Resistance Inspection
- Remove the battery cover.
- Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF] .)
- Disconnect the MAF/IAT sensor connector.
- Verify that the resistance between MAF/IAT 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/IAT sensor. (See MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION
