What wires do you use to monitor the o2 sensor to the multimeter??? Also whats the target range??? Thanks..

You didn't say which o2 sensor.

Put the meter on volts, hook the red lead to the black O2 wire, ground the other meter wire. Shoot for a reading in the mid to high .8 volt range.

Modes of operation (O2 gauge)


1. Key on, engine off; 1 bar or less (duh)! (unless you have a voltage leakage problem in your wiring)

2. Engine running first 1-3 minutes; bar will slowly climb to 9-10 bars (.9 to 1.0 volts) after the computer sees .9 volts, it will start O2 feedback. If it's VERY cold out it will not begin O2 feedback till the engine warms up a bit regardless what the O2 sensor is reading.

3. Engine at normal operating temp; at cruise bouncing up and down fairly quickly. At idle will be about the same, maybe a shade slower.

4. 3/4 throttle, normal temp, 4-7psi/boost; will rise to 6-8 bars (.6 to .8 volts), no bounce.

5. WIDE OPEN THROTTLE!, any temp, 1-14psi/boost; 9-10 bars (.9 volts), no bounce.

hmm thats 1-14 psi though..does it matter??

You don't tell us anything about the car or boost level or anything.

And I'm not posting that link for fun, read it and try to understand what Gary meant.

Kyle... you are looking for at least .88v @ wot. At wot the car is in self protection mode... LOL. Part throttle and WOT fueling tables are entirely different.
