Check current data.
A.
Specification : Refer to service 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.
The purpose of the Inspection is to analyze whether the cause of irregular hesitation is fuel system or intake/exhaust system. When air-fuel mixture is lean due to the problem of fuel system, ISCA is opened for target RPM. And therefore MAF data rises due to intake air flow is increasesd. In case of faulty intake/exhaust system such as leakage of vacuum or blocked intake/exhaust, MAF value is decreased.
Engine "ON" and warm up the engine until cooling fan is operated.
Connect a scanner to Data Link Connector (DLC).

Is current data normal?
When current data is similar to [Fig.3],
Go to "Fuel system inspection" procedure.
When current data is similar to [Fig.4],
Go to "Intake/exhaust system inspection" procedure.
