What it means
The control module monitors its operating temperature. It sets this code when the variable effort steering module reports a temperature below the expected range.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
The variable-effort steering module monitors its operating temperature through a temperature-sensing circuit. This code sets when the module reports a temperature below the expected range, which can indicate a sensor or circuit fault rather than genuinely cold conditions.
Common causes
Most likely first.
- Temperature sensor fault
- Damaged wiring or poor connection to the sensor
- Control module fault
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Record freeze-frame data and scan for related steering or electrical codes to check whether the low-temperature report appeared with other sensor faults.
- Compare the module's reported temperature with ambient conditions and other available temperature readings for plausibility.
- Inspect the temperature sensor connection and nearby harness for corrosion, loose terminals, damaged insulation, or water entry.
- Check the sensor circuit's power, ground, and signal according to the wiring diagram and manufacturer's specification.
- Watch live temperature data while gently moving the harness to identify intermittent connections or dropouts.
- If wiring and connections pass, test the temperature sensor and module input using the manufacturer's procedure.
Common fixes
- Clean and secure the temperature-sensor connector.
- Repair damaged wiring or poor circuit connections.
- Replace the temperature sensor if it fails the specified test.
- Repair or replace the control module if its input is confirmed faulty.
Can I keep driving?
The code may leave steering-related stability functions limited even if the vehicle does not enter limp mode. Drive cautiously, allow for reduced assistance, and stop if steering or braking behavior becomes abnormal.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
