So my check engine light has been on for a while now. I checked it when it first came on and found it was my exhaust manifold pressure sensor. I found out the pressure tube was plugged up with soot (common problem for my engine), but didn't have the 27mm deep well socket to take out the sensor and fix it until today.
So anyway, I took out the sensor, cleaned out the tube and then hooked up my diagnostic reader to delete the trouble code. When I did that I found out that I had 2 trouble codes, the original one for the pressure sensor and this one:
P0461 Fuel Level Sensor 1 Performance / Rationality
I watch my fuel gauge like a hawk and I know for certain that it's working just fine. While I'm not certain, the only thing I can figure is that the ECM just can't figure out how the truck could possibly go that many miles without the fuel level moving very much.
I think I should be proud of myself
