O2 sensor test. 700

posted by  someone claiming to be zvolvo on  Fri Mar 28 05:24 CST 2008 [RELATED]

sorry for the confusion.both the 940 and 740 have the regina system.the black
wire from the O2 is connected to the Green wire in the car harness(and thats what i was refering to).i have the 740 for 3 years now,i never changed the O2.
i am using a voltmeter so the fluctuation is fast but not sure I need to use
an asciloscope but do have one.my main concern is why there is no change in the reading when i pull the vaccum to the fpr and also when i cause a vaccum leake in the system.thanks
