C0455 Code: Steering Wheel Position Sensor Circuit Failure

The C0455 code means there is a fault in the steering wheel position sensor. The stability control is left disabled and, on some vehicles, so is the variable power steering.

What the C0455 code means

The ABS module (EBCM) controls the anti-lock brakes and, on most modern vehicles, traction control and stability control too. When it detects a fault, it disables those functions and turns on the ABS and stability warning lights. The normal brakes keep working.

The steering wheel position sensor (steering angle) reports which way the driver is turning. The stability control compares that with the real rotation of the vehicle. If the signal fails, the stability control shuts off and the C0455 code is stored.

After an alignment, or after replacing the steering column or the clockspring, the sensor needs to be calibrated with the scan tool.

Important: many C and B codes are not generic. The definition on this page is the most widespread one, used by General Motors and most generic scan tools, but on other makes the same number can mean something else. Always confirm the code text with a scan tool that reads the right module (ABS, body or airbag).

A typical symptom after an alignment is a crooked steering wheel with the vehicle driving straight. First correct the alignment so the wheel sits straight, and then calibrate the sensor. If it is calibrated with the wheel crooked, the stability control will act incorrectly.

C0455 code symptoms

  • Stability control warning light on.
  • Crooked steering wheel after an alignment.

Likely causes of the C0455 code

  1. Sensor not calibrated after an alignment or a repair.
  2. Damaged sensor from impacts, moisture or an internal failure.
  3. Connector or wiring that is damaged or wet, often under the carpet.
  4. Clockspring, if the sensor is built into it.

How to diagnose the C0455 code step by step

  1. With the wheels straight, check that the scan tool reads 0 degrees.
  2. Calibrate the sensor.
  3. Inspect the connector.
  4. Correct the alignment before calibrating. The steering wheel must sit straight.

How to fix the C0455 code

  • Calibrate or replace the sensor.
  • Repair the wiring.

Technical reference data

  • With the wheels straight: 0 degrees, with a tolerance of a few degrees.
  • These values are approximate. Check the manufacturer data for your vehicle.

Brand-specific notes

Ask the alignment shop whether they calibrate the steering angle sensor. On many vehicles it is a required step, and skipping it is the most common reason this code shows up right after an alignment.

C0455 on GM, Toyota and Nissan

This code is common on GM, Toyota and Nissan vehicles after an alignment.

Frequently asked questions about C0455

What does the C0455 code mean?
It means the ABS module found a fault in the steering wheel position sensor circuit, so the stability control cannot work.
Can I drive with a C0455 code?
Yes, but the C0455 code leaves the stability control off. Take extra care in curves and on slippery roads.
Does it have to be calibrated after an alignment?
Yes, on most vehicles with stability control.
What usually fails?
The calibration.
How much does it cost to fix C0455?
Between $30 and $400. A calibration is at the low end, and a new sensor is at the high end.
Will a C0455 code clear itself?
Not usually. Until the sensor is calibrated or repaired, the code stays and the stability control stays off.
