Code C1428 Toyota Description
The C1428 diagnostic trouble code (DTC) for Toyota indicates a malfunction in the actuator pump motor circuit. The actuator pump motor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. The actuator pump motor is responsible for building hydraulic pressure in the ABS system to help control wheel speed during braking and prevent wheel lock-up. When this circuit malfunctions, it can significantly impact the performance of the vehicle's ABS system, potentially compromising the vehicle's ability to safely brake and maintain traction on slippery roads.
Common Causes of C1428 Toyota
- Faulty actuator pump motor
- Damaged wiring or connectors in the actuator pump motor circuit
- Corrosion or moisture intrusion in the ABS system
- ABS control module malfunction
- Sensor issues affecting the ABS system
Symptoms of C1428 Toyota
- Illuminated ABS warning light on the dashboard
- Increased braking distance
- Loss of traction control functionality
- Unusual noises coming from the ABS system
- ABS system engaging unexpectedly or inconsistently
How to Fix C1428 Toyota
- Perform a comprehensive diagnostic scan to retrieve the specific DTC and pinpoint the cause of the malfunction.
- Inspect the actuator pump motor, wiring, connectors, and ABS system components for any visible damage or corrosion.
- Test the actuator pump motor and related components to determine if they are functioning properly.
- Replace the faulty actuator pump motor, repair damaged wiring or connectors, and address any other issues identified during the diagnostic process.
- Clear the DTC and perform a road test to ensure the ABS system is operating correctly.
Cost to Fix C1428 Toyota
