With Manual Transaxle

Using the Special Service Tool (Engine Signal Monitor)

Special Service Tool (Engine Signal Monitor):

EGR Valve Position Sensor Testing With Vacuum Pump:

1. Connect the SST to the Powertrain Control Module (PCM) as shown and connect a vacuum pump to the EGR valve.
2. Turn the ignition switch to ON.

EGR Valve Position Sensor Specifications:

3. Measure the voltage at the terminals as shown in the table.
4. If not correct at 3J terminal, check the wiring harness and 3J terminal of the PCM.

Special Service Tool New Generation Star Tester Connected to Data Link Connector 2:

Using the SST (NGS)
1. Connect the SST New Generation Star (NGS) tester to the data link connector 2.

NGS Display:

2. Select the "PID/DATA MONITOR AND RECORD" function of NGS and connect a vacuum pump.
3. Select "EGR on the NGS display. The NGS measures and shows the voltage.

EGR Valve Position Sensor Specifications:

4. If EGR valve position signal voltage is not as specified, check the wiring harness and 3J terminal of the PCM.

RESISTANCE TEST
1. Disconnect the EGR valve position sensor connector, and connect an ohmmeter.

EGR Valve Position Sensor Testing With Vacuum Pump:

2. Disconnect the vacuum hose from the EGR valve, and connect a vacuum pump.
3. Measure the resistance between the terminals as shown while vacuum is applied.

EGR Valve Position Sensor Specifications:

4. If not as specified, replace the EGR valve.
