P0987 code indicates a problem with the transmission fluid pressure sensor or switch “E” circuit.
P0987 Transmission Fluid Pressure Sensor/Switch “E” Circuit
Code symptoms P0987.
1. Transmission slipping
2. Delayed engagement when shifting
3. Harsh shifting between gears
4. Illuminated check engine light
Causes of the code P0987.
1. Faulty transmission fluid pressure sensor or switch “E”
2. Wiring issues such as open circuits or short circuits in the sensor wiring
3. Poor electrical connection at the sensor or switch “E”
4. Low transmission fluid level or dirty or contaminated transmission fluid
5. Internal transmission issues such as a faulty transmission control module (TCM) or pressure control solenoid.
Code Solutions P0987.
1. Check the wiring harness connection to the transmission fluid pressure sensor or switch “E” for any damage, corrosion, or loose connections. Repair or replace as needed.
2. Inspect the transmission fluid pressure sensor or switch “E” for any signs of damage or malfunction. Replace the sensor if it is faulty.
3. Check the transmission fluid level and condition. If the fluid is low or contaminated, top up or perform a fluid flush and refill.
4. Clear the trouble codes using a diagnostic scan tool and perform a test drive to see if the P0987 code reappears. If it does, further diagnosis may be required.
5. Check the transmission control module for any fault codes related to the pressure sensor or switch circuit. Address any additional codes that may be present to ensure a complete repair.
