Steering Angle Sensor Communication Circuit Fault
This code indicates a problem with the communication between the steering angle sensor and the control module.
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 steering angle sensor tracks how far you've turned the steering wheel and sends this info to the computer. If there's a problem, the computer can't get the right info, which can affect things like traction control or stability systems.
What the computer is actually seeing
The vehicle's control module expects a continuous signal from the steering angle sensor that represents the angle of the steering wheel. If this signal is lost or incorrect, it triggers the C1510 code.
What a healthy reading looks like
The expected voltage signal from the steering angle sensor should range between 0.5V to 4.5V, depending on the angle. If the signal goes outside this range or drops to zero, it indicates a fault.
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.
- 1Check the wiring and connectors for the steering angle sensor for any visible damage or corrosion. If found, repair or replace as necessary.
- 2Inspect the steering angle sensor itself. Use a multimeter to measure the resistance and voltage outputs while turning the steering wheel. Replace if out of expected values.
- 3Verify the battery voltage. It should be between 12.0V and 14.5V with the engine running. Charge or replace the battery if voltage is low.
- 4Use a scan tool to look for other related codes. If any additional codes are present, diagnose them first as they might affect the steering angle sensor operation.
Common causes
- Wiring harness damaged or corroded
- Faulty steering angle sensor
- Bad connectors
- Software glitch in the control module
- Low battery voltage
