Code P1502 MINI Description
The P1502 MINI diagnostic trouble code refers to an issue with the Idle Speed Control Valve Closing Solenoid Control Circuit Signal being either too high or too low. The idle speed control valve is responsible for regulating the amount of air entering the engine at idle, which in turn affects the engine's idle speed. The solenoid control circuit is a crucial component that controls the opening and closing of the idle speed control valve.
Common Causes of P1502 MINI
- Faulty idle speed control valve closing solenoid
- Damaged wiring or connectors in the solenoid control circuit
- Malfunctioning ECM
- Vacuum leak affecting the idle speed control system
Symptoms of P1502 MINI
- Erratic idle speed: The engine may idle inconsistently, with the RPMs fluctuating unexpectedly.
- Stalling: The engine may stall when coming to a stop or at idle.
- Poor acceleration: The vehicle may experience a lack of power or responsiveness when accelerating.
- Check Engine Light: The check engine light may illuminate on the dashboard.
How to Fix P1502 MINI
- Perform a thorough inspection of the idle speed control valve closing solenoid and its wiring connections.
- Test the solenoid control circuit for proper voltage and resistance.
- Replace the idle speed control valve closing solenoid if it is found to be faulty.
- Repair or replace any damaged wiring or connectors in the solenoid control circuit.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1502 MINI
The typical repair costs for addressing a P1502 MINI code can vary depending on the specific cause of the issue. In general, replacing a faulty idle speed control valve closing solenoid can cost between $150 and $300, including parts and labor. Additional costs may apply if wiring repairs or ECM replacement are needed. It is advisable to consult with a qualified mechanic or auto repair shop to get an accurate cost estimate for your specific vehicle and location. Labor rates can range from $80 to $150 per hour, so the total repair cost may also be influenced by the shop's hourly rate.
