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