O2 Sensor Test Point 700 1990

posted by  someone claiming to be Mark C, formerly Mark on  Wed Aug 15 06:56 CST 2001 [RELATED]

Does the '90 B230F/REX engine have a test connector to check oxygen sensor operation? If so, where is it and what does it look like? I saw a comment for an older model referencing a test connector near the airbox where an LED in series with a resistor could be connected to blink as the O2 sensor toggles between rich and lean mixture. Thanks
