Oxygen Sensor

Disconnect oxygen sensor wire from harness connector attached to bracket, near valve cover(s). Start and warm engine to normal operating temperature. Measure voltage between oxygen sensor connector and ground. Voltage should be greater than .6 volt at 5000 RPM, and less than .4 volt when throttle is released quickly. If not as specified, replace oxygen sensor.
