P0823: Gear Lever X Position Circuit Intermittent OBD-II Trouble Code

How Serious is the Code?

In order to operate properly, your vehicle has to know that the correct gear has been selected with the shifter. If there’s an intermittent problem with the sensor data that tells it what gear has been selected, compared to the current driving situation, a P0823 diagnostic trouble code will be triggered. And it can impact driving performance if that ECU thinks that you have selected the wrong gear.

Symptoms

Symptoms of a P0823 include:

  • Shifts are extremely harsh
  • Transmission gets stuck in a gear

Causes

  • Frayed/damaged wiring
  • Broken and/or corroded connectors
  • Misadjusted transmission range sensor

How to Diagnose the Code?

In order to determine what is causing a P0823 OBDII trouble code, your technician should first check the condition of the wiring and connectors going to the transmission range sensor. If everything looks good, and the sensor does not need to be adjusted, it should be tested to ensure that it works properly.
