Optimizing Performance with Normal Sensor Readings

They can be anywhere from .2v to .9v, but usually between .4v and .8v. Is this normal? The second O2 sensor readings are much more stable. 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 ... When I was graphing the front O2 sensor the voltage readings were steady around 18000. ... Was car already at/past normal operating temp (ramp-up)?. 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 ... Normal Fuel trim Oxygen O2 sensor values NA Engine (non-turbo) / Drivetrain / Exhaust Modifications. Generally speaking, yes. Conventional O2's in an upstream position will switch. Downstream sensors will USUALLY hang around 600-800mV if the catalyst is ... Per the tech manual it's 2.5 to 5.0 g/sec at idle and 7.1 to 12.5 g/sec at 2500 rpm. So my MAF sensor is working about right. My O2 sensors also both seem to ... ambient, which will be over 22 in hg pressure. Idle MAP reading is going to be around 10 in hg pressure. If your scanner is converting it to a ... 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. The PD motors must have this type of sensor. The voltage readings with my scan tool are very precise. The voltage readings will move around in very small ...
