P0990 Transmission Fluid Pressure Sensor Switch E Circuit High 2
- OBD2 Code: P0990
- Description: Transmission Fluid Pressure Sensor/Switch E Circuit High
- Definition: This code indicates that the transmission control module (TCM) has detected a high voltage condition in the transmission fluid pressure sensor/switch circuit for sensor E.
p0990 – Transmission Fluid Pressure Sensor/Switch E Circuit High
Typical Severity: Moderate
Common Causes
P0990 – Transmission Fluid Pressure Sensor/Switch E Circuit High
Common causes include:
- Faulty transmission fluid pressure sensor/switch
- Short circuit or open circuit in the wiring connected to the sensor/switch
- Low transmission fluid level or dirty transmission fluid
- Faulty transmission control module (TCM)
Common Misdiagnosis
OBD2 Code: P0990
Description: Transmission Fluid Pressure Sensor/Switch E Circuit High
Common Misdiagnosis: Replacing the transmission fluid pressure sensor/switch without checking for wiring issues or connector problems.
Common Diagnostic Steps
OBD2 Code: P0990
Description: Transmission Fluid Pressure Sensor/Switch E Circuit High
- Check the transmission fluid level and condition.
- Inspect the wiring and connectors for damage or corrosion.
- Test the transmission fluid pressure sensor/switch for proper operation.
- Verify the integrity of the circuit by checking for continuity and shorts.
- Use a scan tool to monitor live data from the transmission fluid pressure sensor/switch.
- If necessary, replace the faulty transmission fluid pressure sensor/switch.
- Clear the code and test drive to ensure it does not return.
