An implausible signal means that the data being received is incorrect, inconsistent, or out of range, which can lead to various issues with the vehicle's performance.
Common Causes of U1418
- Faulty left wheel distance sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or debris affecting sensor operation
- ECM malfunction
- Wheel bearing issues affecting sensor accuracy
Symptoms of U1418
- ABS warning light illuminated on the dashboard
- Traction control system error message displayed
- Inaccurate speedometer readings
- Vehicle pulls to one side during braking
- Increased stopping distance
How to Fix U1418
- Use a diagnostic scanner to retrieve the DTC and determine the specific cause of the issue.
- Inspect the left wheel distance sensor, wiring, and connectors for any damage or corrosion.
- Replace the faulty left wheel distance sensor if necessary.
- Clear the DTC from the ECM memory using the diagnostic scanner.
- Test drive the vehicle to ensure the issue has been resolved and that the ABS and traction control systems are functioning correctly.
Cost to Fix U1418
The typical repair costs for addressing an implausible left wheel distance signal can vary depending on the specific cause of the issue. In general, replacing a faulty wheel distance sensor and addressing related wiring or connector issues can range from $150 to $300 for parts and labor.
