Hi guys,

I am getting a P0122 - Thottle position Sensor Circuit low input CEL, and i cannot clear the code... keeps coming back

The car idles perfectly, and runs perfectly.

I know you can disable some codes through the ECU Periphery bits, but I haven't found one for the P0121 and P0122 codes.

Can anyone chime in on this??, anything I can change in the ROM to get rid of this CEL?

Again, the car is running perfectly.

Thank you!

means you have less than 5v on tps easiest way is to fix the prob

I have an OBD2 reader, and it is able to read TPS, RPM, etc,

With the car OFF, ignition ON, the OBD2 scanner is reading the Absolute Throttle Position at 0.

When I go WOT, i get to 99.22
It seems like it is calibrated well, and responds to pedal movement well :/

Mitsulogger 2.0 fails to detect my tactrix 2.0
Any help?

Thanks

Update guys:

I was testing the TPS, and at WOT I am getting 4.7v, and without touching the pedal, I am getting 0.2V, which is low. At idle the TPS should be reading about 0.5V right?

Going to adjust it now.

0.68 to 0.72v

Did it fix the problem? I get the P0122 on random almost everytime even after clearing the code. I was wondering how you get the proper voltage when adjusting the TPS.

Update:

Fixed the code. I had a lot of trouble testing the actual TPS. I did not want to poke a hole in the middle wire that was sending the voltage, so I disconnected it and connected the sensor and plug with 2 small wires, and my volt meter in the middle..
Was getting 5V constant, then 0, and connection was not good....

Scrapped that idea and then just plugged in my OBD2 reader, (reads the TPS), so I just rotated the TPS around until it was at %10 throttle at idle. Cleared the code and it never came back.

proper job somewhere between 10 to 14% is usually ok if it doesnt hit 100% fully open dont worry about it
