Typical Malfunction Thresholds
WARNING: This page is about a different car, the 2007 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
Case1: Mass airflow meter rationality (High voltage)
TYPICAL MALFUNCTION THRESHOLDS (CASE1) - MASS AIRFLOW METER RATIONALITY (HIGH VOLTAGE)
| Mass air flow meter voltage | More than 2.2 V (varies with throttle position) |
Case2: Mass air flow meter rationality (Low voltage)
TYPICAL MALFUNCTION THRESHOLDS (CASE2) - MASS AIRFLOW METER RATIONALITY (LOW VOLTAGE)
| Mass air flow meter voltage | Less than 0.7 V (varies with throttle position) |
