Unleashing the Power of Normal Sensor Readings

As far as I understand it, the only type of vehicle that is going to have a steady reading when you read the output of the O2 sensor is if you ... When the air/fuel ratio is perfect and the fuel mixture is 14.7:1 (stoichiometric), the sensor will generate approximately 0.45 volts. This is ... Bearing in mind the readings will fluctuate between 0.1V - 0.9V every second, which is roughly 1 Hz, I noticed something peculiar about bank 1. 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. It's the ECU responding to changes from the O2 sensor that you see taking place. I found out about 15 years ago that as they get old they become lazy and the ... In answer to your question 4.2 to 6 is correct MAF reading for warmed up idle, remember it's calculated PCM looks at IAT and MAS (sensor ... Ever since I've owned the car its also felt sluggish compared to my 2010 318D. Does anyone know if this MAF reading is normal? Thanks! Sam. Second, normal readings at sea level are 8-12". At higher altitudes, expect 14-18". Before you buy a new part, check for vacuum leaks. An ... 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 ... Hey I was just wondering what normal voltage should be for o2 sensors mine seem a bit low. Downstreams tend to hang below .4v usually around ...
