The purpose of the Inspection is to analyze whether the cause of the engine hesitation when load is applied is due to fuel system, ignition system or intake/exhaust system. To analyze the cause of engine hesitation, Using the tendency of HO2 sensor waveform with stall test of the "D" range.

3.

Analyze the cause of engine hesitation by stall test of the "D" range.

A.

Specification : Refer to current data as below.

caution

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

B.

When current data measured similar to [Fig1],

Go to "fuel system Inspection" procedure.

C.

When current data measured similar to [Fig2],

Go to "Intake/exhaust system Inspection" procedure.
