Rear Camera Sensor Circuit Fault

This code indicates a problem with the rear camera sensor circuit.

Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.

What it means (plain English)

The vehicle's computer is not getting the right signals from the rear camera sensor, which means the backup camera may not work properly.

What the computer is actually seeing

The module expects to see a voltage signal between 0.5V to 4.5V from the rear camera sensor depending on its position and operation. If the signal is too low or too high, or if it is absent, the code triggers.

What a healthy reading looks like

Voltage from sensor should be within 0.5V to 4.5V, with a normal image signal appearing within milliseconds of activation.

Guided diagnostic — the DiagCoach way

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

  1. 11. Inspect the wiring and connectors at the rear camera for damage or corrosion. If found, repair or replace as needed. Decision: Is wiring intact? (Yes: proceed to step 2; No: repair wiring)
  2. 22. Check the voltage at the rear camera connector with the camera activated. Expected voltage between 0.5V to 4.5V. Decision: Is the voltage within spec? (Yes: replace the rear camera; No: check for short circuit or open circuit in wiring)
  3. 33. If replacing the camera does not clear the code, test the circuit continuity from the module back to the camera. Decision: Is there continuity? (Yes: further diagnosis needed on module; No: repair the circuit)

Common causes

  • Damaged wiring or connectors in the rear camera circuit
  • Faulty rear camera sensor
  • Water intrusion or corrosion in the sensor area

Typical repair cost
