Which plug on the EZL is the rear crankshaft sensor - you referred to it earlier as the L5...?

I think I found it - it's the only one with one plug in it. Ohms checked out at 900 ohms...so I'm not sure now.....

Ryan, the ECU (or EZL) is mounted on the left (driver's side) inner fender. A new one costs around $2,500 so be sure to maintain your ignition system (spark plugs, distributor cap, distributor rotor & ignition wires) to prevent failure of the ECU. I went through that experience with our daughter's 1991 300CE.

Yea, I know about the EZL issues. I have just recently replaced the cap, wires, plugs, rotor, and coil...

To elaborate on the previous poster, the car shouldn't throw the cps code if scanned with the engine running.
