C0445 code meaning
Steering Wheel Position Sensor Calibration
What C0445 means
No accessible J2012 list contains C0445, and no manufacturer bulletin or service page using it could be found, so its exact meaning cannot be proven publicly. The title points to a steering wheel position sensor whose zero point was never learned or has been lost. Saab explains for the 9-5 that the sensor only knows straight ahead after a calibration, which is due after front-end work or a sensor swap. Mitsubishi resets both the sensor neutral point and the value stored in the stability unit after an alignment, and HELLA warns that a wrong zero upsets stability control. On the 2011 Saab 9-5, GM files this condition under C0710 symptom 42 instead. Expect the stability warning lamp and ESC out of action until the sensor is calibrated.

Symptoms of C0445
- ESC or traction control warning lamp on
- Stability control unavailable
- Steering wheel reading not zero when driving straight (scan tool)
Common causes of C0445
- Most likelyZero-point calibration skipped after alignment, steering work or sensor replacement
- PossibleStored calibration lost after battery disconnection or low voltage
- Less likelyStability control module replaced or reprogrammed without relearning the angle
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0445 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 C0445
What does C0445 mean?
C0445 means "Steering Wheel Position Sensor Calibration". No accessible J2012 list contains C0445, and no manufacturer bulletin or service page using it could be found, so its exact meaning cannot be proven publicly. It is a generic code, so it means the same on every make.
Is it safe to drive with C0445?
Drive gently and only to a workshop. With C0445 the car can go into limp mode (reduced power) to protect itself.
Will C0445 fail an emissions test?
C0445 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 C0445 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1 hours of work. This is a job for a workshop.
Will C0445 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
