Precision at Your Fingertips Master Normal Sensor Readings

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. I think rule of thumb is 1 g/s per liter of engine displacement so we should see something in the ballpark of 3.5g/s in a normal engine with no ... 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 ... O2 Sensor Readings ... P0420 appeared this summer. Fixed leaking flex pipe, but code comes back with every highway drive. 3.2L with 100K. Gas ... With the engine at normal temp (80-100C) and airbox in place, VERY rough readings should be: Idle rpm = 20 kg/hr 1000rpm = 30kg MAF signal voltage range is 0V - 5V. The higher the air mass the higher the voltage. So it definitely won't be 5V at idle. It will be somewhere above 4V at ... The computer recognizes the sensor as hot and active once there are several cross counts. You are looking for voltage to go above and below 0.45 ... 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)?. As a forme ASE certified automotive technician, this is the best simple explanation I have seen in a very long time. It will read very rich almost all the time in around the 0.845v range give or take a little but then if you just let it sit it will drop down to 0.1v or below ...
