Confusing Scanner Readings
1996 LT1
My new scanner arrived today and I had to hurry up and give it a try.
Okay: No stored Check Engine code.
I was able to monitor in real-time: RPM, coolant temp, 02 activity, fuel, MAP activity, etc., etc. but NO MAF or IAC percentage.
Wouldn't a bad MAF and/or IAC throw a code? I'm assuming that because there was no reading one or both of them is down for the count.
I can see, now, that I'm going to have to buy another Volume 2 FSM.
Thanks,
Jake

I've seen something similar on an Auto-X Ray scanner before and it turned out it was configured for the wrong year car. Something simple to check just in case! I have an Actron scanner for mine and it will read both the flow rate of the MAF and the step count for the IAC.

Thanks for that.
I just checked the resistance on my IAC connector and they fell within the 40-80 ohm range.
I don't know of any other way to see if that sucka is ACTUALLY working or not. Even after I solve this one mystery I've still got to find out why I'm not getting a MAF reading.
Where in the HELL did I put my FSM??????
