Hey there,
2000 Gmc Sonoma 2.2 throwing code p0178 fuel composition sensor low frequency. Recently replaced both upper and lower O2 sensors. Not even sure if my truck is flex fuel. Checked gas cap, vin # fifth digit is not a 5. But I can see what I think is the sensor under wheel well near right front tire. I've seen those replicators for sale and wanted to find out if anyone knows anything about them. Or should I try to replace it from junk yard? Help? Thanks for reading!
