Wow that's so amazing! God is so good!!

Just gonna take a wild guess, and try to translate what @jamesdewer was asking: Was the problem because of the sensor, or was it because of wiring (short, open, loose connector, corrosion, etc)? And here's my take on why I assume Rob is correct for calling the shot on it being the sensor: Although he didn't go into (at least in this video) testing the integrity of the wiring harness, from the sensor to the computer, I'm pretty sure he would've actually done that (given that it's literally his specialty, dealing with electrical issues, and with his simple of a test it is). To test the wires, there's 2 simple methods: 1) disconnect the battery negative, unplug the sensor and the corresponding ECU connector(s), back probe a jumper wire between all terminals at the sensor (imagine snipping the connector off, stripping the wires, and wire nutting them all together... Minus the destructiveness 😅), and test for continuity and resistance at the ECU connector, remove the jumper wire, and test continuity again (keep in mind, not every car's ECU separates the grounds from the sensor grounds completely.. some older ones, especially, have a sensor ground location near the ECU, while the other grounds are on the head/block and frame. In that case the ECU sees and anticipates the slight difference in voltage... But, most cars ECU's DO have their sensor grounds DIRECTLY to the ECU, and the ECU shunts it however it sees fit. Basically, it doesn't want to see -12vDC. Sometimes they don't even want to see 0vDC! It possibly could want to see +1.5vDC on the sensor grounds.. the purpose of this, is that this regulated "ground" is very constant, compared to the fluctuating drops and spikes seen from all other grounds. The ECU compares the signal voltage ONLY to the sensor ground, so that it has a reliable (relatively constant) reference point to see the voltage difference... My point being, there's a chance that, without the jumper wire installed, you may OR may not have continuity between the ground lead and the sensor ground lead... Ideally, you would NOT see continuity). 2) disconnect the sensor connector and corresponding ECU connector, use a long length of wire to probe the sensor harness connector, bring the other end of the wire over by the ECU connector, and test for continuity.. repeat for each lead. The fact that the sensor will eventually warm up and function properly (throwing a code, most likely, that it took way too long for what the ECU expects), but not up to the correct temperature quick enough, SCREAMS the heater is blown... And although testing the wire integrity is a MUST, before throwing parts at a car, it's EXTREMELY likely to be the heater. The reasoning behind this, is that the heating element expands when operating (hot) and contracts when it's off (cold), which is basically bending a very fine metal back and forth every time the car turns on, then turns off.. eventually that metal will snap... Imagine a filament in an incandescent light bulb. I love when I stumble around back to Rob's videos. I usually already know exactly where he's going with his diagnosis, but (regardless of his videography and editing skills... Lol mine would be MUCH worse) he reminds me of how I need to explain myself in great detail, to friends and customers, in a way that I know for a FACT that they understand what/why/how I do what I do, or that when they don't understand, I need to slow down, back up, give examples in a way that works for them (for instance, I have to relate car stuff, to sewing machines and cooking recipes, when I'm talking to my mom 😂). He's a GREAT teacher! So much so, that he reminds me how I need to relearn the fact that half my job is explaining myself, to a curious person.... AKA teaching! Another thing that makes his history and schooling worthy of the title he has (a Master) is, that teachers can learn from masters how to teach, not just to remind them about what to teach. Another amazing person (I think Rob actually said he knows this guy, in another video, too) is Paul Danner, from @ScannerDanner. That guy is a Master, also, and it blows my mind how active he is in his field.. even as far as responding to his fans! Paul is a legend! Rob has me hooked on his stuff sometimes, because I SERIOUSLY want to buy that MT2500 for my 92 Hardbody and 95 Pathfinder lol, and when I'm doing work on em, I always revert back to Rob, to keep myself from going down those complicated paths by accident.

I have an issue with mine not idling down after the start. It fires right up but doesn't idle down. Any sugestions?

Ive had my head gaskets fixed, the thermostat, the transmission cooler, and now the head gasket sealed n its still overheating on a 2015 Mitsubishi outlander sports 😡

Whuz it the sensor side or the signal?

