pigtail disconnected without removing the alternator by carefully sliding a small screwdriver under the plastic clip, pressing up and gently pulling on the wires. Saved me hours of work removing the alternator.

I've done this twice on two cars and have found that a strategically placed screwdriver to break the electrical portion off the sensor makes removal easy. (No matter what position that red locking clip is in.) The sensor is then easy to remove and replace without having to take off the alternator. I can change the part in less than 15 Min., although I hope not to have to.

Really appreciate your step by step install video and Yes. I had to remove or at least disconnect my alternator as well. Some do some don’t. All depends on how that plug is originally oriented. Took about 4 hours with a quick run to the parts store to grab an extension for the New Sensor. Finally done. And best part. No MORE CHECK ENGINE LIGHT!!!!! Thanks Again 🙌🏾😁🙌🏾😁🙌🏾😁

Thanks Brother, super helpful and detailed video. 2014 Chrysler 300S... Tried dislodging the "Devil Clip" without removing the alternator, no bueno/ waste of time. Ended up loosing all three bolts from the alternator, left one of the bottom bolts still attached and just tilting the alternator gave plenty of room. The alternator bolt where David used the combo 4X4&Jack to loosen it. You can actually put your wrench on the bolt and then pull from above with plenty of room and leverage (took me awhile to figure that out).

There is a trick to this. Im not recommending it but if you're a big guy like me who cant move around or a young person without jack stands or maybe its just too hot or cold outside, heres what you do. Or maybe you just dont want to remove those long bolts of the alternator. You can do this is 20 minutes. Take the lid for the air box off, you dont even need to dc the sensor, just the hose on the top of the filter box. let all that rest atop the engine cover. Get a 3/4 wratchet to pull back the belt tensioner, seperate the belt off the alternator pully. Now you want to get an idea of that sensor, Put your index finger on top of that sensor and feel for that red sliding clip. There is a empty space below that sliding clip between it and the sensor itself, similar to the ecm connector to top left. Now, Its a tight fit, you need skinny long fingers, not sausage hands to feet around. Once you figure out where that space is, Slide the screw driver in that empty space and push down gently and break that top red sliding clip off. Dont worry, it'll still literally clip back into place back in and hold tightly , it just wont have that the sliding clip on the top anymore. If you want to try and screw with that clip you'll be there all day. Once you do this gently work that sensor around. These things get hot overtime but eventually you'll feel a slight amount of play and it should release just fine if pull straight out. Dont pull on the wires to get this thing out, pull on the plastic connector itself. Alright so after that, like he said, oily wires, connector, clean that off. When you put it back in, its a pain in the ass. Again, put your index finger where your sensor should go, get a feel and attach a swivel/ short extension to the end of your long socket to give you more grip, baby it in. You only want this thing gently snug. Snap the connector back on, start it up, might have to drive in for a min to get normal pressure readings. If you by chance happen to buy a cheap ebay or amazon sensor like i did and your realize there is no way your socket can fit it like the oem one does, put a 22mm 12 point around the male sensor connector, then swivel/ short extension. Once you get it in, turn and baby it in slowly then tighten until nicely snug. Clip the connector back in and wah lah. And there you have it, no alternator removal.

This shit took me 3 hours in an autozone parking lot… had me personally threatening the engineers

Chrysler built these cars so F-ing weird unbelievable how far they went to make sure most people couldn't do self repairs. Thanks Chrysler ! Good vid Sir Thank you.

It can be done without taking out the alternator or removing the bolts....I know because I just finished replacing mine. But it will take a lot of patience and time...and a little luck. The hardest part of the job is getting the connector off of the sensor because it has a clip that must be slid to the side before you can depress the tab and pull it off. I admit it took me over an hour using a small screw driver and some mirrors to undo the clip, but getting at the alternator bolts is a PITA too so I guess six of one and I choose working on getting the clip moved. Once you do that and baring you have the right size socket with the correct depth barrel, it's easy peasy after that.

I just changed this on an srt8. Didn't take off the alternator. Just removed the belt and popped the red clip with a small screwdriver. Bit of a job to get fingers in the space.

This was my very first DIY car fix. It was frustrating as hell but I got the god damn job done!

Funny thing is he got under the car to loosen the alternator bolt and didn’t realize he could remove the connector and sensor while he was down there🤣🤣🤣

I ended up not having to do any of this extra work. Loosened serpentine belt, popped the red clip with a flathead screwdriver, swapped sensor and oriented so clip was on top for future access.

Almost certain they have gorillas install the alternator bolts at the factory 😂

Thank you so much for this. The jack and block trick saved me a lot of time. On the connector, i had to push the red tab down away from the engine. I guess it depends on who installed it. But for reference for others the connector is just like that one on the EGR in the example, so picture that upside down and move it appropriately. I had better luck getting moving the tab from underneath the car.

I did it the easier way by just removing the air intake and belt, getting a feel for where the clip was and removing it. At first I couldn’t feel the red clip, and after a while I decided to just pull on the clip and it slipped right off. The red clip was broken off. I assume it was broken due to the fact that it is a rebuilt engine. But anyways I’m just happy to have replaced the sensor because after a few months of having the check engine light on, my car was beginning to shut itself off randomly and I assume it was due to the bad sensor.

