ISSUE
Some vehicles built 11/29/2004 and prior may exhibit the wrench light on with both P2106 and P2135 diagnostic trouble codes (DTCs).

 

ACTION
Replace the throttle position sensor (TPS) following the instruction sheet included in the TPS service kit. Reprogram the powertrain control module (PCM) to the latest calibration using WDS release B36.11 and higher, or B37.2 and higher. This new calibration is not included in the B37 CD. Calibration files are also available at the website.

 

CAUTION FAILURE TO FOLLOW THE TPS REMOVAL AND INSTALLATION PROCEDURE WILL RESULT IN DAMAGE TO THE TPS SCREWS.
