C062B code meaning
Variable Effort Steering Module Temperature Too Low
What C062B means
C062B is set when the module or its coil driver reads a temperature below the range it is designed for. Automotive driver chips such as TI's DRV8873-Q1 are specified down to an ambient of −40 °C, so a lower reading means either an extreme cold soak or a measurement that has failed. Cold also changes the steering itself: the GM patent on temperature compensation for magnetic variable effort steering points to thicker fluid and changed electrical and magnetic behaviour, and corrects the coil current with tables tested at different temperatures, either from a fluid temperature sensor or from the current deviation. Outside its table the module cannot compensate and suspends variable effort. No maker publishes C062B. Unlike C062A, warming up usually clears it.
C062B at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.3 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C062B
- Variable effort inactive after a cold start
- Heavy or uneven steering until the system warms up
Common causes of C062B
- PossibleVehicle parked for a long time in severe frost
- PossibleOpen or failed temperature measurement inside the module or at the fluid sensor
- Less likelyMoisture or corrosion at the connector distorting the reading
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C062B 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 C062B
What does C062B mean?
C062B means "Variable Effort Steering Module Temperature Too Low". C062B is set when the module or its coil driver reads a temperature below the range it is designed for. It is a generic code, so it means the same on every make.
Is it safe to drive with C062B?
Drive gently and only to a workshop. With C062B the car can go into limp mode (reduced power) to protect itself.
Will C062B fail an emissions test?
C062B 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 C062B to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will C062B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
