Resistance Inspection: Notes
- Disconnect the MAF/IAT sensor connector.
- Measure the resistance between MAF/IAT sensor terminals A and F.
- If not within the specification, replace the MAF/IAT sensor. (See MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION .)
- If the monitor item status/specification (reference) is not within the specification, even though the resistance is within the specification, perform the "Circuit Open/Short Inspection".
