Typical Malfunction Thresholds
Mass Air Flow Meter Rationality (High Voltage):
MASS AIR FLOW METER VOLTAGE REFERENCE
| Mass air flow meter voltage | More than 2.2 V (varies with throttle position sensor voltage) |
Mass Air Flow Meter Rationality (Low Voltage):
MASS AIR FLOW METER VOLTAGE REFERENCE
| Mass air flow meter voltage | Less than 0.73 V (varies with throttle position sensor voltage) |
