Resistance Inspection
- Disconnect the IAT sensor No.2 connector.
- Verify that the resistance between terminals A and B is within the specification.
- If not within the specification, replace the IAT sensor No.2. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION (BP WITH TC) .)
- If the monitor item condition/specification (reference) is not within the specification, even though there is no malfunction, perform the CIRCUIT OPEN/SHORT INSPECTION .
