Code P124D Description
The P124D diagnostic trouble code (DTC) indicates that the positive voltage control circuit for injector 6 is shorted to the control circuit. In modern fuel-injected engines, each cylinder has its own fuel injector responsible for delivering the precise amount of fuel needed for combustion. The injector is controlled by the engine control module (ECM) which sends signals to open and close the injector at the right time. When the positive voltage control circuit for injector 6 is shorted to the control circuit, it means that there is an unintended connection between these two circuits, causing a malfunction in the injector's operation.
Common Causes of P124D
- Damaged wiring harnesses
- Faulty connectors
- Short circuit in the injector
- Issues with the engine control module (ECM)
- Electrical interference or corrosion in the wiring system
Symptoms of P124D
- Misfire in cylinder 6
- Rough idle
- Hesitation or lack of power during acceleration
- Decreased fuel efficiency
- Engine stalling
How to Fix P124D
- Begin by conducting a thorough visual inspection of the wiring harnesses and connectors related to injector 6 to check for any visible damage or corrosion.
- Use a multimeter to test the continuity and resistance of the positive voltage control circuit for injector 6 to identify any short circuits.
- Inspect the injector itself for any signs of damage or malfunction, and replace it if necessary.
- If no issues are found with the wiring or injector, perform a diagnostic scan to check for any faults in the engine control module (ECM) that may be causing the short circuit.
- Once the root cause is identified, repair or replace the faulty components as needed, clear the DTC, and test the vehicle to ensure that the issue has been resolved.
Cost to Fix P124D
The typical repair costs for addressing a P124D code can vary depending on the specific cause of the issue and the vehicle's make and model. In general, the cost of parts for this repair could range from $50 to $200, while labor costs could be between $100 and $300. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your location and vehicle type.
