With Automatic Transaxle

Using the Special Service Tool (104 Pin Breakout Box)
1. Warm up the engine to normal operating temperature.




2. Connect the SST to the Powertrain Control Module (PCM).
3. Measure the voltage at PCM terminals 35 and 60.




4. If not as specified, inspect the following.
- Fuel system
- On-board diagnostic system
- Intake-air system

5. If all the systems are OK, replace the heated oxygen sensor.

Using the SST (NGS)




1. Connect the SSTs to the data link connector-2.




2. Select the "PID/DATA MONITOR AND RECORD" function of the New Generation Star (NGS) tester.
3. Select the "025 11", "025 12" on the NGS. The NGS measures and shows the voltage.




4. If not as specified, inspect the following.
- Fuel system
- On-board diagnostic system
- Intake-air system
5. If all the systems are OK, replace the heated oxygen sensor.

Heater Testing







1. Disconnect the heated oxygen sensor connector.
2. Measure the resistance between heated oxygen sensor terminals C and D by using an ohmmeter.

Specification: Approx. 6 Ohms 20°C (68°F)

3. If not as specified, replace the heated oxygen sensor.
