Hi All,

I pulled the code 2 from pin 7 and code 8 from pin 4 from the X11/4 connector using K6JRF's Page as a reference; however, I'm not sure if they're applicable to a 1994 C280.

[Fault Table, DTC Readout, LH-SFI Module (N3/1)]
DTC#8 - "CMP sensor (L5/1), open/short circuit"


Fault Table, DTC Readout, EA/CC/ISC Module (N4/1)
DTC#2 - "EA/CC/ISC control module (N4/1)"

The codes were pulled due to an OBDII "P0505: Idle System Malfunction" resulting from a Check Engine light.

Can someone please help in troubleshooting the above codes and what the possible causes are. I'm at a loss as this is the first time I'm working on this car.

Thanks to all,
