NOTE: Ensure that MAF sensor is not blocked, and that there are no vacuum leaks before performing test.

Connect scan tool to Data Link Connector (DLC). Start engine and allow it to reach normal operating temperature. Select MAF SENSOR FLOW RATE parameter on scan tool. See MAF SENSOR STANDARD VALUES table for specified values. If scan tool display is not as specified, replace MAF sensor and retest system.
