Hey Guys,

94 C220 has thrown a code P1341. The only issue I am having with it is rough idle when stopped, idling around 500rpm. I just replaced the MAS sensor, but that did not help. I put a new OVP relay in it, that did not help.

Anyone have an idea. Help would be greatly appreciated.

Thanks

Jason

P1 341 means that when the variable intake camshaft timing gear moves it should make a change in vacuum of the engine.

Possibly the intake camshaft isn't returning at idle to the fully retarded position.

Hi MBDoc,

Thanks a ton for the reply. How do you go about fixing that? Do you think the sensor is just bad?

Thanks again

Jason

When the code is erased does it come back immediately?
IF not you won't be able to find the cause!

Not sure,

How do I erase the code? I took it to a local advance to have them read it. Could the plug wires and plugs cause it to idle rough when stopped and the idling drop to about 500? Also you don't think that is the Cam position sensor?

Thanks

bump, anyone on the above please

Jason

Don't assume that the rough idle and P1341 code are related. You could have two separate issues.

The majority of P1341 codes are caused by malfunctioning camshaft advance mechanism's, IMHO. Since they're actuated by by oil pressure, they tend to get "gunked up", especially on higher mileage cars. Of course, there are other things that need to be checked before you replace the timing device, which isn't exactly a DIY job.

Make sure that the camshaft solenoid is connected properly. It's the big round thing on the front of the engine, drivers' side. It only has two wires going to it, but look at them carefully. I've heard that some mid-nineties MB's have had wiring harness issues.

Thank ILUV,

I will clear the code and see if it comes back, if it does I will replace that sensor
