Code P1124 2003 Nissan Altima Sedan Description
The P1124 diagnostic trouble code (DTC) for a 2003 Nissan Altima Sedan indicates a Throttle Control Motor Relay Circuit Short. This code is related to the throttle control system in the vehicle, specifically the motor relay circuit. The throttle control motor relay is responsible for controlling the operation of the throttle control motor, which adjusts the throttle valve opening angle based on input from the engine control module (ECM). A short in the circuit can disrupt the communication between the ECM and the throttle control motor, leading to performance issues.
Common Causes of P1124 2003 Nissan Altima Sedan
- Damaged wiring or connectors in the throttle control motor relay circuit
- Faulty throttle control motor relay
- Malfunctioning throttle control motor
- Corrosion in the electrical connections
- Water intrusion in the throttle control system
Symptoms of P1124 2003 Nissan Altima Sedan
- Erratic throttle response
- Lack of power
- Stalling
- Difficulty starting the vehicle
How to Fix P1124 2003 Nissan Altima Sedan
- Begin by conducting a visual inspection of the throttle control motor relay circuit, checking for any damaged wiring or connectors.
- Test the throttle control motor relay using a multimeter to determine if it is functioning correctly.
- Inspect the throttle control motor for any signs of damage or malfunction.
- Clear the DTC from the ECM using a diagnostic scan tool after completing the repairs.
- Test drive the vehicle to ensure that the issue has been resolved and that the throttle control system is operating properly.
Cost to Fix P1124 2003 Nissan Altima Sedan
The typical repair costs for addressing a Throttle Control Motor Relay Circuit Short on a 2003 Nissan Altima Sedan can range from $150 to $400, including parts and labor.
