Laymans terms

This code means that the car's computer is having trouble reading the position of the gear lever because the sensor is not working properly all the time.

Explanation

The P089E code is triggered when the transmission control module (TCM) detects an intermittent or erratic signal from the gear lever position sensor 2. This sensor helps the car know what gear the driver wants to use.

Technical description

The gear lever position sensor 2 is responsible for sending the position of the gear lever to the TCM. If the sensor sends inconsistent or erratic signals, the TCM may not be able to determine the correct gear position, leading to potential transmission issues.

Symptoms

• Check Engine Light illuminated

• Transmission may not shift properly

• Erratic gear selection

Common Causes

• Faulty gear lever position sensor

• Wiring issues such as frayed or damaged wires

• Poor electrical connections in the sensor circuit
