My max has about 75K--lots of city driving...about 2 weeks ago the CEL came on, and I pulled the codes, and reset without doing anything--and the codes came back--same codes:

1206- Throttle Body Sensor (Automatic Transmission)
1105 - improper shifting to 3rd gear (A/T)
0304 - knock sensor
0403 - Throttle Position Sensor
0203 - Closed Throttle Position Switch

questions: any one else out there had the same problem...was it just the TPS gone bad, or both the Knock Sensor?

Is the 0203 related to the TPS sensor or with the throttle body itself not opening?

And does the TPS in any way affect the automatic shifting of 3rd gear?

For the time being I reset the ECU to see if the error codes would return...looks like I may need a new TPS?

Any help or comments would be most appreciated.

thanks--
