Description:

  • The fault code P0841 indicates that there is an issue with the range or performance of the transmission fluid pressure sensor/switch A circuit. This may cause the transmission to not shift properly or not engage at all.

Possible Symptoms:

  • Harsh shifting or delayed shifting

  • Transmission slipping or not engaging

  • Illuminated check engine light

  • Reduced fuel efficiency

Possible Causes:

  • Faulty transmission fluid pressure sensor/switch

  • Damaged wiring or connections in the circuit

  • Failed transmission control module (TCM)

  • Low transmission fluid level or poor quality fluid

Related Parts:

  • Transmission Fluid Pressure Sensor: Gear fluid line delivers gear fluid/oil between the various gear parts that need lubrication. The Gear fluid line pressure Sensor monitors the fluid pressure in the line. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Replace the transmission fluid pressure sensor/switch

  • Check and repair any damaged wiring or connections

  • Ensure the transmission fluid level and quality is appropriate

  • Replace the transmission control module (TCM) if necessary
