OPDA not lining up

[lulzpwndyah]

Hello it's been a while but i'm back after attempting to replace my own OPDA. I got a P0016 code and Jeep went into limp mode while driving. I got under the Jeep and rotated the crank by pushing up on my ratchet so if you're looking straight at the Jeep from the front I turned Clockwise. Once I saw the holes in the OPDA lineup I took out the pin from the new one and stuck into the bottom of the old one and pulled the thing out. I then took the pin out of the old one and put it back into the new one I tried sticking it back in and it's not seating properly in the same orientation as the old one. It will seat flush if I turn it almost 30/50 degrees, the old one won't go back in either now in the same orientation. I need help please, not really sure how to proceed from here. I'd prefer as easiest as possible and doing solo and i'm not that strong due to disability so I struggled a lot turning the crank.

hoping I can get this fixed tonight because I need it for work.

Maybe a dumb question but is it rotating as it goes in, following the cut of the gear? It's been a while since I swapped one out but if I recall you start it in clocked out of position and it'll rotate as it drops into place. If that makes sense.

 

[lulzpwndyah]

Yes it is turning as I drop it in and that's how it ends up out of orientation, if I take a look inside of the hole I can see the horizontal slot for the tip of the opda is in the wrong orientation as well.

 

[bluescapegoat]

but you can't just start it further out of rotation so it drops in the correct positioning? You can reach in there and rotate the oil pump with a screwdriver if needed.

 

[lulzpwndyah]

no, to do so I would need to turn the pump so far towards the engine that there would be no room for it to turn that way. I can reach in where? I can add pictures if need be.

Maybe somebody else will chime in but if everything is in the same orientation and you're using the pin I would think if it's off a tooth (or several) it would still be reading the right timing. But I don't want to lead you down the wrong path.

The slot in the bottom when you look in with the OPDA removed is the oil pump. It can be rotated to line up with the drive on the bottom of the OPDA

If it's off a bit the Jeep either won't start or will start and throw a code and not rev past 2750ish rpm.

Swap out to use your old Mopar sensor, if that's an option. Can save a bit of headache.

I used the Crown OPDA on my 06 Golden Eagle. Was first time I attempted anything like it. Had to use screw driver to get orientation On the oil pump correct. I swapped out sensor for original Mopar. Started right up and no issues . Inspected gear on old drive and luckily was not worn or making any noise. Piece of mind for $120 purchase imo

You have to turn the oil pump slot to about 11 o'clock with a long screwdriver to get it to go back in to the same point it was in when you took it out.

However on your 05, it doesn't matter where the OPDA winds up as long as the wheel is pinned to the housing when you put it in.

do you have a source for this? If I turn it on and it's not lined up will I cause any damage?

 

[JKP]

There are multiple writeups on the 05, 06 OPDA installation out there.

The only thing that matters is the tone wheel is pinned to line up with the cam sensor at TDC on Cyl 1. If it's not lined up you will get a crank/cam sensor mismatch error code and the PCM will go into limp mode.

The engine and PCM don't know or care which way the OPDA housing is pointing as long as the wiring reaches.

I just went out to my 06 LJ and snapped this picture of what my ODPA looks like with regard to rotation so you can use it as guide.

I think when you put your ODPA in and you were able to get it clocked and screwed in then you did it correctly. The P0016 code is due to you installing a new Cam/Crank sensor that is integrated into the ODPA. To clear that code you need a bi-directional scanner that has the Cam/Crank Relearn feature to tell your computer how to adjust the timing for the new sensor. I also installed a new computer from WranglerFix around the same time and maybe in my case thats why i needed to relearn. But it says in the description for P0016: The correlation of the camshaft and crankshaft positions on bank 1 is incorrect based on the intake camshaft position sensor. The "correlation" is the computer thinking the jeep isn't timed correctly. I doubt its a mechanical issue with how your ODPA is clocked. I think its a computer relearn issue.

YMMV

Do all the new OPDAs come with an alignment tool?
MIne's been on the shelf for several years and does not have one.

 

[lulzpwndyah]

This is how it was before I removed the original

 

[lulzpwndyah]

This is the new one.

The ones from Crown Automotive do. They are pinned through the bottom hold with a black plastic piece.

When i installed my Crown OPDA it wasn't clocked identical to the old one. The way i looked at it, as long as you had the black pin in the right position (which it looks like you do ) and the new one slid right into position, albeit at a different final resting position then i'd say its correct. I still think you need to cam/crank relearn procedure done.

You’re fine. I posted a thread with the exact same issue in June, then found the answer on here before I got a response. I moved forward without any issues.

He's not fine. His jeep is throwing a P0016 code and is limp mode.

I had not driven with the new one in place yet. I followed the advice tightened it down and closed everything up went for a quick 5 minute test drive and no code and it drove fine. I guess tomorrow will be the true test on my way to work lol
