The P1013 code is a manufacturer-specific powertrain code indicating a fault in a variable valve timing or lift system. Because it is manufacturer-specific, its exact definition depends entirely on the vehicle make and model.
This code identifies a detected circuit or sensor condition, not necessarily a failed component. Proper diagnosis requires verifying the exact factory definition and testing the relevant system.
Quick Navigation
Key Takeaways
- The P1013 code indicates a manufacturer-specific fault in a variable valve timing or lift system circuit.
- Possible causes include a failed position sensor, damaged wiring harness, poor electrical connections, or low engine oil pressure.
- Symptoms often include an illuminated Check Engine Light, rough idling, or reduced engine performance.
- Diagnosis requires verifying the exact factory definition and testing the specific sensor circuit with a multimeter or scan tool.
- Repairs vary by application and may involve sensor replacement, wiring repair, or oil system service.
P1013 Code Description and Implications
P1013 is a manufacturer-specific code. Its exact definition depends on the vehicle application.
Some General Motors (GM) applications: The code relates to the Intake Camshaft Position Actuator Park Position on Bank 2, indicating an issue with the variable valve timing (VVT) solenoid or circuit.
Certain BMW applications: P1013 typically indicates a plausibility or circuit fault with the Valvetronic eccentric shaft position sensor.
Specific Nissan and Infiniti applications: The code may point to a malfunction in the Variable Valve Event and Lift (VVEL) control motor position sensor circuit.
Common Causes of the P1013 Code
Several conditions can trigger this manufacturer-specific malfunction code. Identifying the exact cause requires electrical and mechanical testing.
- Failed or internally shorted/open eccentric shaft sensor, VVEL position sensor, or VVT actuator solenoid.
- Damaged, chafed, or broken wiring in the relevant sensor or actuator harness.
- Corroded, loose, or oil-contaminated electrical connectors at the sensor or solenoid.
- Low engine oil level, dirty oil, or low oil pressure preventing proper VVT actuator operation on applicable engines.
- Faulty powertrain control module or ECM (rare, usually only after circuit verification).
Symptoms Associated With P1013
Because this code involves critical engine timing or valve lift systems, symptoms typically affect engine performance and drivability.
- Illuminated Check Engine Light.
- Rough engine idling, misfires, or stalling.
- Reduced engine power, hesitation, or poor acceleration.
- Unusual mechanical noises from the valve train if the actuator is stuck or lacking oil pressure.
- Decreased fuel efficiency.
Diagnosing the P1013 Trouble Code
Diagnosis must begin by confirming the exact factory definition and locating the specific component for your vehicle.
- Verify the exact manufacturer definition and locate the specific sensor or actuator for your vehicle.
- Check the engine oil level and condition; low or degraded oil can cause VVT actuator issues on applicable engines.
- Visually inspect the external wiring harness and connectors for the affected sensor, looking for damage, corrosion, or oil intrusion.
- Use a digital multimeter to measure the resistance, reference voltage, and signal voltage of the suspect circuit and compare it to manufacturer specifications.
- Use a scan tool to monitor live data and verify sensor readings or command the VVT solenoid if supported.
Repairing the P1013 Issue
Repairs depend entirely on the confirmed root cause of the circuit or system malfunction.
- If the position sensor fails electrical or functional testing, replace the eccentric shaft sensor, VVEL sensor, or relevant position sensor.
- If wiring damage is found, repair or replace the affected harness sections and seal the connections.
- Clean or replace corroded connectors to restore proper electrical contact.
- If low oil pressure or dirty oil is confirmed, perform an oil and filter service using the correct manufacturer specification.
- If testing confirms the PCM or ECM driver is faulty and all external circuits are intact, follow the manufacturer procedure for module replacement.
Cost Considerations for P1013 Repairs
Cost depends on diagnostic time, component accessibility, required parts, programming requirements, and labor.
Sensor replacement costs vary depending on whether the component is easily accessible on the valve cover or requires significant disassembly.
Prevention Strategies for Future Occurrences
While electrical failures are not always preventable, some practices can reduce the risk of valve timing system issues.
- Maintaining proper engine oil levels and replacing oil at manufacturer-recommended intervals helps prevent VVT actuator wear and oil pressure issues.
- Inspecting exposed engine wiring and connectors can help identify developing damage from road debris or engine heat.
- Keeping connector seals intact may reduce moisture and oil intrusion in harsh environments.
Troubleshooting Tips and Best Practices
Always consult the exact manufacturer service information for your vehicle’s wiring diagram and pinout values.
- Do not assume the sensor is faulty simply because the code points to its circuit; wiring, connector, and oil pressure issues are frequently the actual cause.
- Check for related camshaft or crankshaft position codes that may indicate a broader timing or electrical issue.
- Verify technical service bulletins for your specific make and model, as some manufacturers issue updated sensors or software calibrations for recurring circuit faults.

Frequently Asked Questions
Is the P1013 code generic or manufacturer-specific?
No. P1013 is a manufacturer-specific code. Its exact definition, such as a Valvetronic sensor fault or VVT actuator issue, depends entirely on the vehicle make and model.
Can I drive my car with a P1013 code?
You can drive the vehicle, but it is not recommended. A variable valve timing or lift system fault can cause rough idling, stalling, reduced power, or severe engine damage if oil pressure is low.
Will low engine oil cause a P1013 code?
Yes, on applications where P1013 relates to a variable valve timing (VVT) actuator. These systems rely on engine oil pressure to function, and low or dirty oil can trigger the code.
Can a bad camshaft position sensor cause a P1013 code?
It depends on the application. On some vehicles, P1013 specifically points to the Valvetronic eccentric shaft sensor or VVEL position sensor, which are distinct from the standard camshaft position sensor.
Is it safe to reset the P1013 code without fixing it?
Clearing the code without repairing the underlying circuit, sensor, or oil pressure issue is not a fix. The control module will continue to monitor the system, and the code will return.
What Should You Do About the P1013 Code?
Confirm the exact factory definition for your specific vehicle application. Follow the applicable manufacturer diagnostic procedure to test the relevant variable valve timing or lift system circuit, wiring, and oil condition.
Repair or replace the confirmed failed component, then retest the system to ensure proper engine operation.
