DTC P0069-21: MAP - Barometric Pressure Correlation - Signal amplitude < minimum: Action
- Using the manufacturer approved diagnostic system check datalogger signal - Manifold Absolute Pressure Sensor Voltage - (0x0301)
- Refer to the appropriate system wiring diagrams and check the manifold absolute pressure sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Check and install a new manifold absolute pressure sensor as required
- Check and install a new engine control module as required
