Manuals through 2025 now available!

Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

With Automatic Transaxle

EGR VALVE POSITION SENSOR
Inspection of output voltage Using the SST (104 Pin Breakout Box)

SST (104 Pin Breakout Box):




Vacuum Pump On EGR Valve:




1. Connect the Special Service Tools (SST)s to the Powertrain Control Module (PCM) as shown and connect a vacuum pump to the EGR valve.
2. Turn the ignition switch to ON.
3. Measure the voltage at the terminals as shown in the table.




4. If not correct at 65 terminal, check the wiring harness and 90 terminal of the PCM.

Using the SST (NGS)

NGS:




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




2. Select the PID/DATA MONITOR AND RECORD" function of NGS and connect a vacuum pump.
3. Select EGR valve position sensor on the NGS. The NGS measures and shown in the specification.




4. If not correct EGR valve position signal voltage, check the wiring harness and 90 terminal of the PCM.

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

Vacuum Pump On EGR Valve:




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.




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