OBD II ?'s

[jerryg79]

So the other day my truck dies while im going down the road. Battery is dead. So easy enough I change the battery and the alternator just to be safe (alternator under warranty, battery so dead it wouldnt charge)

Well the battery was out of the car for a day, so I'm thinking that the computer reset itself. It was a bitch to start after I put the new battery in, but it finally started. It ran ****ty for a couple of minutes, but then it was fine. It ran like a motor with the timing ****ed up on it.

I started it 10 times yesterday throughout the day, and it turned over, but it still took a while to start.

I drove it to work today, and it died again, but it still turned over ok, just no gas getting there im thinking.

So here is my thoughts. The service engine soon light is on, read the code, it says "cam shaft to crankshaft misalignment error" this tells me that either the camshaft positioning sensor or the crankshaft positioning sensor is bad. But I dont know which and they are relatively expensive.

I'm thinking that since the computer has reset, it is freaking out because it is trying to get readings from those sensors and since one is ****ed up, it cant get the timing right.

Any ideas? Does this make sense or should i stop using this marker in a non-ventilated area?

Update....

I just went out to start it and it started fine.

The other thing i noticed is that the truck is running hot (again).

But it has cooled down now

So maybe the high temp is also ****ing up the computer relearning or what ever you want to call it?

Wow, someone should really do some maintenance on this truck!!!!

On a side note, this marker really does smell good!!!!!

What kind of vehicle. CPSs go out pretty often in powerstrokes. Maybe you should have a more descriptive signature. I have no idea who you are.

[jerryg79]

better????

I'm sure that doesnt help because you will still have no idea who i am.

anyway i was just going to edit to say that it is a '98 chevrolet 1/2 ton with a 350.

holy **** jerry i almost just pissed myself....

I don't know jack about the new chevy engines, but on the blazer there is a temp sensor ($13) that controls a bunch of ****...they are known to go bad and make the engine run like ****....Also the O2 sensor.... but it's weird your getting that camshaft ****

[jerryg79]

Damn it Doug, I thought you would know.

What about the all-knowing Fred or Flem???? any input?

[Doug Krebs]

yeah if that error is real.....your engine might be ****ed....misallignment between the cam and the crank??? Doesn't sound good to me....

[jerryg79]

I used Tom over at Offroad Unlimited's Scanner to run the code. He had the same problem with a 98 Z-71 he had, but due to the fact that he is quite possibly the biggest stoner in the world he told me in a voice similar to that of Tommy Chong "that he couldnt remember if he replaced the crank or the camshaft sensor"


I should have replaced both of them then (3 months), but I was broke as a joke and had to spend the money on the broke ass power steering instead.

PS I was mistaken it is a correlation error not misalignment, wrong use of the words.

nice sig fag, fred will be on here in a few, probably take a stab at it then. u r gay, try white-out it smells frikking awesome...

[uglyota]

Maybe your tchain jumped a tooth (or maybe distributor gear or dist. drive gear f-ed up). Will run like chit (if at all), hot, start hard, check engine light, etc. Doesn't explain the original alternator problem...I'd say take it to a shop with a reputation for knowing electronics. A messed up relay can act like a billion different mechanical problems.

smart ass

Well, If I remember correctly, the Crankshaft and Camshaft positition sensors do the same thing. I think it's a redundant system to keep things running. Did you change the cap and rotor or move the distributor? Check the actual sensors and see if they are loose or the connectors on them have any corrosion or are loose. How many miles are on the truck?

[Fredo]

hey, you gonna respond or what man? I'm trying to help.

[BMFScout]

yeah, it's like you are employed or something...

[jerryg79]

Sorry,

I havent changed the distributor or anything. only battery and alternator.

the truck has around 85000 miles.

I will have to check the sensors when i get off work
