code 41 1992 park avenue

Ok, makes alot more sense now. I understand better the functions on these sensors. I can test better with that info and hopefully pinpoint the problem. Will HOPEFULLY post back with cause.

When I replaced the cam sensor I noticed a groove worn into it, looks like this shape --> ( <--. About 16/32 deep. Is this normal wear?

[HotZ28]

No!!! Nothing should touch the sensor! It sounds like the cam magnet is trying to dislodge itself from the cam gear, if it has not already. Pull the sensor out and inspect the magnet ASAP. You may need to turn the engine and use a mirror to see it after you remove the sensor. Here is a good link on the subject;
Cam magnet replacement

[Cntrysthbst]

If I drop some small pieces of the magnet down the inside do I need to worry? Do I have to remove the timing cover to get those pieces out?

[HotZ28]

How many miles do you have on the PA? The reason I ask is, it might be wise to replace the timing set while you are at it!

[Loekee75]

Cntrysthbst, my timing set went out at roughly 140k, are you anywhere near that mileage? And, yes, the timing cover must be removed to gain access to the magnet, as it is (or should be) connected to the cam sprocket

[Cntrysthbst]

Good you are both bring up the timing cause I got a question bout it .

I went with HotZ28's post with JB weld for the magnet and sanding it down. Worked beautiful. My magnet was destroyed. Eight buks and two hours later I have no code. I would have started replacing fuel injectors/fuel pump if I wouldn't have had some GREAT advice. Thanks!!!!!!

I was turning my crankshaft to find the magnet in the cam sprocket, I went alittle to far so I turned the crank the other way to center the magnet. I noticed that the cam sprocket wasn't moving when I turned the crank the other way, with alittle more turning it started moving. Just seemed like alot of play to me. Engine runs fine, seems like I should have more pick-up when taking off though. Mileage is 130, 128. Should I replace the timing chain? Would this help the engine run better?

[HotZ28]

What you saw, was slack in the chain, when the cam gear did not turn with the crank gear! Again, I hate to be the one to say it, but you need to add the timing set to your list of things done to your PA!! Be sure to replace the tensioner also. With all that slack, your timing is retarded and that will rob power! You will be surprised how much better it will run with a new timing set! By the way, please state your mileage again.
Good luck

If it's anything like how mine turned out after a new timing set, you'll get MUCH better gas mileage as well...something that is good these days!

[Cntrysthbst]

I was afraid of that. It has 130128.6 miles on it. Just over a hundred and thirty thousand miles. Yes it does have lack of power when taking off, and when downshifting to pass. And the gas mileage is terrible, I mean it's bad!!!

The tensioner helps keep the chain from having slack in it right? Is that what your talking about replacing? Is there ANYTHING at all I should replace when I replace the chain? Like the oil pump stuff? The crank seal? Do I need to worry about the wear of the sprockets?

That JB Weld is still holding the cam magnet and is a great quick fix! I trust JB Weld but am worried about how long it will hold the magnet in the sprocket. The engine goes from cold to hot and comes in contact with oil all the time. When I replace the chain is it better to just buy another magnet and replace it the right way? or is the JB Weld fine?

Thank you both for all your continued help!

[Loekee75]

If I remember correctly, the timing set came with 1)-new chain (obviously!)2)-new magnet 3) new sprockets...they all need to be replaced at the same time..(kill 3 birds with 1 stone, right?)
An oil change is done at the same time, and they had my cam sensor replaced while they were down there. They also remove the water pump, so that's your call if you want it replaced as well. Correct me if I'm wrong, but I believe Hotz28 was refering to the serpentine belt tensioner?

[Cntrysthbst]

Ok, sounds good. Ya your right about the tensioner I was focused on the inside of the timing cover - was thinking of the damper. Thanks

[Cntrysthbst]

HotZ28,

Just a quick question. Started thinking to myself why the drivebelt tensioner?So just to double check - I've always referred to the chain damper as the tensioner for the chain. To me there are two definitions for the word tensioner on my car, one for the chain and one for the belt. Am I to replace the belt tensioner or the timing chain tensioner? Just wanted to make sure which one you are talking about! If you are talking about the chain tensioner, how would I know if mine has a chamfered of counterboard hole? Thanks

[HotZ28]

The parts below are what I used. I also put a new magnet in the cam gear (dealer item) and replaced the water pump while it was off. (Cheap insurance) If you will notice, there are two cam chain dampers (tensioner), one with chamfered bolt hole in block and the other with counterbored bolt hole in block. Wait until you see what you have prior to purchasing that item. The gasket kit should include everything you need for the front cover and water pump. The parts are available at most parts stores. Be sure to change the oil after the work because you will have coolant in the oil!!

Thanks! Code 41 now is like getting a transmission code. It's not a good one to get. Might run into a question through the process, if not will let you know the outcome!
