Code 22 came up today and my car won't stay running without me giving it gas. The TPS is brand new and adjusted and the trouble codes have been reset but the code comes back up when i start the car. What should i do now?

 

Low voltage from the TPS (Code 22) can be caused by more than a defective TPS. Instead of replacing the TPS, you should check the voltage at the TPS connector. The 'A' terminal should be ECM ground, The 'C' terminal should have a constant +5VDC. The center terminal ('B') is the signal from the TPS to the ECM. and is what you adjust be altering the position of the TPS. If the +5VDC and ground are not connected, you'll get the 22 error.

 

how do i check these wires. One other question... On the DVM do i use AC or DC?

 

dc

ac is for in the house only( alternating current)

dc is direct current (battery)

 

where are the other connections for the TPS that i can check other than the one on the TPS. I checked the ground and the constant 5V and they are OK. The B terminal will only read up to like 2.1 at WOT where can i trace this back to find the problem?
