EGR Control Solenoid Valve (California)
- Mark vacuum hoses for installation reference. Disconnect Yellow and Green-striped vacuum hose from EGR control solenoid valve.
- Disconnect EGR control solenoid valve electrical connector. Connect a hand-held vacuum pump where Green-striped vacuum hose was connected. Apply battery voltage to EGR solenoid valve terminals.
- Apply vacuum with hand-held vacuum pump. When battery voltage is applied, vacuum should hold. When battery voltage is disconnected, vacuum should not hold.
- Disconnect battery voltage. Using an ohmmeter, check EGR control solenoid valve resistance. Resistance should be 36-44 ohms at 68°F (20°C). Replace EGR control solenoid valve if it does not test as described.
