When you put your vehicle into gear, a number of sensors tell the engine computer how to set up the engine for the anticipated drive. If the ECU thinks that you have selected the wrong gear for the situation, a P0822 DTC will set.
How Serious is the Code?
While it might not seem like a very big deal, a P0822 diagnostic trouble code can actually affect the drivability of your vehicle, if the ECU thinks that you’re in the wrong gear.
Symptoms of a P0822 include:
- Unusually hard gear changes
- Transmission fails to shift
- Wiring damage
- Corroded/broken connectors
- Transmission range sensor needs to be adjusted
- Transmission range sensor has failed
How to Diagnose the Code?
The first thing that a mechanic should do when trying to diagnose a P0822 OBDII trouble code, is to check the condition of the wiring and connectors on the transmission range sensor circuit. If there are no electrical problems, and the transmission range sensor does not need to be adjusted, then the sensor may need to be replaced.
