Hi. I have a ford 1.0 ecoboost. Came with a p0172 system too rich bank1 and p2196 oxygen sensor signal biased/stuck rich bank 1 sensor 1.
I tested the evap purge valve and going through the duty cycles it would stop clicking. So I changed the purge valve and now it works through the range and stops at 100%.
The stft is at -29 and ltft is 0. And fuel status would go to open loop fault and stft is 0 then and if I give it a rev it would go to closed loop and stft back to -29.
I swopped the injectors out with another set I have in a old head from a motor with piston failure to see if anything changes and nothing. Keeps running rich. Cleaned the maf as best as possible as it is like semi sealed.
I will see what the o2 sensors are reading, but not sure if all the pid is there for both sensors. As the bank 1 sensor 2 data I found under a different place as the normal live data. Think it's like 06 data under service section on the autel scanner. I will check it all in the morning when I am back at work. Thanks
Yes. I reset the pcm learned values. Oxygen sensor 1 only shows heater duty cycle and it is at 43% on idle and when I rev it goes to about 50 and on deceleration drops to 35.
Oxygen sensor 2 shows voltage and reads 0.89 on idle and as I rev it drops as low as 0.7
Fuel rail pressure reads 3 Mpa on idle and goes up to about 15 Mpa as I rev it up. Fuel rail pressure sensor voltage is 1.11v at idle and goes up to 3.43 when I rev it up
Another thing I found is that in the freeze frame data it shows ect2 -40 celcius. But I cant find a 2nd act sensor. I only see the 1. Could it be that it is just there for the scantool incase it has another ect sensor.