You know you can just take it out from under the car without removing other parts right?

HE ALSO MENTIONED IN THE VIDEO THAT THERE WAS A MINOR LEAK FROM SENSOR ONTO ALTERNATOR MOUNT! MY SENSOR WAS MAKING PUDDLES!

Good job on taking that alternator off. It sucked for me putting it back inn

How can I tell the difference between the pressure one and tempature ... The pressure one is higher correct. And could this be part of the problem I have code 0520 and 0522 which is wrong oil type and low circuit or oil pressure etc. I replaced with Mopar but code came back

Would it have been easier to just remove the edge valve and tube??

10:35 had me in tears 🤣😭

I have a 2008 Magnum 5.7L same motor as you, but my OPS is closer to the right firewall in front of the front passenger.

I changed mine on a 480 short block without moving the alternator

Lucky for me mine didn't have the red tab... Your vid still helped so thanks

If this sensor were to leak would it drip down to the corner of the oil pan

I just did one of these. Funny it pops up in my feed

Do you have to drain the engine oil to do this?

Really, try this at your own risk. Yep, and clean the connection.

I jist went through wheel well under the car and loosend it from oul filter housing took 20 min to replace max

Hello since your oil pressure was due for a chance was your dash showing the red oil light at idle? Mine shows up at low idle and once I accelerate it takes off, my check engine light came on first & then after about 10 min of driving as soon as I release the gas the light comes on, and I give it gas it comes off

Thank you for that video, I have to replace that sensor too and now I see what and how to do it.

Thanks for the helping tips, You have gain a new subscriber.

I know that is videos is for a 5.7 but in my 2012 300 the location is at the top of the motor towards the back is that the same switch but just a different location for the 5.7?

very good video, one more question: in the video shows another sensor, besides. in the same base of the oil filter. and smaller than the other one that you replace. you know what is it?. appreciate your help.

Yeah I had to buy another oil pressure sensor because the aftermarket one gave me that code again. I guess you have to buy Mopar or it will complain about it 🙄. Here we go again 😒.

Great vid! After switching the red locking tab over can you just pull the connector off or is there something holding it in place?

Does this cause low oil pressure at idle or could low pressure be triggering a faulty switch code

I have oil pressure low changed it with 3 aftermarket and 1 from dealership but oil pressure still low any ideas

Just had the same thing happen on my 5.7 charger. Do you know if it's located on the same spot for the 5.7 Chargers

Nice vid ! What part nbr for oil switch for srt8 charger 6.4? Or is same switch for 5,7 nd 6,4 hemi? Thnx

I wonder what's the sensor called that's located an inch above the oil filter?

Why’d you change it? My oil light keeps coming on and off n my 07 charger rt?

Was your car able to start prior having the code before you changed it

Hi can you drive the car if it has that code? I want to buy a 06 dodge charger hemi but guy said it has a code for oil pressure sensor. Can u buy it and drive it back home to have it fixed?

Did you have any oil leaks right after you engine light came on for the oil pressure switch?

Cool music, great job.

Man great video!!! I am having a hard time taking the sensor housing off. I don't wanna break it(frustration is pushing me there)...I'll be happy if I can go buy a tool to make this come of I will,.. If you have any extra tips on it would greatly appreciate it 😊. Thanks in advance

mine is Dodge Charger RT 2010 Are they located on the same direction

nice detailed vid 👍

Kinda off subject but has anyone had the sensor fail repeatedly? Last one only made it 6 weeks?

Very detailed video! Thank you!

Nice Job. One question. Either those alternator bolts were SUPER tight, or you don't have much strength as needed without using a pipe to act as more leverage?

That's funny mines not there its blocked off, however the oil filter has one is that the one I need to replace?

@DavidJWarEagle do you know if 6.1l srt8 is located in same area?

Does the oil pressure sensor have anything to do with a cylinder 3 misfire

Helpp, i took it to the mechanic to get replaced and the check engine light came kn for the same code after i replaced it

What year is ur car I have an 06 Dodge charger Daytona rt I got the part number from the video just trying to make sure it's for my year

How did u get the fault code to show on the dash ?

How much would the dealership charge for this job

good mechanic dont have to remove alternator to replace sensor or go through back seat to reconnect battery if he closes trunk while disconnected

Thanks

Good video, thank you.

I had to drop the alt

Does anybody know the Threadsize of this Pressure Switch ?

I got a 2006 Ram 1500 5.7. Does this make your car not start?

is it same for 06 dodge charger rt location of sensor etc???

what size socket is needed?

why did you need to change that sensor?

Should of changed that belt to while you were at it lol

May I ask where did you get the part from?

Voice is a little low

I changed mine, now I'm getting a different code telling me the sensor pressure or whatever voltage is low po522, never buying me another american car.

Thank you!

I did this last year from the bottom of the truck, now I have the code again, 520 .truck will not start smh

Found out u dnt have to do all that knuckle busting moans to replace tge sensor!!! Best easy way is buy the socket for it place it under alternator nd loosen it OUT nd screw in the new sensor 30 min job took for me to change it !! Lol

I assume everyone making vids on here has superman hearing do something about your audio. Strange music way too loud. The thumbs down for poor audio not content..

What year is the car?? Is it the same for a 2012 ram with the 5.7???
