how to diagnose C0035 code on Ford F-150 12th Generation (2009-2014)

Solution

1. Preparation

• Gather necessary tools and materials.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Clean the Wheel Speed Sensor

• Remove the left front wheel to access the wheel speed sensor.
• Locate the wheel speed sensor and disconnect its electrical connector.
• Clean any dirt or debris from the sensor and its mounting area.
• Reconnect the sensor and ensure the connection is secure.

3. Replace the Wheel Speed Sensor (if necessary)

• If the sensor is damaged or fails resistance testing:
  1. Remove the mounting bolt(s) securing the wheel speed sensor.
  2. Carefully pull the sensor from its housing.
  3. Install the new wheel speed sensor, ensuring it is oriented correctly.
  4. Tighten the mounting bolt(s) to the manufacturer's specified torque (usually around 12-15 lb-ft).

4. Inspect and Replace Wiring (if needed)

• If wiring is damaged:
  1. Cut away any damaged sections of wire.
  2. Strip the ends of the wires and solder new wire sections as necessary.
  3. Use heat shrink tubing to insulate the connections.
  4. Reconnect the wiring harness securely.

5. Reassemble and Reconnect

• Reinstall the left front wheel.
• Reconnect the negative battery terminal.
• Perform a visual inspection of all components to ensure everything is correctly reassembled.
