C0136
Ride Height Sensor Circuit - Right Front
About C0136
The C0136 diagnostic trouble code means the chassis control module has identified a ride height sensor circuit - right front problem. This code indicates that a chassis sensor or its circuit is not providing expected readings to the ABS/stability control system. Accurate sensor data is essential for the proper operation of anti-lock brakes, traction control, and electronic stability control, and a fault in this circuit can cause these safety systems to be disabled. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.
Here are the key things to understand: Steering angle or center position incorrect. Stability control (ESC/VSC) warning light on. Speedometer reading erratically or showing zero. Loss of anti-lock braking function. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.
The most common reasons this occurs include: Contaminated or worn brake fluid level sensor. Faulty steering angle sensor. Excessive air gap between sensor and tone ring. Metallic debris on wheel speed sensor tip. Identifying the root cause is the first step toward finding the right solution.
To resolve this, follow these recommended steps: Connect an OBD-II scanner and read all stored chassis trouble codes and freeze frame data. Monitor wheel speed sensor signals using scan tool live data while driving. Inspect the affected sensor and its wiring connector for damage or corrosion. Check the sensor air gap and tone ring for damage, debris, or excessive wear. Test the sensor resistance and voltage output with a multimeter; compare to specifications. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.

Quick Answer
What causes wheel speed sensor codes?
The most common causes are a faulty sensor, damaged tone ring, excessive air gap, metallic debris on the sensor tip, corroded wiring, or a worn wheel bearing that allows the sensor to lose alignment with the tone ring.
