Diagnostic Test

DETERMINING IF RELATED ENGINE TPS DTCS ARE PRESENT
1. With the scan tool, check Engine DTCs, including pending DTCs and one trip failures.
  Are there any Engine TPS DTCs present?
  
  Yes
  - Refer to the Driveability category and perform the appropriate diagnostic procedure.
  - Perform 42RLE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Go to step 2
CHECK IF THE DTC IS CURRENT
1. With the scan tool, record the Event Data to help identify the conditions in which the DTC was set.
2. With the scan tool, erase Transmission DTCs.
  NOTE: Clearing DTCs does NOT erase the Event Data. To erase the Event Data you must either perform a Quick Learn procedure or battery disconnect (if available) with the scan tool, or manually disconnect the battery. Whatever method used might reset certain learned transmission values to controller defaults and may cause poor shift quality until those values are relearned.
3. Drive the vehicle and try to duplicate the conditions in which the DTC was reported by the Event Data.
4. With the scan tool, read Transmission DTCs.
  Does this DTC reset?
  
  Yes
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace and program the PCM per the Service Information. With the scan tool, perform Quick Learn.
  - Perform 42RLE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Go to step 3
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. Pay particular attention to the TPS signal and sensor ground circuits.
5. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
6. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform 42RLE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Test Complete.
