P0988

2017-10-10

Description:

  • The fault code P0988 indicates that there is an issue with the transmission fluid pressure sensor or switch E circuit, which has resulted in the circuit registering a high voltage. This may lead to transmission issues such as harsh shifting or failure to shift, and could also cause damage to other transmission components.

Possible Symptoms:

  • Harsh shifting or failure to shift

  • Illuminated check engine light

  • Transmission slipping

  • Reduced fuel efficiency

  • Overheating transmission

Possible Causes:

  • Failed transmission fluid pressure sensor or switch E

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed transmission control module (TCM)

Related Parts:

  • Hydraulic Pressure Sensor: Hydraulic oil is needed for the gear lubrication system. This sensor measures oil pressure. This car's sensor has a problem which may cause difficulty in shifting gears

Possible Solutions:

  • Replace the transmission fluid pressure sensor or switch E

  • Check and repair any damaged wiring or connections in the circuit

  • Tighten or clean any loose or corroded electrical connections

  • Replace the transmission control module (TCM) if necessary
