Unlocking the Secrets of Normal Sensor Readings For Optimal Performance

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. It will read very rich almost all the time in around the 0.845v range give or take a little but then if you just let it sit it will drop down to 0.1v or below ... The MAF readings seem choppy as RPMs increase under load. Not sure if this is normal or not, but I'm chasing a performance issue during acceleration at low ... The mV values are just the O2 reading based on rich/lean conditions. Most people recommend replacing them at every 50K regardless. I believe stoichometric is ... The computer recognizes the sensor as hot and active once there are several cross counts. You are looking for voltage to go above and below 0.45 ... Oxygen sensors will run from almost 0 volts up to around 1.1 volt. I'm not sure why it's reading over 2 volts, but some aftermarket diagnostic tools can be a ... If you remove it and look at the element, it's a platinum RTD, mounted on arms, which feed the circuitry. I have read somewhere that the MAF ... Typical maf readings on any car is between 2 and 7 at idle higher than that indicates an issue but is relative to rpm. The higher the rpm the ... My MAP pressure is around 11 in/hg at idle. Not sure if that's right or not, but my car is running super lean. O2 Sensor Readings ... P0420 appeared this summer. Fixed leaking flex pipe, but code comes back with every highway drive. 3.2L with 100K. Gas ...
