The P0069 trouble code indicates a correlation problem between the manifold absolute pressure (MAP) sensor and the barometric pressure sensor. This code typically points to an issue with the relationship between the two sensors, affecting the engine’s performance.
Manifold Absolute Pressure – Barometric Pressure Correlation
Code symptoms P0069.
1. Reduced engine performance.
2. Rough idling or stalling.
3. Poor fuel efficiency.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P0069.
1. Faulty MAP sensor or barometric pressure sensor.
2. Wiring or connector issues within the sensor circuit.
3. Problems with the Engine Control Module (ECM).
Code Solutions P0069.
1. Inspect and replace the MAP sensor or barometric pressure sensor if any are found to be faulty.
2. Check and repair any damaged wiring or connectors in the sensor circuit.
3. If ECM issues are suspected, consult a qualified technician for diagnosis and potential reprogramming or replacement.
