– Leave the EGR valve connected.
– Connect a "wire clip" to the violet wire between the valve and the injection computer (connection
between track 6 of the valve and track J2 of the injection computer connector B).
– Connect the positive terminal of the voltmeter to the wire clip.
– Connect the negative terminal of the voltmeter to the battery earth.
– Run command AC002 EGR solenoid valve.
– The voltage should vary over 10 cycles between 1.05 V and 3.5 V.
– If the voltage varies between these values, replace the EGR valve.
– If the voltage does not vary or varies between incorrect values, contact the Techline.
