•
When Monitored:
With the ignition on.
•
Set Condition:
The ECM detects a short to voltage on the Sensor Supply #3 circuit for 0.10 seconds.
Possible Causes
INTERMITTENT DTC
(F855) ACCELERATOR PEDAL POSITION SENSOR NO.1 5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE
(K844) CAMSHAFT POSITION SENSOR 5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE
ENGINE CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Theory of Operation
The ECM contains 3 internal 5–Volt Sensor Supply sources. Each 5–Volt Supply source is split into parallel circuits
to provide 5 volts to multiple sensors. Sensor Supply 1 provides 5 volts to the Camshaft Position Sensor and the
Accelerator Pedal Position Sensor #1.
Diagnostic Test
1.
CHECK FOR ACTIVE DTC
Turn the ignition on.
With the scan tool, erase ECM DTCs.
Turn the ignition off for 10 seconds.
Turn the ignition on.
With the scan tool, View DTCs.
Is the status Active for this DTC?
Yes
>> Go To 2
No
>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
2.
(F855) ACCELERATOR PEDAL POSITION SENSOR NO.1 5-VOLT SUPPLY CIRCUIT SHORTED TO
VOLTAGE
Turn the ignition off.
Disconnect the Accelerator Pedal Position Sensor harness connector.
Disconnect the ECM harness connectors.
Remove the ASD Relay from the IPM.
Connect a jumper wire between cavity 30 and cavity 87 of the ASD
Relay connector.
Turn the ignition on.
Measure the voltage on the (F855) Accelerator Pedal Position Sensor
No. 1 5 Volt Supply circuit.
Is the voltage below 1.0 volt?
Yes
>> Go To 3
No
>> Repair the (F855) Accelerator Pedal Position Sensor No. 1
5 Volt Supply circuit for a short to voltage.
Perform the ECM VERIFICATION TEST. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)

3.
(K844) CAMSHAFT POSITION SENSOR 5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE
Turn the ignition off.
Disconnect the Camshaft Position Sensor harness connector.
NOTE: The jumper wire should still be in place.
Turn the ignition on.
Measure the voltage on the (K844) Camshaft Position Sensor 5 Volt
Supply circuit.
Is the voltage below 1.0 volt?
Yes
>> Go To 4
No
>> Repair the (K844) Camshaft Position Sensor 5 Volt Supply
circuit for a short to voltage.
Perform the ECM VERIFICATION TEST. (Refer to 9 -
ENGINE - DIAGNOSIS AND TESTING)
4.
ENGINE CONTROL MODULE (ECM)
Turn the ignition off.
Inspect the (K844) Camshaft Position Sensor 5 Volt Supply circuit between the CMP harness connector and the
ECM harness connector.
Inspect the (F855) Accelerator Pedal Position Sensor No. 1 5 Volt Supply circuit between the APP Sensor harness
connector and the ECM harness connector
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
Look for the data to change or for the DTC to reset during the wiggle test.
Refer to any Technical Service Bulletins that may apply.
Were any problems found?
Yes
>> Repair as necessary.
Perform the ECM VERIFICATION TEST. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
No
>> Replace and program the Engine Control Module in accordance with the Service Information.
Perform the ECM VERIFICATION TEST. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)

P0700-TRANSMISSION CONTROL SYSTEM (MIL REQUEST)
For a complete wiring diagram Refer to Section 8W
•
When Monitored:
With the ignition on.
•
Set Condition:
The ECM receives a CAN Bus message indicating the presence of a DTC in the TCM.
Possible Causes
VERIFY CURRENT DTC
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.
VERIFY CURRENT DTC
NOTE: Diagnose and repair all ECM DTCs prior to diagnosing any DTCs set in the TCM.
NOTE: This code was set in the ECM by the Transmission Control Module to indicate a transmission fault.
Diagnosis of transmission faults should be done using the Transmission Diagnostic Information.
NOTE: When repairs have been completed, DTCs in the ECM and TCM must be cleared.
Turn the ignition on.
With the scan tool, erase ECM DTCs only.
With the scan tool, read ECM DTCs.
Does this DTC reset?
Yes
>> Refer to Transmission Diagnostic Information for the related symptom(s).
No
>> Test Complete.
