INTAKE-AIR SYSTEM MANIFOLD VACUUM INSPECTION1. Verify that the intake-air system related parts and hoses are securely installed.
2. Remove the intake manifold blind cap and install the vacuum gauge.
3. Warm up the engine.
4. Measure intake manifold vacuum while no load and Idling.
Intake manifold vacuum
MT: -66.7- -56.0- kPa {-500.2- -420.1 mmHg, -19.7- -16.5 inHg}
4-speed AT [RC4A-EL]: -67.3- -53.4 kPa{-504.7--400.6 mmHg, -19.9- -15.7 inHg}
6-speed AT [SJ6A-EL]: -66.9- -53.1 kPa {-501.8- -398.3 mmHg, -19.7- -15.6 inHg}
- If not within the specification, perform the following inspection:
- Compression pressure (See Compression Inspection.)
- Air intake
- Each hose installation part
- Throttle body installation part
- Fuel injector installation parts
- Extension manifold (upper, lower) installation part
- Purge solenoid valve installation part
- Intake manifold installation part
