P1062 is a manufacturer-specific powertrain code, and its exact definition depends on the vehicle application. It may indicate a variable valve lift system malfunction, an oil supply solenoid fault, or an injector circuit issue.
Because definitions vary significantly by manufacturer, exact application verification is required. The code indicates a detected condition, and proper diagnosis depends on following the specific manufacturer’s diagnostic workflow before replacing parts.
Quick Navigation
Key Takeaways
- P1062 is a manufacturer-specific code with different definitions for BMW, Chrysler, and Alfa Romeo applications.
- On BMW and MINI applications, it typically indicates a variable valve timing system fault where full stroke position is not reached.
- On Chrysler and Dodge applications, it indicates a Cylinder 2 oil supply solenoid valve stuck fault.
- Proper diagnosis requires verifying the exact code definition for your specific vehicle before replacing any components.
P1062 Code Description and Implications
P1062 is a manufacturer-specific error code, meaning its exact definition depends entirely on the vehicle application. It does not have one universal monitored system.
BMW and MINI applications: P1062 indicates a variable valve timing or Valvetronic system fault where the full stroke position is not reached. The engine control module detects that the valve lift system cannot achieve its target position.
Chrysler and Dodge applications: P1062 indicates a Cylinder 2 oil supply solenoid valve stuck fault within the variable valve actuator system.
Alfa Romeo and Fiat applications: P1062 points to a MultiAir variable valve lift position regulation fault or timing sensor issue.
When a control module detects a parameter outside its expected range, it stores a code and may illuminate the Check Engine Light.
Common Causes of the P1062 Code
Diagnostic trouble codes stem from various electrical, mechanical, and environmental factors specific to the monitored system.
For BMW and MINI applications: Possible causes include oil contamination in the eccentric shaft sensor connector, a failing Valvetronic actuator motor, worn VANOS solenoids, or damaged wiring.
For Chrysler and Dodge applications: Possible causes include a mechanically stuck cylinder oil supply solenoid, low engine oil pressure, or incorrect oil viscosity.
For Alfa Romeo and Fiat applications: Possible causes include MultiAir module failure, low oil level, or aerated engine oil.
Symptoms Associated With P1062
Symptoms vary widely depending on the specific system affected and the severity of the detected condition.
On BMW and MINI applications: You may notice the vehicle entering a limp home mode with reduced power, rough idling, or poor fuel economy due to the valve timing restriction.
On Chrysler and Dodge applications: Symptoms may include engine misfires on cylinder 2, rough running, or reduced performance.
MIL behavior varies by application. Some vehicles may illuminate the Check Engine Light immediately, while others may require multiple drive cycles to command it.
Diagnosing the P1062 Trouble Code
Diagnosis must begin by confirming the exact make, model, year, and engine to determine the correct factory definition.
For BMW and MINI applications: Inspect the eccentric shaft sensor connector for oil intrusion. Test the Valvetronic actuator and VANOS solenoids using live data and manufacturer-specific bidirectional controls.
For Chrysler and Dodge applications: Verify engine oil level and pressure. Test the cylinder oil supply solenoid circuit for proper operation and check for mechanical binding.
For Alfa Romeo and Fiat applications: Check the MultiAir module oil feed and verify the condition of the engine oil and filter.
Repairing the P1062 Issue
Repairs must follow confirmed diagnostic testing to address the root cause of the fault.
If wiring damage or connector corrosion is found, repair the harness and ensure proper environmental sealing.
If a Valvetronic motor, eccentric shaft sensor, or oil supply solenoid fails manufacturer testing, replace it with a component meeting the exact vehicle specification.
On applications where oil contamination is confirmed, cleaning the connector and replacing the valve cover gasket may be necessary to prevent recurrence.
Cost Considerations for P1062 Repairs
Cost depends on diagnostic time, component accessibility, required parts, programming requirements, and labor.
Replacing a VANOS solenoid or cleaning a sensor connector is generally straightforward. However, replacing an integrated Valvetronic actuator or MultiAir module requires significant labor and specialized calibration equipment.
Prevention Strategies for Future Occurrences
Inspecting exposed wiring harnesses and ensuring electrical connectors remain clean and dry can help prevent intermittent circuit faults.
Maintaining proper engine oil levels, using the correct oil viscosity, and adhering to strict oil change intervals helps prevent mechanical failures in variable valve lift systems that rely on oil pressure.
Troubleshooting Tips and Best Practices
Do not assume a generic code description or a definition from one brand applies to your vehicle. Always verify the exact factory definition for your specific application.
Check for technical service bulletins related to software updates or revised components. Certain applications require specific ECM relearn procedures after any variable valve timing component replacement.

Frequently Asked Questions
Is P1062 a generic OBD-II code?
No. P1062 is a manufacturer-specific code. Its exact definition depends on the vehicle application, and it can refer to a variable valve lift fault or an oil solenoid issue.
Can I drive my car with a P1062 code?
Driving safety depends on the specific application and symptoms. If the vehicle enters a limp home mode or experiences severe misfires, driving is not recommended until the issue is diagnosed.
Will a P1062 code cause an emissions test failure?
Yes. Because P1062 relates to emissions monitors, variable valve timing, or powertrain systems, an active code will likely cause the vehicle to fail an OBD-II emissions inspection.
Can an oil change fix a P1062 code?
An oil change alone rarely fixes the code if a component has failed. However, on systems relying on oil pressure, correcting low oil levels or using the wrong viscosity may resolve the fault.
Can I clear the P1062 code by disconnecting the battery?
Disconnecting the battery may temporarily clear the code, but it does not repair the underlying fault. It also resets readiness monitors, which can cause the vehicle to fail an emissions inspection.
What Should You Do About the P1062 Code?
Confirm the exact factory definition for any stored codes based on your specific vehicle make, model, and engine configuration. Because P1062 is manufacturer-specific, following the applicable diagnostic procedure is essential.
Inspect the relevant system and components for confirmed faults. Repair or replace the confirmed failed components, then retest the system and complete the necessary drive cycles to verify the repair.
