Hello,

I have code E 61-3 (with blinking spanner) on my Martin cab over 8FGU25. Nowhere inside the service manual does it specify this specific code (ends diagnostic code menu at E 62-3 and starts at E 63-1. Not very helpful. After some digging I found the code specifies "Pressure sensor open abnormally (P-port)." Now that I know what the code is for I looked all over the oil control unit and I cannot find that specific port. Need to verify if pressure is actually low or just sensor fault.

Thanks
