91 K1500 TPS problem Sign In

I have a 91 Chevy K1500 Pickup that starts and dies, then surges when it does start. It's showing code 22 Throttle Position Sensor is too low. I replaced the TPS but still getting the same code. Novice shade tree mechanic here.. any help/ suggestions appreciated. Thanks

Which engine? You need to measure the TPS voltage using a volt meter or scope with the ignition on at the signal wire at the PCM's connector C pin 13 dark blue. You should also monitor TPS voltage using an enhanced or factory scan tool. You need to confirm if the TPS signal is reaching the PCM or not.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
