Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
This DTC alone does not indicate a fault in the PSCM. It indicates an overtemperature condition due to ambient conditions and/or a heavy load on the EPAS system. A heavy load is defined as multiple parking lot maneuvers over a short duration of time with low tire pressure or towing for long distances followed by multiple parking maneuvers.
The thermistor used by the PSCM is calibrated for 80°C (176°F) and as ambient temperature decreases, so does the accuracy of the sensor. At room temperature and lower, the sensor will be +/- 20°C (68°F).
