DTC codes / P08xx · Transmission / P089E
P089E indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the gear lever position sensor 2 circuit, which is used to confirm the selected gear range. The PCM sets this code when the sensor voltage momentarily drops out or jumps outside the expected range, often due to a loose connection or failing sensor.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
