Hey Everyone,
I’ve gotten the P0172 code as I’ve seen many other have and been replacing part after part and testing my O2 sensors via a multi-meter. All seems to be one but I was looking at my freeze data today as it started acting up again and not sure what values are good or bad.
Can anyone give me a hand by chance? Trying to determine what pet is bad before I start replacing everything...
LAMDA11 = 0.960
O2S11 (mA) = -0.145
O2S12 (V) = 0.705
MAF (g/s) = 3.27
LGSO2FT1(%) = -0.8
LAMBDA = 0.999
If other values are needed I can pull them.
I’ve already replaced my MAF and Thermostat.
I was going to replace my upstream O2 but thought the reading looked fine so didn’t.
Also If I clear the code I am good with no issues for about 50 miles or so then it comes back and acts up.
Thanks in advance.
