The purpose of the inspection is to analyze poor power/acceleration after checking MAFS current data measured at various loading condition.
Engine "ON" and allow the engine to warm up to normal operating temperature.
Connect a scantool to Data Link Connector (DLC).
Check current data.
This current data is nothing but an example at certain condition. Thus, the real current data and waveform could different from this example.
Is current data within specification ?
YES
MAF sensor is OK.
NO
Check the related harness or Replace the MAF sensor.
