P0814 Code - Transmission Range Display Circuit

What does P0814 Mean?

Now, clear the codes and test-drive the vehicle to see if the code is reset. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground. Oxygen sensors signal the engine management computer the amount of oxygen present in the exhaust, which is used in determining and controlling the fuel ratio.

What are the common causes of P0814 ?

By far the most common cause of this code is from a misadjusted transmission range sensor. Other causes may include a defective range sensor, open, shorted, corroded, or otherwise damaged wiring and/or electrical connectors. If recent transmission repairs have been performed, suspect that the range sensor was not readjusted properly. Sensor retaining bolts should always be installed using thread locking compound to ensure proper torque longevity. Technicians also report the presence of excessive corrosion in the sensor connector as the cause of this code being stored.



How do you troubleshoot P0814 ?

Some of the fixes for the P0814 trouble code are:

• Alignment of the transmission range sensor
• Replacement of wires, connectors, and circuits in the system
• Replacement of the range sensor connector
• Replacement of the range sensor
