Monitor Description

If there is a defect in the MAF meter or an open or short circuit, the voltage level deviates from the normal operating range. The ECM interprets this deviation as a malfunction in the MAF meter and sets a DTC.

• Example:
  • When the sensor output voltage remains less than 0.2 V, or more than 4.9 V for 3 seconds, the ECM sets a DTC.
