Diagnostic Test
WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK FOR ACTIVE DTCS NOTE:
If there are any 5-Volt Supply DTCs present, perform the Diagnostics for those DTCs before continuing with this one.
- Turn the ignition on.
- Using the scan tool, erase PCM DTCs.
- Perform several ignition cycles, turning the ignition off for at least 10 seconds between each ignition cycle.
- Monitor the scan tool for PCM DTCs.
Did this DTC return?
Yes
- Go To 2
No
- Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
- CHECK THE (K22) THROTTLE POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND NOTE:
There is an in-line harness connector that will allow easier access to these circuits for testing.
- Turn the ignition off.
- Disconnect the TV Actuator harness connector.
- Disconnect the PCM C2 harness connector.
- Measure the resistance between ground and the (K22) Throttle Position Signal circuit at the TV Actuator harness connector.
Is the resistance above 10k Ohms?
Yes
- Go To 3
No
- Repair the (K22) Throttle Position Signal circuit for a short to ground.
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
- CHECK FOR THE (K22) THROTTLE POSITION SIGNAL CIRCUIT SHORTED TO THE (K922) SENSOR GROUND CIRCUIT
- Measure the resistance between the (K22) Throttle Position Signal circuit and the (K922) Sensor Ground circuit at the TV Actuator harness connector.
Is the resistance above 10k Ohms?
Yes
- Go To 4
No
- Repair the short between the (K22) Throttle Position Signal circuit and the (K922) Sensor Ground circuit
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
- Measure the resistance between the (K22) Throttle Position Signal circuit and the (K922) Sensor Ground circuit at the TV Actuator harness connector.
- CHECK THE (K22) THROTTLE POSITION SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
- Measure the resistance of the (K22) Throttle Position Signal circuit between the TV Actuator harness connector and the PCM C2 harness connector
Is the resistance above 5.0 Ohms?
Yes
- Repair the (K22) Throttle Position Signal circuit for an open/high resistance.
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
No
- Go To 5
- Measure the resistance of the (K22) Throttle Position Signal circuit between the TV Actuator harness connector and the PCM C2 harness connector
- CHECK THE (K922) SENSOR GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE
- Measure the resistance of the (K922) Sensor Ground circuit between the TV Actuator harness connector and the PCM C2 harness connector
Is the resistance above 5.0 Ohms?
Yes
- Repair the (K922) Sensor Ground circuit for an open/high resistance.
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
No
- Go To 6
- Measure the resistance of the (K922) Sensor Ground circuit between the TV Actuator harness connector and the PCM C2 harness connector
- THROTTLE VALVE ACTUATOR
- Reconnect the TV Actuator harness connector.
- Reconnect the PCM C2 harness connector.
- Turn the ignition on.
- With the scan tool, erase DTCs.
- Turn the ignition off.
- Disconnect the TV Actuator harness connector.
- Connect a jumper between the (K22) Throttle Position Signal circuit and the (K313) 5-Volt Supply circuit at the TV Actuator harness connector.
- Turn the ignition on.
- With the scan tool, select View DTCs.
Does the scan tool display DTC P02E9?
Yes
- Replace the Throttle Valve Actuator in accordance with the service information.
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
No
- Go To 7
- POWERTRAIN CONTROL MODULE
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the TV Actuator 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.
- Perform any Technical Service Bulletins that may apply.
Were any problems found?
Yes
- Repair as necessary.
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
No
- Replace the Powertrain Control Module in accordance with the service information. Refer to REMOVAL .
- Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
