Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC Description
If the PCM detects that the frequency signal of the MAFS is lower than 1000 Hz for more than 75 seconds during one diagnostic test (125 seconds), while Enable Conditions (shown in DTC DETECTING CONDITION CHART) are met, the PCM determines that a fault exists and a DTC is stored.
The MIL (Malfunction Indication Lamp) turns on when the malfunction lasts for 2 consecutive driving cycles.
