2017-10-10

Description:

  • Up and Down Shift Switch to Transmission Range Correlation

Possible Symptoms:

  • Test and replace the faulty up and down shift switch, if necessary

  • Test and replace the faulty transmission range sensor, if necessary

  • Inspect and repair the wiring or connection problems between the switch and sensor

  • Ensure the connectors in the transmission system are secure and free from corrosion

  • Test the transmission control module (TCM) for proper functionality and replace it if necessary

Possible Causes:

  • The fault code P0819 indicates a correlation problem between the up and down shift switch and the transmission range. This fault code typically points to an issue with the communication or synchronization between the up and down shift switch and the transmission range selection.

Related Parts:

  • Transmission Shift Sensor: Gear Shift Sensor communicates the position the gear shifted to. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Faulty up and down shift switch

  • Faulty transmission range sensor

  • Wiring or connection problems between the switch and sensor

  • Loose or corroded connectors in the transmission system

  • Faulty transmission control module (TCM)
