P0876: Transmission Fluid Pressure Sensor/Switch D Circuit Range/Performance — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
Transmission Fluid Pressure Sensor/Switch D Circuit Range/Performance. Basic catalogue definition; diagnostic details have not yet been reviewed.
Affected system: Powertrain
Symptoms
- The transmission has detected a range/performance anomaly from fluid-pressure sensor D.
- A warning, delayed gear changes or a protective transmission mode may occur.
Possible causes
- A failing sensor, damaged wiring or poor contacts can distort pressure feedback.
- Fluid condition or a hydraulic-pressure fault may also influence the monitored response.
What to check
- Read the fault and sensor data while noting operating conditions.
- Inspect sensor wiring, then check fluid and compare the reading with manufacturer pressure limits.
Also written as: P0876-00, P087600, PO876 (some scan tools add the fault-type byte, e.g. -00).
