CODES 51 and 52 (hmmm must be a common problem)

[SUPRASTEVE]

Well Here it is I checked my codes and i got 51 and 52
But something else puzzles me....
I found another hose on the floor it is about 5 in in length and it has a clip on it like if it where connected to another hose it is a long clip with a rounded place on the other end to fit maybe another hose
It looks like the hose just came apart due to being old
Bad thing is I don't know where it goes I am thinking under the car but where to look....
Any ideas and as for the codes which one is priority and how do I fix it?

Oh yeah and about that hose it came off from where the starter is located mayube that'll help beacause i can't find it! =( :1zhelp:

51 and 52 common? Dunno, never had either myself.

Is this a vacuum line? If so it may be part of the vacuum routing for the ACIS. Most of that system is tucked under the intake manifold. If your vacuum lines are bad enough to just fall off, it's time to replace them.

No they don't come off by themselves it was when we were changing the starter
we had to lay on the engine and we pulled some hoses off in the process :3d_frown:
