This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has found a problem with a sensor that checks the pressure of the fluid in the transmission. It's like a thermometer for the car's transmission fluid, and it's not working right.
The P0987 code is triggered when the powertrain control module (PCM) detects an issue with the circuit of the transmission fluid pressure sensor or switch labeled 'E'.
The transmission fluid pressure sensor/switch monitors the hydraulic pressure in the transmission. This information is used by the PCM to control transmission operation. If the sensor or its circuit fails, the PCM cannot accurately control the transmission, leading to potential drivability issues.
• Transmission slipping
• Harsh shifting
• Illuminated check engine light
• Faulty transmission fluid pressure sensor/switch
• Damaged or corroded wiring/connectors
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission fluid pressure sensor/switch with a multimeter.
• Replace the transmission fluid pressure sensor/switch if faulty.
• Repair or replace damaged wiring/connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Honda Accord
• Regular transmission maintenance
• Timely fluid changes
• Routine inspection of wiring and connectors
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with the vehicle manufacturer for warranty coverage on transmission components.
The P0987 code has been a common issue in vehicles with electronic transmission controls, especially as they age.
Moderate – It should be addressed soon to avoid transmission damage.
Ignoring this code may lead to further transmission damage and potential safety issues.
• Engine running
• Transmission at operating temperature
The transmission fluid pressure sensor is typically located inside the transmission or on the transmission housing.
Q: Can I drive with a P0987 code?
A: It's not recommended to drive for extended periods with this code, as it may cause further transmission damage.
Q: How do I clear a P0987 code?
A: After fixing the issue, use an OBD-II scanner to clear the code from the PCM.
