Check

PERFORMANCE ORDER

1. To check the sensor EGR valve, disconnect the connector connecting the valve (arrow) and check the resistance between terminals 1 and 3, 3 and 5, 4 and 2, 4 and 6 on the valve. It should be approximately 22 ohms. If not, replace the valve. 2. Warm up the engine to normal operating temperature. Disconnect the vacuum hose from the valve and connect the vacuum pump. When you create a vacuum engine performance should deteriorate or he may even die. If not, replace the valve. 3. Check that the solenoid valve to change the direction of air flow when voltage is applied.

Recirculation Valve Replacement

PERFORMANCE ORDER

1. Disconnect the connection of the valve. Remove the tube recycling, turn off fixing bolts (are specified by arrows) and remove the valve. 2. Installation is spent upside-down removals. Use a new gasket.