Wuz it the senser ur the wirin

Quick question. I have the same stock Datsun truck, but it is a 1982. It won't pass smog because it is running lean. We tried to clean the carb but that did not quick do it. Any advice?

Is that a 2.5T motor ? Thanks

Leaking a Dodge nitro 2007 can't find the league for the motor is running from the right leaks when it gets hot I looked and I can't find the leak

I have a Dodge nitro can find

Brilliant, Dodge built a car around a heater core.

we had these at an AMOCO garage were I worked from 1995-2002 when the owner closed. He had two of these machines.

I live in Illinois and no emissions and inspections thank g\od

Great video. Got a lot to check now 😅

What was the issue

How did he hook up the test kit 😳

Yo dude open your mouth and speak louder we can't hear you retard

How can i find your location of your Shop?

What Days and hours do you work? I have 2005 Mini Cooper R50 having some problems and can't seem to get them completely figured out. 😕

👍

Did you find the cause? Post another vid of the fix?

Not true you don’t have to take the alternator out to test the wires

I have a mitsubishi Outlander 2007 v6 about 180k miles. My new engine got overheated because the radiator pipe got diconnected whilst i was driving. That overheating had me changing the top gasket, top cylinder and other things but its still yet to start or come back working. Now it is not starting and I have been on changing battery and even tried changing MAF sensor but still not working yet. Please help with any ideas. thank you.

Please tell me your shop is in Northern Va......I would love to have my truck treated like that.

wow great work and loved how you sold the job as hey we are suspecting this but to gain access to to complete testing here the MAX price you may see

Guess it's time to sell....

I just noticed the header. I could not install those when in CA. Mine was bone stock. 250k miles on original cat, still passed smog.

My wife and I had 2 85 720s in California. I keep mine 10 years! I had to convert to fuel injection since the carbs would warp.

U don't have to take it out to check plug terminals....I did one today and could just reach down and unplug it....just being honest...I get what your saying but can access plug with ease

I Hope you are still active and help me. My just bought Nitro smells bad when I Turn an AC. So i wann to usw the Liqui Moly AC cleaner. Where would be the best place to spray and reach the Core? Would you just check out the Short Liqui Moly video to help? :) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QDj889vxrL0.html

Can you please do some scope work with autel? I just got the 919 and I'm nervous about using my scope and no one at my shop uses a scope

Where are you located?

I need your help I have 04 Nissan Titan none of my lights on the back worked but I disconnect harness from behind right side door and fixed it so I thought all my lights now work except the brake light I've checked all fuses and relays and the turn signal use the same bulb as the brake. Can you please help me

Worked! Why did this take over a year to find!

I have the same exact problem, only right blinker. Hope this works!

Never mentioned the estimate... How much should this cost?

Oh, I have a 2006 XC90. Can we be friends?

thanks I have had a problem for three years with my trailer lights to find that fuse link awsome

Very informative msg

I tried to jump start relay pin30 and 87a but now wont even click it there a fusible link on the harness I have 2006 qx56

What's the t/f fuse

After all of that, the customer probably said just do the oil change

Thank you so much for this video. I kept trying to figure out why my left signal wouldn't work once I plugged my trailer I'm. I have 2004 nissan titan I'm headed to go pick up my brand new trailer thanks you I won't have a problem with my lights. Thanks

Why are they still testing emissions on a 25+ year old car in Oregon? Cars that old would be exempt from emissions where I live.

Dr rob where are you located

I have a 85 nissan 720 and was wondering how do you check if the computer is communicating with the carb??

Looks like he doesn't answer anyone.

Part 2?

I have a ? We're can I find the fuse from my windshield on a 2006 Nissan tittan

Hey man I have the same vehicle it over heats when the ac is on, when it’s idling longer than five minutes, when I’m going up hills I just spent 1400 on getting the crankshaft an sensor replaced with new belt an fuel pump idk what to do
