What I'm talking about is, say, the O2 sensors as an example. What should the reading on a live data scan tool be if they are good? The TAC, TPS, MAP, MAF...Stuff like that. I've done a Google and must be using the wrong search terms or some such idiocy. I've got the scan tool, but don't know what the info should be so it does me not much good. Thanks

- fuel trims (which are based on O2) should be close to zero %
- TPS should be a few percent at idle, and close to 100% with the pedal floored
- logically , MAP should match atmospheric pressure a WOT since there's little restriction, and will be less (vacuum) at idle. Lowest while engine braking. The value depends on engine load and throttle position.
- MAF rule of thumb is 1g/s per litre of displacement at idle, and rises with throttle position.
- I don't know what TAC is.
Thanks for the reply. TAC= Throttle Actuator Control. My O2(s) are running, at idle, engine cold,
B1 S1 .09-.78 FLUCTUATING
B1 S2 .74 STEADY
B2 S1 .095-.80 FLUC
B2 ST .685-.72 FLUC
Those are voltage reading.
I just recvd a BlueDriver in the mail today and will try that one tomorrow.
