C0455Steering Wheel Position Sensor Circuit
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0455 is absent from the accessible J2012 lists but well documented at GM, where the electronic brake control module (EBCM) stores it for the steering wheel position sensor circuit. Bulletin PI0639C, covering 2007–2016 full-size pickups, SUVs, vans and the Colorado/Canyon, blames rising resistance between sensor and EBCM caused by fretting corrosion and a connector with too much play; it says not to replace the sensor but to fit shim stock and apply dielectric grease. PIT4225F adds a steering wheel fitted off its master spline, and PIT5207 an EBCM programmed for the wrong sensor design on 2010 hybrids. The driver sees Service StabiliTrak, often together with C0710.
