I happen to pull the following Peake reader codes:

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o></o>
1b – Table 18<o></o>
Cd – Misfire during warm up, Cyl# 1<o></o>
0A – Exhaust camshaft position sensor, Cyl# 1-4<o></o>
0F – Crankshaft/Camshaft position correlation Cyl# 1-4<o></o>
<o></o>

My assumption is that 0F (Crankshaft/Camshaft position correlation) issue is responsible for all of them. Not sure why this would happen since 20K miles ago (Last Summer) the Timing Guides/Rails along with everything else in that area was replaced and engine re-timed using the special tools. All bolts torqued per spec as well. <o></o>
<o></o>

Anyone had this combination of codes yet?<o></o>

cam crank correlation usually means timing is out, since you have a cps code i would test/replace the cps first.

I hope it's as simple as a CPS sensor. It would suck going back and retime everything since everything is so nice, tight without any leakage.

I do remember replacing one of them on that side of the engine prior to working on the timing chain guides/rails overhaul. Can’t remember whether or not it was the Intake or the Exhaust CPS. Will try to find the receipt to verify which one was replaced.<o></o>

Thanks for your input!<o></o>

Someone else asked about this yesterday and I have been trying to find the trigger that sets the code. The best I have found so far is that when the DME checks cam position and can't determine position in relation to the crank position it sets that code. I believe that is telling you that the computer is not getting understandable signals from more than one CPS.

The CPS code is set when a voltage of <.5 v or> 1.5 v (could be 2.0 two manuals two different answers) is returned to the DME. The OF code will likely come when the info (read volts from .5 to1.5 or 2 ) is inconsistent. When I started having VANOs issues I had to replace all of the original CPS before I got the codes that were understandable. The original CPS are known to be not great or reliable. My advise would be to replace all of the original CPS as likely all of the old ones are sending signals to the DME that are less than accurate. You have replaced one, now a second is gone how good do you think the other two are?

That said you gave the description for code OF not OE, OE is a leak in the tank. Your other codes suggest OF

No idea in what condition the others are. Bought the car last Summer, donno much about it other than the stuff I did of course:sad1: Spent quite a bit to make it as good as it gets and now this thing. I'll start by replacing first the one. May end up replacing all of them:dunno:

BTW - thanks for bringing the 'OE' vs 'OF' to my attention. It was a typo which I just edited and fixed.

I suspect that you will be doing all four eventually. When I did my four I figured great, but with the new accurate sensors I got some vanos codes which meant I needed to clean and replace the solenoid o rings. Once I did that I was golden.

Forgot to mention 'the VANOS'. Yes, I rebuilt those at the same time I worked on the engine. I however chose OEM O-Rings instead of the aftermarket 'improved' once. So, after I think about preventative maintenance done, the chances are high for CPS sensors to start giving up on me. After all, the Beast has 150K on the odometer.

Tons of work I did over just a year of timeframe. Not to mention the suspension, driveshaft and of course the mods, tons of tasty mods.<o></o>
Well, I'm not complaining at all. It is rewarding once you find yourself behind the steering wheel of this magnificent time machine. <o></o>

Considering the CPS and frequency for failing I'll go ahead and replace the rest of them as well.

BTW - I just got my Powerchip tune in the email. Can't wait to get home and flash the Beast!

 

[Sailor24]

Sounds like we are in the same boat. I have 175kms and it was not up to standards on maintenance. The work is worth it.
OEM o rings for the VANOS are the only way to go. Techs have reported problems with the others.

Your problem is the exhaust CPS.

The cam error is as it says only a co-relation error doe to faulty cps reading.

Everything normal,change the CPS and the errors disappear.

 

[nanda007]

Kinda confused now! I chose to clear the codes prior to flashing the ECU with Powerchip tune. It has been almost 2 full days me driving like a mad man around without any codes. The engine must have benefited from the tune. I know the tune does mess with the timing which most likely brought it back within the tolerances.

Well, so far so good. BTW - the tune is highly recommended. I love it! It feels and moves faster! No more gaps in certain RPMs.

The computer needs some time to relearn. I thought I had something fixed once but about ten days later it came back and then back again and again just like it did before I put new parts on. That was the exhaust cps's. The new program may very well change the behavior of the vanos.

I agree. All I can do is wait for now. Might as well go ahead and have my inspection done while no codes present. It is due next month anyway. Gotta check my rediness state with generic OBDII scanner. was too lazy to check it out last night. As the metter of fact, will check it after I get out of work, the scanner is in the trunk.
