P0010
P0010-BANK 1 CAMSHAFT 1 POSITION ACTUATOR CIRCUIT OPEN
- When Monitored:
With the engine running and battery voltage greater than 10.4 volts.
- Set Condition:
The PCM detects that the actual state of the VVT Intake Solenoid does not match the intended state.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure
1. DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, record the related Freeze Fame Data and clear the DTCs in the Powertrain Control Module (PCM).
3. Start the engine and allow it to reach normal operating temperature. Hold engine speed greater than 1,000 rpm for at least one minute. The DTC will not be set unless cam phasing becomes active, which may not occur if speed never leaves idle.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result possible serious or fatal injury.
4. With the scan tool, select View DTCs.
Is the DTC Active or Pending at this time?
Yes
- Go to 2
No
- Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. Checking for an Intermittent DTC
2. (F344) FUSED ASD/MAIN RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Disconnect the VVT Intake Solenoid connector.
3. Turn the ignition on.
4. Using a 12 volt test light connected to ground, check the (F344) Fused ASD/Main Relay Output circuit in the VVT Intake Solenoid 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 3
No
- Repair the (F344) Fused ASD/Main Relay Output circuit for an open circuit or high resistance.
- Perform the PCM Verification Test. PCM Verification Test
3. (K76) VVT INTAKE CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM).
NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals. Improper measurement technique could result in poor pin to terminal contact.
3. Measure the resistance of the (K76) VVT Intake Control circuit between the VVT Intake Solenoid harness connector and the Powertrain Control Module (PCM) harness connector.
Is the resistance below 5.0 ohms?
Yes
- Go to 4
No
- Repair the (K76) VVT Intake Control circuit for an open circuit or high resistance.
- Perform the PCM Verification Test. PCM Verification Test
4. VVT INTAKE SOLENOID ACTUATION
1. Connect the Powertrain Control Module (PCM) harness connector.
2. Turn the ignition on.
3. Using a 12 volt test light connected to 12 volts, check the (K76) VVT Intake Control circuit in the VVT Intake Solenoid harness connector.
NOTE: The test light should be off unless you have a short to ground, except for a brief period immediately after turning ignition on.
4. With the scan tool, actuate the VVT Intake Solenoid Control to the ON (100%) position.
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 5
No
- Go to 6
5. VVT INTAKE SOLENOID
1. Turn the ignition off.
2. Inspect the wiring and connectors between the VVT Intake Solenoid and the Powertrain Control Module (PCM).
3. Verify that there is good pin to terminal contact in the Camshaft Position Solenoid (VVT Solenoid) and Powertrain Control Module connectors.
4. Look for any chafed, pierced, pinched, or partially broken wires.
5. Look for broken, bent, pushed out or corroded terminals.
6. Look for signs of water intrusion past the connector seal.
Were any problems found?
Yes
- Repair as necessary.
- Perform the PCM Verification Test. PCM Verification Test
No
- Replace the VVT Intake Solenoid.
- Perform the PCM Verification Test. PCM Verification Test
6. POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the VVT Intake Solenoid and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Search for any Technical Service Bulletins that may apply.
Were any problems found?
Yes
- Repair as necessary.
- Perform the PCM Verification Test. PCM Verification Test
No
- Replace and program the Powertrain Control Module (PCM).
