Empowering Engineers with Normal Sensor Reading Mastery

One which is pre-cat was about 1.5 (up to 2) volts on idle. I've been told that lambda probes should not give more than 1 volt, so I've decided ... Normal Fuel trim Oxygen O2 sensor values NA Engine (non-turbo) / Drivetrain / Exhaust Modifications. 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. The 950 when WOT may be a little high, but that's based on your tune. The jumping around while normal driving is completely normal. That's the way it's ... 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. I picked up a bluetooth doohickey and Torque app, and I noticed that on my 1996 3.4 automatic, my O2 Bank 1 Sensor 1 is reading between .3V and ... At normal driving you should see a steady voltage around 600-800mV most of the time. You'll see lower during fuel cut (idle deceleration) and ... the traditional B1 S2 sensor. The rear sensor, S2, reports voltage in the manner you described. The front sensor, S1, can report in several ... 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 ... As a forme ASE certified automotive technician, this is the best simple explanation I have seen in a very long time.
