(K126) ETC NEGATIVE CIRCUIT OPEN
Measure the resistance of the (K126) ETC Negative circuit between the
Throttle Body harness connector and the appropriate terminal of special
tool #8815.
Is the resistance below 5.0 ohms?
Yes
>> Go To 6
No
>> Repair the open in the (K126) ETC Negative circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
6.
(K124) ETC POSITIVE CIRCUIT SHORTED TO GROUND
Measure the resistance between a known good ground and the (K124)
ETC Positive circuit at the appropriate terminal of the special tool
#8815.
Is the resistance below 100 ohms?
Yes
>> Repair the short to ground in the (K124) ETC Positive cir-
cuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)

P2115-ACCELERATOR PEDAL POSITION SENSOR 1 MINIMUM STOP
PERFORMANCE
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
Igniting 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?
Yes
>> Go To 2
No
>> 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?
Yes
>> Replace the APPS Assembly per Service Information. After installation is complete, use a scan tool and
select the ETC RELEARN function.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Test Complete.
