Description

The purpose of the inspection is to analyze poor power/acceleration after checking MAF current data in various vehicle condition and load condition.

Diagnostic Procedure
1.

Engine "ON" and warm up the engine until cooling fan is operated.

2.

Connect a scanner to Data Link Connector (DLC).

3.

Check current data.

A.

Specification :

Idle : Approx. 0.62V (12.0 kg/h)

Stall test in D Range : Approx. 3.3V

caution

This current data is nothing but an example at certain condition. Thus, the real current data and waveform could different from this example.

4.

Is MAFS current data normal?

YES

MAFS is OK.

NO

Check the related harness or Replace the MAF sensor.
