C0460 code meaning
Steering Position Signal Implausible
What C0460 means
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.

- Limp modePossible

- Typical labor0.3 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of C0460
- Traction or stability control lamp on
- Reduced Steering Assist message, sometimes without actual loss of assist
- Stability control switched off
Common causes of C0460
- Most likelyBrief low voltage leaving the sensor uninitialised
- PossibleSensor trim error or control module software (GM 17-NA-284)
- PossibleAngle offset after alignment or steering work
- Less likelySteering angle sensor or column module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C0460 means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 60 | The exact fault in that area. |
What to do next
- Note C0460 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0460
What does C0460 mean?
C0460 means "Steering Position Signal Implausible". C0460 is not in the accessible J2012 lists; GM and Saab use it for the steering angle signal. It is a generic code, so it means the same on every make.
Is it safe to drive with C0460?
Drive gently and only to a workshop. With C0460 the car can go into limp mode (reduced power) to protect itself.
Will C0460 fail an emissions test?
C0460 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0460 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will C0460 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
