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.
Is the DTC active at this time?

Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.APPS RELEARN
With a scan tool select the ETC RELEARN function.
Next, erase DTCs.
Start the engine.
Does the DTC return?

Replace the APPS Assembly per Service Information. After installation iscomplete, use a scan tool and
select the ETC RELEARN function.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

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 P2116 is only enabled once test for P2167 has passed.
Set Condition:
APPS No.2 has failed to achieve the required minimum value during In Plant testing. One trip fault and the
code will be stored within 5 seconds. Engine will only idle.
