P2889 Park Lock/Pawl Actuator Circuit Low

P2889 reports that the park lock actuator circuit sits lower than it should, as a rule because the line touches ground. Ford's 2024-25 summary pairs it with P2887_11, a short to ground, on the 8F24, 8F35/8F40 and 8F57 automatics; for the TR9070 dual-clutch unit it is called a shorted switch on the parking lock hold solenoid, meaning the switching side of the stage is pulled to ground. Chafed insulation where the harness passes brackets, moisture or corrosion in the connector and a coil shorted to its housing are typical finds. Some layouts would then energise the actuator permanently, others cannot switch it at all, so the controller blocks the function and warns the driver. Repairs start with resistance and insulation checks against ground, measured with the connector unplugged.

Repair estimate
