Code C0035:18 Description
The C0035:18 code indicates that there is a low signal amplitude in the left front wheel speed sensor circuit. This sensor is responsible for monitoring the speed of the wheel and sending that information to the vehicle's electronic control module (ECM). The ECM uses this data to make decisions regarding the vehicle's anti-lock braking system (ABS) and traction control system.
Common Causes of C0035:18
- Faulty wheel speed sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or dirt buildup on the sensor
- Issues with the ECM or ABS module
- Electrical interference or short circuits in the sensor circuit
Symptoms of C0035:18
- ABS warning light illuminated on the dashboard
- Traction control system malfunction
- Erratic braking behavior, such as pulsating brakes
- Increased stopping distance
- Loss of traction on slippery surfaces
How to Fix C0035:18
- Perform a visual inspection of the wheel speed sensor and its wiring for any visible damage or corrosion.
- Test the wheel speed sensor using a multimeter to check for proper voltage and continuity.
- Clean the sensor and its mounting area to ensure a proper connection.
- Replace the wheel speed sensor if it is faulty or damaged.
- Clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C0035:18
The typical repair costs for addressing a C0035:18 code can range from $100 to $300, including the cost of a new wheel speed sensor and labor. However, specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's recommended to check with local repair shops for a more accurate estimate. Labor rates generally range between $80 and $150 per hour, but rates may be higher in metropolitan areas or at dealerships.
