Diagnostic Test
- DTC IS ACTIVE NOTE:
Diagnose and repair any system voltage or sensor supply voltage DTCs before continuing with this test.
- Turn the ignition on.
- With the scan tool, clear DTCs in the Powertrain Control Module (PCM).
- With the scan tool, actuate the SRV Solenoid Control State.
- With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
- Go To 2.
No
- Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
- SHORT RUNNER VALVE ASSEMBLY
- Turn the ignition off.
- Disconnect the Short Runner Valve Assembly connector.
- Connect a jumper wire between the (Z908) Sensor Ground circuit and the (K237) SRV signal circuit in the Short Runner Valve Assembly harness connector.
- Turn the ignition on.
- With the scan tool, read the SRV PWM Feedback.NOTE:
The SRV PWM Feedback should be less than 3% with the jumper wire in place.
Is the SRV PWM Feedback less than 3%?
Yes
- Replace the Short Runner Valve Assembly in accordance with the Service Information. Refer to MANIFOLD, INTAKE, REMOVAL, 3.7L , MANIFOLD, INTAKE, REMOVAL, 4.7L or MANIFOLD, INTAKE, REMOVAL, 5.7L .
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 3.NOTE:
Remove the jumper wire before continuing.

- With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
- Using a 12-volt test light connected to ground, check the (F344) ASD Relay Output circuit in the Short Runner Valve Assembly harness connector.NOTE:
The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
Is the test light illuminated and bright?
Yes
- Go To 4.
No
- Repair the (F344) ASD Relay Output circuit for an open circuit or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- (Z908) SRV GROUND CIRCUIT OPEN CIRCUIT OR HIGH RESISTANCE
Courtesy of CHRYSLER GROUP, LLC
- Turn the ignition off.
- Disconnect the Powertrain Control Module (PCM) C1 harness connector.
- Measure the resistance of the (Z908) SRV ground circuit in the Short Runner Valve Assembly harness connector to ground.
Is the resistance less than 5.0 Ohms?
Yes
- Go To 5.
No
- Repair the (Z908) SRV ground circuit for an open circuit or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- (K237) SRV SIGNAL CIRCUIT SHORTED TO VOLTAGE Fig 4: Measuring Voltage Of (K237) SRV Signal Circuit In Short Runner Valve Assembly Harness Connector
Courtesy of CHRYSLER GROUP, LLC
- Turn the ignition on.
- Measure the voltage of the (K237) SRV signal circuit in the Short Runner Valve Assembly harness connector.
Is there any voltage present?
Yes
- Repair the (K237) SRV signal circuit for a short to voltage.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 6.

- Turn the ignition off.CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals, resulting in poor terminal to pin connection. Install the PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position) to perform diagnosis.
- Measure the resistance of the (K237) SRV signal between the Short Runner Valve Assembly harness connector and the appropriate terminal of PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position).
Is the resistance less than 5.0 Ohms?
Yes
- Go To 7.
No
- Repair the (K237) SRV signal for an open circuit or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- Turn the ignition off.
- POWERTRAIN CONTROL MODULE (PCM)
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Short Runner Valve Assembly and the Powertrain Control Module (PCM).
- 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.
- Perform any Technical Service Bulletins that may apply.
Were any problems found?
Yes
- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
