What Does U023E Mean?
The right front distance range sensor for adaptive cruise control has stopped communicating. This sensor works with the left sensor to provide accurate distance measurement and object detection for safety features.
Common Causes
35%
Defective right front distance sensor module
30%
Wiring harness or connector damage to right sensor
20%
Sensor physical damage or calibration loss from collision
10%
Loss of power or ground to right sensor
5%
CAN network fault affecting sensor communication
Diagnostic Steps
1
Step 1: Visually inspect right front bumper and sensor for damage or misalignment
2
Step 2: Test voltage supply and ground at sensor connector using multimeter
3
Step 3: Check sensor connector terminals and wiring for corrosion or breaks
4
Step 4: Measure CAN bus voltages at sensor to verify network communication
5
Step 5: Replace sensor if all wiring checks pass; perform sensor aiming and calibration procedure
Estimated Repair Cost
$300 - $1,800
Parts + labor, varies by vehicle and location
The right front distance range sensor for adaptive cruise control has stopped communicating. This sensor works with the left sensor to provide accurate distance measurement and object detection for safety features.
The most common cause of U023E (Lost Communication With Cruise Control Front Distance Range Sensor Right) is: Defective right front distance sensor module
Typical repair costs for U023E range from $300 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Adaptive cruise control and pre-collision systems will be disabled or degraded. Driver must monitor traffic and control speed manually without automated assistance.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U023E to identify the root cause.
