C0460Steering Position Signal Implausible

  • Generic OBD-II code · Chassis
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
C0460 is not in the accessible J2012 lists; GM and Saab use it for the steering angle signal. On the 2016 Malibu the EBCM sets it after a brief low-voltage event, and turning lock to lock with ignition on resets the sensor (16-NA-151). On 2017–2018 XT5 and Acadia, C0460 symptom 5A in the power steering module came from a sensor trim error and is fixed by reprogramming (17-NA-284); PIE0481A pairs it with C0545 on 2009–2012 Malibu, G6 and Aura. The Saab 9-3 sets it if the angle rate passes 3000°/s, the computed offset passes 18°, the angle exceeds ±720° or freezes. Lotus uses C0460 for something else: the pressure sensor in Bosch ESP8 units, often tripped by a misadjusted brake light switch.
