Code P1124 Description
The P1124 diagnostic trouble code indicates a problem with the throttle control motor relay circuit in the vehicle's electronic throttle control system. The throttle control motor relay is responsible for controlling the movement of the throttle plate in response to driver input. A short circuit in this circuit can lead to issues with throttle response, potentially causing poor acceleration, stalling, or even a complete loss of throttle control.
Common Causes of P1124
- Faulty throttle control motor relay
- Wiring or connector issues in the relay circuit
- Corrosion or damage to electrical connections
- Short circuit in the circuitry
- Electronic control module (ECM) failure
Symptoms of P1124
- Engine stalling or hesitation
- Reduced acceleration or lack of response to throttle input
- Illuminated Check Engine Light
- Rough idling or uneven engine performance
- Vehicle going into "limp mode" to prevent further damage
How to Fix P1124
- Begin by diagnosing the specific cause of the issue using a diagnostic scanner to pinpoint the faulty component.
- Inspect the throttle control motor relay and associated wiring for any visible damage or corrosion.
- Test the relay and circuitry for continuity and proper voltage using a multimeter.
- Replace the faulty throttle control motor relay or repair any damaged wiring or connectors.
- Clear the diagnostic trouble codes and perform a test drive to ensure the issue has been resolved.
Cost to Fix P1124
The cost of repairing a throttle control motor relay circuit short can vary depending on the extent of the damage and the specific components that need to be replaced. In general, the parts for this repair can range from $50 to $200, while the labor costs can add another $100 to $200. Overall, the total repair cost is typically between $150 and $400. However, as mentioned earlier, actual costs can fluctuate based on various factors, so it's recommended to obtain quotes from local auto repair shops for a more accurate estimate.
