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
