Well, I bought the car back in November, I've done 250 miles since then :/ spent my project money on holidays and beer and now I'm left with a supercharged wreck that needs to be ready for summer!
I've decided to start driving the car, as even in its unfinished state it's a shame to see it sitting there. I must admit I'm not sure what demons are hiding in the car. It has a fairly unknown past, mod list and a DIY vortech install.
So it threw 3 fault codes.
0139 - Unknown Error
P1146 Heater Oxygen Sensor(H025) 2, bank 1 - Minimum Voltage Monitoring
P1147
First it seems like an O2 sensor, but I'm sure a number of modifications could of caused this error. And after some research seems that it could be 100 things.
Car seems to run fine, AFR seems ok to me, but I don't really know what it should be anyway!
What's the first step to fixing this?
Sorry for the long read!
