Oxygen Sensor
- Warm engine to normal operating temperature. Connect voltmeter to service connector (Green connector behind right strut tower). Connect positive testing to Ox terminal and negative testing probe to terminal E. See Fig 1.
- Run engine at 2500 RPM. Check that voltmeter fluctuates 8 times or more in 10 seconds with 0-6 volts. If so, oxygen sensor is okay. If not, inspect other parts, hose connections and carburetor feedback system wiring. If no problems with these are found, replace oxygen sensor.
