I have a 1998 SLK with 120k, the cel came on, I scanned it, the code was p1519 so I changed the cam solenoid and still have the same code after it was cel was cleared.

I checked the solenoid. It shows 8 ohms
The power to the solenoid read 7volts.


The MAS has been cleaned.

I've checked the vacuum lines and found a few dry rotted rubber connectors and have replaced them.

I don't want to just throw parts at it. Anyone have any ideas what to check next?

Thanks for your help.

Sounds like a fault in the K40 if you only have 7 volts

Here is the MB test steps

The solenoid is powered from the K40, fuse 2 under the ECU cover. The red and green should have 12+ volts with the key on or running. The gray and brown is the control side where the ecu (me-sfi) provides the ground and turns the magnet on

Thanks for the info.

I have pulled the k40 out a few years back and re soldered the 3 problem connections. after this repair I didn't have the code

I didn't see any oil on the wires but pulled the insulation back and soldered in a joint to act as the oil wick stop.

I guess my next question would what to look for next?

1)Is the magnet that is bolted to the cam fixed tight in place and move with the cam or does it spin free? It spins free currently. I ask because my thinking is that if fixed tight it would show the movement of the cam.

2) How do I test the gray/brown wire control side is working? What reading reading should I be looking for?

3) Do I test the gray/brown wire on both ends and make sure there is not a break there?

4) Any suggestions?

I know the background maintenance on the car as it was purchased new by my father. When he owned it is sat in the garage for 4 months at a time.


Thanks for all your help.
