P1121 - Accelerator Pedal Position Sensor Range/Performance Problem


Can you give me any ideas what to do to correct my problem? I have no accel. from 0 to 3/4 gas pedal. It is fine until the engine reaches operating tempt.I’ve replaced the TPS switch.Thanks, Bob

It’s obvious that you didn’t go to the link that BarryNNJ showed you. It shows what other people have done who had this problem. If you read down, you’ll see that the tps (throttle position sensor) is NOT the problem.
