DTC P0101-22: Mass or Volume Air Flow A Circuit Range/Performance - Signal amplitude > maximum: Action
- Using the manufacturer approved diagnostic system check datalogger signal - Mass Air Flow Sensor Frequency - (0x033D)
- Using the manufacturer approved diagnostic system check datalogger signal - Air Flow Rate from Mass Air Flow Sensor - (0xF410)
- Check mass air flow sensor connector is correctly latched
- Refer to the appropriate system wiring diagrams and check power feed to mass air flow sensor for open circuit
- Refer to the appropriate system wiring diagrams and check the mass air flow sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Check and install a new mass air flow sensor as required
