Possible cause |
| P0101 |
Mass air flow sensor (bank 1) circuit range/performance |
- A high voltage from the sensor is sent to ECM under light load driving condition.
- A low voltage from the sensor is sent to ECM under heavy load driving condition.
|
- Harness or connectors (The sensor circuit is open or shorted.)
- Mass air flow sensor (bank 1)
- EVAP control system pressure sensor
- Intake air leaks
- Intake air temperature sensor
|
| P010B |
Mass air flow sensor (bank 2) circuit range/performance |
- Harness or connectors (The sensor circuit is open or shorted.)
- Mass air flow sensor (bank 2)
- EVAP control system pressure sensor
- Intake air leaks
- Intake air temperature sensor
