P0013 fault code Need help

[gpt817]

My 2002 996 Turbo CEL suddenly lit up last weekend. Then, I used my durametric and the fault code showed "P0013 Camshaft Adjustment bank1 Open Circuit". I could erase the fault but it comes back after driving a couple of miles. I didnt feel any changes on how the car runs even at .7bar boost. It drove normally.

Can anyone help me fix this problem?

Thank you.

Possible fault cause

- Open circuit in triggering wire

Thank you. Will work on that.

The solenoid in relation with your fault is item #23 on this picture. His function is to provide engine oil pressure to the cam actuator to retard or advance the cam (0 to 45 degrees). Here you have the two wires going to this solenoid and the color of the wires....

Thanks Jpflip. :thankyou: Appreciate it. Will work on the car this weekend.

Question- will I damage the engine if I continue driving it? If I can drive it, how hard can I push the car? No one follows the speed limit in our country. That's our valuable freedom here in our country- we can over speed anywhere and the cops wont pull you over. They dont have radar guns too. :)

In case I need to replace the soleniod, do you a part number for that? Thanks again.

There is a site that give you all the Porsche parts catalog it is AutoAtlanta and you will found the parts in question item#23 and #24 AutoAtlanta 2. #23: camshaft actuator 996 105 303 71 and #24: o-ring 999 707 504 40.

For your question about driving it that way, I cannot tell! Having a "real" fault on a variocam system is evident. If you got a Durametric you can reproduce what a fault of this system represent. You have to use "drive link" and select the bank you want to fail. You will see a very strong change in engine RPM and engine sound.... This is the only experience I got with a failed variocam system.

:thankyou: Thanks again. We first checked the connectors, tightened the clips a bit and sprayed contact cleaner. Then, we connected a 12v line to the soleniod and it clicks. However, when I used the "drive links" of the durametric, it couldnt activate the bank1 solenoid. I activated the bank 2 and it clicks. Afterwards, we checked the the b+ line, there's continuity. We still haven't checked the trigger wire going up to the DME. Will do it today.

Nevertheless, I test drove the car yesterday and it was normal. The CEL didn't lit up (it lights up after driving one miles or more) but when I used the durametric, the "P0013 camshaft adjustment bank1 open circuit" was still there. We will continue looking for source of the fault. We havent checked the harness and connectors on bank to leading to the DME.

Is there an easier way to check the trigger wire?

Best regards.

Nothing other than what is mention in the troubleshooting manual, sorry...

Hello again, Jpflip.

I drove last sunday my 2002 996 turbo and got a CEL after a few miles driving. When I got back home. I used the durametric and found these codes:

p0013- camshaft adjustment bank1 open circuit

p0300- porsche falut 507 misfire detection

p0301- porsche fault code 508 misfire cylinder 1

p0302- porsche fault code 510 misfire cylinder 2

p0303- porsche fault code 512 misfire cylinder 3

The CEL light was flashing before I plugged in the durametric.

Can you give some clues what these means and what to do? I erased the faults and its back to normal. the CEL comes out after taking a long drive.

Ive already check the trigger wire and the b+ and they had connectivity. I suspect the soleniod is faulty and is causing the p0013 code. I ordered one with the o-ring at autoatlanta as you reccomended.

Thank you.

You definitively got a problem with the left bank. But can, the variocam malfunction give you a misfire ???? The answer, according to the OBDII manual is yes. See pics... The pictures included are all related with a fault P0300. And when your reading the troubleshooting it become clear, you are having a real problem with cam timing. If the replacement of the solenoid doesn't fix it, it can be the cam actuator which is a bigger job, special tooling needed, and also a lot more expensive....Keep us inform of you findings....

Just found a previous discussion about the same problem. Iceyankee-tsi was able to take the solenoid from the right cylinders and switch it to the left to be able to found out if the solenoid was at fault. It is interesting to see the progression but we don't have the follow up and final fix....

Hello JP,

Yes, I read the thread of Iceyankee-tsi.

We removed the solenoid yesterday. We got a 11 ohms reading using a digital tester. When we put in a 12v to the solenoid, it wouldn't click right away.After a few jolts of 12v it clicked. After jolting it several times, the clicking got louder and louder. It seems it is faulty or maybe it needed a workout of 12v current. I already ordered a solenoid from autoatlanta.com. Hope it gets here in a few days.

We checked the wires b+ and the trigger wires and there's continuity. We plan to remove the solenoid of bank2 today and swap it on bank1. The engine compartment is so tight and we have to make a special 32mm socket wrench to remove the solenoid. Will keep you posted tonight or tomorrow morning.

Thanks for your help. Eventhough we are from different countries, We are brothers in Porsche. God bless you. :thumbup:

Hello JP,

We finally found the source of the "p0013 camshaft adjustment open circuit" fault code.

It's a simple wrong connector for the wrong socket. The connector going to the solenoid with grey/red and red/blue wires was plugged into the socket of the blow-off valve socket. While the connector for the blow-off valves socket was plugged in to the variocam solenoid.

A couple of weeks ago, I had an independent porsche mechanic fixed the water leak at the oil and water cooler at the back of the throttle body which required aluminum welding of the water plug. He removed a lot of parts to get into the oil/water cooler and apparently plugged in the wrong connectors to the variocam solenoid when he reassembled the car..

We removed the solenoid the other day and installed it back yesteday afternoon and plugged in the right connector- WALAAA- the P0013 fault disappeared using the durametrics and no more CEL. The car zooms faster now than when the fault was still around. Probably the DME retards the timing when there's a fault code.

Thank you very much for your time and concern in helping me out. It was only to find out a wrong connector was plugged in to a wrong socket.

Well, that's a lesson learned and I had fun. Best regards.
