p0987 transmission fluid pressure sensor switch e circuit 2
P0987 Transmission Fluid Pressure Sensor Switch E Circuit 2
Definition: This OBD-II code indicates a problem with the transmission fluid pressure sensor/switch “E” circuit. The powertrain control module (PCM) has detected an issue in the electrical circuit of this specific sensor or switch, which is responsible for monitoring the hydraulic pressure inside the transmission.
p0987 – Transmission Fluid Pressure Sensor/Switch E Circuit 2
Severity: Moderate
Common Causes
P0987 – Transmission Fluid Pressure Sensor/Switch E Circuit 2
Description: The Transmission Fluid Pressure Sensor/Switch E Circuit is indicating a low voltage condition.
Common Causes:
- Faulty transmission fluid pressure sensor/switch
- Wiring issues such as short circuits or open circuits
- Low transmission fluid level
- Dirty or contaminated transmission fluid
- Faulty transmission control module (TCM)
Common Misdiagnosis
OBD2 Code: P0987
Description: Transmission Fluid Pressure Sensor/Switch E Circuit 2
Common Misdiagnosis: Replacing the transmission fluid pressure sensor/switch without checking for wiring issues or connector problems.
Common Diagnostic Steps
OBD2 Code: P0987
Description: Transmission Fluid Pressure Sensor/Switch E Circuit 2
- Check the transmission fluid level and condition. Ensure it is at the correct level and not contaminated.
- Inspect the wiring and connectors for damage, corrosion, or disconnection related to the transmission fluid pressure sensor/switch E circuit.
- Test the voltage and ground signals at the transmission fluid pressure sensor/switch using a multimeter to ensure they are within specifications.
- Use an OBD2 scanner to clear the code and perform a test drive to see if it returns.
- If applicable, replace or repair any damaged wiring or connectors found during inspection.
- If all else fails, consider replacing the transmission fluid pressure sensor/switch after verifying that all other components are functioning correctly.
