Exceptional Sensor Readings A Guide to Normal Parameters

about 1.8g/sec per liter. This is sort of my personal rule of thumb and what I do, no guarantees with this. I use a value of about 1.7g/sec to ... the traditional B1 S2 sensor. The rear sensor, S2, reports voltage in the manner you described. The front sensor, S1, can report in several ... 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, ... Anyway, the downstream O2 should be somewhere in the middle (0.45V) if the cat is still there. The AF sensor though, as per the FSM, fluctuates ... As a forme ASE certified automotive technician, this is the best simple explanation I have seen in a very long time. Map sensor scanner reading · 3.9 psia or lower. · 2.4 psia. · 6.8 psia · 4.9 psia · 3.9 to 4.4 psia. If you measure the original MAF's IAT sensor with the meter set on the 200K setting should read around 45K at 60F. As the temperature rises, the ... I also checked the reading of MAF sensor, it is 2 g/s at ide, and 6-7 at 2000 rpm. I am not sure if these values are normal or not. If the upstream O2 sensor voltages appear normal (cycling) and the downstream voltage is tracking the upstream O2 voltage then your cat is bad. 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 ...
