2017-10-10

Description:

  • The fault code P0848 indicates that there is an issue with the circuit that controls the transmission fluid pressure sensor/switch 'B'. This may cause the transmission to shift irregularly or not shift at all.

Possible Symptoms:

  • Transmission shifts irregularly or not at all

  • Illuminated check engine light

  • Harsh or delayed shifting

  • Reduced fuel efficiency

Possible Causes:

  • Faulty transmission fluid pressure sensor/switch 'B'

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed engine control module (ECM)

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 'B'

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections

  • Replace the engine control module (ECM) if necessary
