My friend bought a 2000 Eldo with 169k on it. He bought it with the Service Engine Soon light even though I told him not to do it. The car is actually really clean and runs good for the most part but I checked the codes to see what the cause of the engine light is and its throwing a ton of codes. My hope is that they were caused by the motor being washed down which from what I understand the guy he bought it from said it could be from and that it will clear itself eventually otherwise I suspect my friend is in for a nice expense. We cannot inspect the car until this is recitified and he is on a 20 day temp. I'm hoping someone here could shed some light on this issue. Below are the codes which I already deciphered.

Thanks in advance,
Adam

These are most likely the result of a ripped plenum. It has been discussed many, many times. It may even be resposible for the MAF code. Do a search for it. Especially an advanced search for posts by Submariner409.

As for the rest. It's hard to say if they where caused by a wash or not. Clear them and see what returns.

..............and, for your friends' OBD-II system, it makes a difference whether the codes are Current or History.

Ooops sorry. Yes they were all History codes. I cleared all the codes to see what would happen. The light did go off but within a few minutes after driving the light was back on. I rechecked the codes and so far only one code has reappeared. It was the P0340 code and it now says Current rather then History.

P0340 - Camshaft Position (CMP) Sensor Circuit
P0385 - Crankshaft Position (CKP) Sensor B Circuit
CKP sensor failures are common on 2000- early '03's. Gm had a bad supplier. Replace them both.

what can he reasonably expect to pay to have both sensors changed out if he took it to the dealer or a mechanic?

I really don't know. I think I recall hearing CKP sensors where $400 - $500 at the dealer. Not sure about the CMP sensor. It is a little easier to access so it may be less.

The sensors list for around $55 -$70 apiece. The labor is around 2.5 hours total. At $90/hr and $180 for just sensors, you're looking at $400 +.

If you're of a DIY bent, look at www.rockauto.com, surf to your car, and look for the 3 sensors, price-wise. Search the Forums for the location diagrams - they're posted in here and Northstar Performance multiple times. In your garage, with a jack and stands, 3 hours, bruised knuckles, and half price.

(damn, you're quick..........................!!!)

Yes, from beneath. Tight quarters, but doable. You'll need to remove the oil filter adapter. They are above it. Sub has posted some good diagrams.

Sounds like he is in for some expenses to get the car on the road and has 19 days to do it before his temp expires. Also now gotta see what other codes resurface as current in the next few days.
