Alternator replaced, now fault codes
Hey guys, I just finished replacing my alternator on my 01 S600. Everything on the car was running fine before I replaced the alternator. I followed the excellent instructions on this site for replacing the alternator. They were as follows...
1. disconnect battery.
2. remove passenger
side intake tube.
2.5 disconnect automatic transmission line to cooler (into radiator).
3. Remove radiator fan.
4. drain radiator from pet-****.
5. remove overflow tank.
6. remove windshield washer tank.
7. disconnect wire harness from passenger coil-pack, secondary air pump, and ground wire attached just underneath coil-pack.
8. remove secondary air pump and bracket.
9. remove idler pulley. (the one that's in the way)
This should give you enough space to harvest the alternator/generator.
After doing all this and putting everything back together, my check engine light came on, reading codes p0173, p0170, and p0378. Any thoughts on what I may have done to cause the codes. I did reset the codes a couple of times to make sure the were consistent.
