I know you're a very busy man, but I look forward for every new upload of your wisdom.

Watching a professional mechanic troubleshoot live was actually really helpful π
-
Class is in session, I'm taking notes for the test. I always enjoy stopping by the shop!
-
Excellent troubleshooting. I liked how you went through what also worked and moved on to checking the TPS switch.
-
Thank you for this video! Very interesting! If the "store" had this in stock, it must be a common failure on these cars.
-
I love learning new stuff like this! Keep it up.
-
Good to see you are back.
-
Interesting i was just watching videos about power and ground side switches. Cool to see how to use logic when not having a diagram and scope in hand. Thank you sir.
-
Excellent diagnostic tutorial! Thank you!
-
Love that u did this live. We learned together π
-
I like that you get it fixed right π I would have done two things before replacing the switch and if it mostly fixed it, may have left it at that.. leading to a bad computer I guess lol First would have been cleaning the throttle body. Second would have been cleaning the contacts of the sensor and disassemble it if able for further cleaning and inspection. Then while in there I'd probably clean the maf or map, anything I might have taken apart to get the TB off for a full cleaning. Lol
-
This was awesome. Excellent explanation. Would love to see this for other sensors, esp. 02 sensor or nox sensor for diesel.
-
The last time I wacked my sensor it was sore for two or three days. Eventually everything started working well again. Seriously though great info man!
-
Thank you! Great explanation.
-
You are a God because you know what you didn't even know I had this problem at the moment of trying to identify without that diagnostic tool that you were talking about but yes thank you so much I do have a multimeter
-
very good explanation , thanks and good timing for me because I am trying to diagnose a problem with my 2000 mazda .
-
Excellent talk through thanks

I had a 91 Camaro 3.1 L engine that puked the TPS sensor at 93K miles and it had all the symptoms with erratic idle and was easily validated. Also, given the amount of miles on the odometer, it is very common that a good many vehicles for the mileage of 90K miles or better for the TPS to fail. Also, knowing that my Mom had the ECU replaced by the dealer already for another problem all together previously. Upon replacing the TPS sensor, I also took the liberty of cleaning the IAC Valve pintle and also inside the IAC port housing for good measure! I also did cleaning of the internal throttle valve body and the mass airflow sensor as a scheduled service!

Great stuff !

Great tip with the screwdriver mimicing the bumps and vibrations of the road and engine. For the adjusting of the TPS, how does that work? Is there just an allowable tolerance spec you put it in and mount it?? π€
