P2116-ACCELERATOR PEDAL POSITION SENSOR 2 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 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.
Possible Causes
IN PLANT TEST FAILURE
APPS RELEARN
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
