DTC Description

The PCM compares the airmeter input frequency to low and high limits. When the frequency is outside the allowable limits, the circuit is determined to be failed.

If PCM detects that frequency signal of MAFS is higher than 11900 Hz for more than 75 second failure during 125 second diagnostic test while enable condition is met PCM determines that a fault exists and a DTC is stored. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
