Operation

Power is supplied to the EGR vacuum regulator from the Battery Junction Box. The PCM controls the solenoid in the EVR with alternating shorts and opens to generate a rectangular waveform (on/off) electrical current that flows thru the EVR. The duty cycle (time on vs time off) of the waveform is transduced to a corresponding opening and closing of the vacuum valve in the EVR.削除

An electrical current that corresponds to the static pressure difference in the exhaust before and after the orifice is output by the DPFE and routed to the PCM where it is sensed as a voltage.削除

EVR Testing

Check fuse 13 (15 amps) in the battery junction box. Disconnect the EVR electrical connector and connect the positive probe of a voltmeter to the light blue/orange wire or pin. Connect the negative probe of the voltmeter to ground. Turn the ignition switch to On and check the meter for battery voltage. Turn the ignition switch off. Disconnect the probe from the light blue/orange wire and reconnect the EVR electrical connector.削除

Disconnect the DPFE electrical connector and connect the positive probe of a multimeter to the brown/white wire or pin. Connect the negative probe of the multimeter to the gray/red wire or pin. Turn the ignition switch to On and check the meter for 4.0 to 6.0 volts. Turn the ignition switch off.削除

Disconnect the meter probe from the brown/white wire of the DPFE and connect the probe to the gray/red wire connected to the TPS. Set the multimeter to ohms and check for less than 1.0 ohm. Remove the meter probes and reconnect the DPFE electrical connector.削除
