Pull and post ALL the codes including the H or C or HC that follows each 5 character code. List the codes under the sensor that they show with. ie 10 - PCM or 28 - TCS or 40 - BCM ..... etc ..... If any sensor has NO COMM next to it post that also.

If you have never pulled codes before here is how:

Codes that relate to Traction Control will be listed under 28 - TCS.
Hello there thanks for your time, ive cleared other codes prior to these coming up again yesterday. The codes that come up were 10-pcm , P1120h, P1122h, P1221h.
28-tcs, C1278h. Like I said there were others but I cleared them. I tried to clear these that I have listed but they keep coming back so we left the car home cause of the reduced power then come back a few hours later and managed to clear them and have them stay cleared. I'm not sure what to do, I just fitted a new optima battery in January this year and haven't driven it since maybe a coincidence not sure cheers Colin

The ThrottlePosition sensor consists of two individual position sensor circuits. It seems both sensors have problems.

Check the wiring and plugs on the TP .

I attach both troubleshootings procedures ( P1120 and P1220 )
