So the codes with verbiage.
P1120 Throttle Position Sensor "A" Circuit
P1221 Throttle Position Sensor "A/B" Range/Performance
P1515 Command vs. Actual Throttle Position Correlation (PCM) Error
P1516 Command vs. Actual Throttle Position Correlation (TAC Module) Error
I replaced the TPS about a year ago trying to fix the problem and it didn't do anything. I am looking at used TAC modules for $160 or so but don't want to buy it if it isn't the problem. I am not well-versed in wiring but I own a multimeter. Would just need a small amount of coaching such as "Set it to DC 20v and put probes here and here".
I am hoping that this symphony of codes will point to something specific for a trained eye! Any thoughts? Next steps of troubleshooting? Thank you for your help!
have the same problem?
