This code can be caused by:

A loose connector at the sensor

Corrosion on the connector

Bad wiring from the sensor to the DME

Bad sensor

Bad DME

Paul sorry not clear on this. Is this how you shut off code or something you do after. If after please define purpose. Thanks is advance.

You need to read and clear the code(s) using a Durametric or PST2. They do not clear themselves.

Once cleared you need to do the 90 second procedure so that the DME can relearn the base value of the sensors.

Well I tried this and made it about 20 miles ...shut it down and thought i was home free. this was an improvement because I have tried a couple of other times and only made it a couple of miles. I started it up after a brief shut down and took off and the light kicked back on. Just checked it out and same code PO341. before this I changed the plugs and reversed the coils from left to right side. I am perplexed. Any other suggestions?

[Paul]

Please elaborate on "replacing the plugs" and "cleaning the connector."

What are you calling the coils?

Lietrally took out the Beru spark plugs and replaced with 4 electrode Bosch and remoed the coils which are connected to eack plug with two bolts to the head. Every plug has a coil?

The spark plugs and their coils have nothing to do with this code.

I think you need to take this car to a indie shop and just pay the 100 bucks diagnostic.. it sounds like you've spent more money fixing what isn't broken in an effort to save money. My hats off to you, but sometimes a good shop can save you money...

keep us posted, and good luck

P0341 is for an “implausible signal” from the cam sensor; what you should be looking at is the signal itself, and the route it takes to the DME.

First, using a digital multi-meter, with the ignition on, between the ground pin and pin #3 on the rear of the cam sensor plug, you should see 5 Volts. If you do not, the sensor is not getting power.

To check for continuity (test the wiring and connections to the DME), you will have to have a Porsche pin out box #9616, which is hard to come by. You can “jury rig” connections using some wire and plug, but you would need a wiring and pin layout diagram to accomplish this. If you do this, you should see 0-5 ohms on the power supply wiring, and infinity on the sensor to DME wire.

Tracking down these wiring issues is pain without the correct tools……….

If you do this, you should see 0-5 ohms on the power supply wiring, and infinity on the sensor to DME wire.

And infinity from each of above to ground with them disconnected at both ends.
