p0848 transmission fluid pressure sensor switch b circuit high 2
P0848 Transmission Fluid Pressure Sensor Switch B Circuit High 2
Definition: This code indicates that the transmission control module (TCM) has detected a high voltage condition in the transmission fluid pressure sensor/switch “B” circuit.
p0848 – Transmission Fluid Pressure Sensor/Switch B Circuit High
Severity: Moderate
Common Causes
p0848 – Transmission Fluid Pressure Sensor/Switch B Circuit High
Common causes:
- Faulty transmission fluid pressure sensor/switch
- Short circuit or open circuit in the wiring related to the sensor/switch
- Low transmission fluid level or dirty transmission fluid
- Faulty transmission control module (TCM)
Common Misdiagnosis
OBD2 Code: P0848
Description: Transmission Fluid Pressure Sensor/Switch B Circuit High
Common Misdiagnosis: Replacing the transmission fluid pressure sensor/switch without checking for wiring issues or connector problems.
Common Diagnostic Steps
OBD2 Code: P0848
Description: Transmission Fluid Pressure Sensor/Switch B Circuit High
- 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 B circuit.
- Test the transmission fluid pressure sensor/switch using a multimeter to ensure it is functioning correctly.
- Examine the powertrain control module (PCM) for any software updates or known issues that might relate to this code.
- If applicable, use a scan tool to monitor live data from the transmission fluid pressure sensor/switch to check for irregular readings.
- Replace the transmission fluid pressure sensor/switch if found faulty after testing.
- If all else fails, consider consulting a professional technician for further diagnosis as internal transmission issues may be present.
