Unleash the Power of Normal Sensor Readings A Comprehensive Guide

I swapped out MAP sensors just to see what it would show, stock one was at 28.1HG and the 'new' one was at 27.7HG. 1996 Pontiac Firebird - 3.8L, ... Actual grams per second, voltage or frequency readings should come from the MAF signal data on the scan tool at specified rpm settings. Example 1. A good MAF ... I expect to see readings varying from ~0.1V, to 0.9V, but they often don't get even close to that, even when the sensor voltage actually is ... Also, what are the unit for the values given? That is important. ... MAP normal range is 29-48 kPa, or 1-2 volts depending on engine load and ... I am getting polar opposite air/fuel readings between the two banks. Bank 1 is read high mV and bank 2 is reading ridiculously low mV. Was expecting the air flow readings to be the same for each bank. Should they be the same and, if so, what would a normal reading at idle be? So the bottom line is that the pre-cat O2 sensors should oscillate between about 0.2 to 0.8 volts regularly (about every 1 second at idle) in a ... The normal readings are 18 to 19 in. There must be some issue with the source vacuum or a voltage drop to the required circuits for that sensor to work. The wave form looks normal. It is averaging the fuel mix, and not stuck rich or lean. Did you install aftermarket cat, possibly a higher restriction. I have a basic Instrument to see OBDII data, but fuel trims were close to 0, it looks like maf values sent to the ecm are normal. Next Saturday ...
