I've had a hard starting problem on my 2007 Jeep Liberty 3.7L engine for over a year and your video led me to the solution. I have replaced the fuel pump, installed a TIPM by-pass fuel pump relay kit, replaced the spark plugs, purge valve, and leak detection pump - and still no fix. Guess what? The problem was a dirty Air Charge Temp Sensor (It's similar to MAF but Jeep uses a different name and measures air density (pressure, temperature, and humidity) rather than mass air flow. I was able to fix my problem with a can of spray sensor cleaner. The average person will not see a problem because the carbon buildup on the heated wires look like a factory black coating over the wires. The problem is hidden in PLAIN SIGHT. Your video sensitize viewers on what to look out for to find the problem. Hey thanks for the information and saving me $100's in auto repairs. Great video!
Thanks for help with this matter. I need to do this ASAP on my 2018 Jeep Wrangler Unlimited JK 4 cylinder engine. I have been trying to find my MAF sensor and I was unable to find it. I was looking for a bigger model like on my truck and this one on my wife’s jeep is very small.
Thanks. I was thinking I had to remove the motor assb . To get to the sensor. You saved me a bunch of time. So easy there’s no excuse to not doing it often.
That's not the MAF sensor. It's the intake air temp sensor. Jeep Wranglers don't have a MAF sensor. Jeep Wranglers have a MAP sensor which is located on the top driver side of the the intake manifold and can be exchanged literally in the parking lot of wherever you buy the sensor. You don't need tools either.
@@bigfan1364 Hey, Genius, the MAP sensor has a bayonet lock - it's literally 1/4 inch turn without any tools - unless you label your thumb nail to get the cable harness off a tool. No need to take anything off the throttle body or the airbox. Don't believe me? Here you go: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-psEHiTMPVLA.html
@@briangong007 It could. I've had a MAP sensor that didn't fail entirely but simply gave wrong values within the allowed range. That caused the engine to run lean which leads to misfires. A few misfires won't trigger a CEL, the computer simply tries to compensate with fuel trim etc. So your vehicle can run poorly with some hesitation without a CEL or a code. Eventually that will happen though when the sensor fails or things get out of range far enough for the computer trigger a code.So when in doubt, it's a $20 sensor at any parts store and it's switched out in a minute without tools.
Nice video, well explained, and you talk clearly and without shouting! Thanks for that! :) Do you recommend any particular catch-can? I will install one in my Jeep JK 2016 😀
Would have been nice if you showed how you got it back in. That matters. I can't get mine back in. I can see there's shapes that one up. I line them up but still doesn't want to go in
Nothing like calling yourself a “garage” RU-vid channel and putting up a video calling an air temp sensor a (MAF) mass air flow sensor. Also... nothing will happen if you move your throttle blade inside the throttle body. Actually after watching more I can’t even comment on all the misinformation made in this video.
