P2108-ELECTRONIC THROTTLE CONTROL MODULE PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on.
Set Condition:
Internal PCM failure. Customer may experience an extended cranking condition with limited driving and a
rough idle. One trip fault and the code will set within 5 seconds. ETC light is flashing.
Possible Causes
POWERTRAIN CONTROL MODULE NEEDS TO BE REPROGRAMMED
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.REPROGRAM THE POWERTRAIN CONTROL MODULE
Check for any related TSBs.
Verify the PCM is at the latest calibration (flash level).
NOTE: Inspect the Intake Manifold components for vacuum leaks, repair as necessary
NOTE: An intermittent loss of power to the PCM without performing an ETC Relearn procedure may cause
this DTC to set.
NOTE: Diagnose any other DTCs that may have set with the P2108.
Flash the Powertrain Control Module per Service Information if any updates are available.
Start the engine.
Allow the engine to reach normal operating temperature.
Operate the accelerator pedal. (do not exceed 3500 rpm)
Test drive the vehicle for 10 miles on a flat road surface.

P2115-ACCELERATOR PEDAL POSITION SENSOR 1 MINIMUM STOP
PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on. During in plant mode the APP Sensors need to be checked to make sure that idle and full pedal
travel can be reached on both sensors. The test for P2115 is only enabled once test for P2166 has passed.
Set Condition:
APPS No.1 has failed to achieve the required minimum value during In Plant testing. One trip fault and the
code will set within 5 seconds. Engine will only idle.
Possible Causes
IN PLANT TEST FAILURE
APPS RELEARN
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.IN PLANT TEST FAILURE
Ignition on, engine not running.
NOTE: This DTC is set when the APP Sensors are learned in plant but do not reach the Minimum or Max-
imum voltage range.
With a scan tool read DTCs.
With the scan tool, erase DTCs.
Start the engine.
With the scan tool, read DTCs.
NOTE: Diagnose any APPS out of Range and 5-Volt Supply DTCs before continuing.
