Description

According to intake/exhaust system inspection engine hesitation is caused by PCSV. The purpose of the inspection is to check PCSV.

Diagnostic Procedure
PCSV Inspection(Vacuum leakage Inspection)
1.

IG "OFF"

2.

Disconnect the vacuum hose and install the vacuum gauge.

3.

Operate the vacuum gauge and check leakage of vacuum.

A.

Specification : Vacuum state maintains at operating vacuum gauge.

4.

Does vacuum gauge maintain vacuum value?

YES

Go to "PCSV Simulation test" procedure as below.

NO

Replace the PCSV.

PCSV Simulation test
5.

IG "ON"

6.

Connect a scantool to Data Link Connector (DLC).

7.

Perform actuation test using a scanner.

A.

Specification : Vacuum state released by actuation test.

8.

Is vacuum state released by actuation test?

YES

PCSV is OK.

NO

Replace the PCSV.

caution

■ Check the PCSV

■ Check the PCSV control duty waveform
