Repair Procedures: Inspection
System Inspection
- Disconnect the vapor hose from the throttle body and connect a vacuum pump to the nipple on the throttle body.
- Check the following points with applied vacuum using a vacuum pump.
- At Cold Engine (Engine Coolant Temperature < 60°C (140°F))
SYSTEM INSPECTION - COLD ENGINE
| Engine Operating Condition | Applied Vacuum | Result |
|---|---|---|
| Idle | 0.5kgf/cm2 (50 kPa, 7.3 psi) | Vacuum is held |
| 3, 000 RPM |
- At Warmed Engine (Engine Coolant Temperature > 80°C (176°F))
SYSTEM INSPECTION - WARMED ENGINE
| Engine Operating Condition | Applied Vacuum | Result |
|---|---|---|
| Idle | 0.5kgf/cm2 (50 kPa, 7.3 psi) | Vacuum is held |
| Within 3 minutes after engine start at 3, 000 RPM | Try to apply vacuum | Vacuum is released |
| In 3 minutes after engine start at 3, 000 RPM | 0.5kgf/cm2 (50 kPa, 7.3 psi) | Vacuum will be held momentarily, after which, it will be released |
PCSV Inspection
- Turn ignition switch OFF and disconnect the negative (-) battery cable.
- Disconnect the PCSV connector (A).
- Disconnect the vapor hose (B) which is connected to the intake manifold from the PCSV.
1.6 DOHC
2.0 DOHC
- After connecting a vacuum pump to the nipple, apply vacuum.
- With the PCSV control line grounded, check the valve operation with battery voltage applied to the PCSV (Open) and removed (Closed).VALVE OPERATION CHART
Battery Voltage Valve Vacuum Connected Open Released Disconnected Close Maintained - Measure the coil resistance of the PCSV.
