DTC B1D23 Overheat Sensor: Action
WARNING: This page is about a different car, the 2017 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
DIAGNOSE any other PSCM DTCs before diagnosing DTC B1D23:4B. If no other DTCs are present, INSPECT the EPAS gear heat shield. INSTALL new as necessary. ADVISE the customer that high ambient temperatures or heavy loads on the EPAS system cause this DTC to set, resulting in higher than usual steering effort. 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.
