P0D9E Battery Charger A Coupler Lock Position Sensor Circuit
The lock position sensor tells the vehicle whether the pin that holds the charging plug in the inlet is extended or retracted. Without that feedback the car cannot confirm a latched plug and refuses fast charging. A GM patent, US8936482B2, measures how far the actuator has moved the pin, with a Hall element, a potentiometer or an end-stop switch as options. P0D9E is the general circuit fault of this feedback. Ford lists P0D9E:00 in TSBs 22-2355 and 23-2014 for the F-150 Lightning, Mach-E and e-Transit built 2021 to 2023, stored by the SOBDM together with P0D93, P0D94, P0D98 and P0DA0. The cause there is mechanical: pulling the DC plug without holding the release button down breaks or loses the actuator pin, and Ford swaps only the lock actuator. Range, low, high and intermittent faults are P0D9F to P0DA2.
Likely causes
Symptoms
- DC fast charging inoperative
- Charger Service Required message in the cluster (Ford)
- Locking pin visibly damaged or absent at the inlet
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
