Evo 9 p0120
 

Good day,
posting on behalf of a friend as he doesnt have access to internet at the moment, he has an evo 9 that gave him P0120 TPS circuit and iv helped him check on the connector for the 5v supply which is there, and then adjust to max position on Tps it only gets 0.47v at idle or just on 9%, the car goes ok til part throttle then jerks and bucks til you give more throttle and its fine. What could the problem be, could it be the TPS itself? On evoscan data the TPS seems to spike now and then??

please help!!
thanks

Your friend needs a new TPS. Spiking is caused by a worn resistive track inside the device and is not repairable.
