Unlocking the Potential of Normal Sensor Readings

Notice things like MAP, MAF, ECT, IAT, and even HO2S (Oxygen Sensor). The MAP should read between 95-105 in most cases, your MAF should read ... With the engine at normal temp (80-100C) and airbox in place, VERY rough readings should be: Idle rpm = 20 kg/hr 1000rpm = 30kg O2 sensors should cycle continuously between 0.2v to 0.8v and back to 0.2v about once per second. 2.67v isnt right. Could be a vacuum leak, ... When I often see a more or less constant reading on those tools, I expect the DME to be upset, yet it often isn't. I expect to see readings ... To get the proper voltage from an OBDII scanner, take the value read and multiply it by 5. For example, if your B1S1 O2 sensor reading is .3V, ... All the O2 voltages over 1 volt are off-scale high (rich). While in closed loop mode, both sensor 1 voltages should be oscillating from around . The map sensor should be reading 16 to 20 in hg. What makes you suspect a lean condition? Normally a MAP sensor compensates for vacuum leaks. 110-145 is generally considered a normal range. For both of the fuel trim multipliers: A count below 128 is a lean command which means the ... 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 ... I'm having problems with my map sensor It's reading low. My map sensor reads 26 in hg and baro reading 29 in hg key on engine off.
