Resistance Inspection
- Disconnect the mass air flow sensor connector.
- Verify that the resistance between MAF sensor terminals D and E is within the specification.
- If the monitor item status/specification (reference) is not within the specification, even though the IAT sensor resistance is within the specification, perform the "CIRCUIT OPEN/SHORT INSPECTION ".
- If not within the specification, replace the MAF sensor.
