Getting codes p0340,p1700 and p1781
« on: 27 December 2011, 07:04:35 »

Hello..every one
I'm facing a problem with my omega 2.2 /2002 which started a couple of weeks ago .
first the EML light(car with spanner) went on and transmission went in to limp mode ...hard to change gears.
when scanned with OBD-II scanner I got p0340,p1700 and p1781 codes. I checked the wires,cables and haness connections but seems ok,so I replaced the CAM sensor with brand new VX genuine one ,cleared both engine and transmission codes and i'm still getting the same error codes and EML light still on and engine hesitate when reaching 4500 rev. appreciate your help ..Thank you

Still seeing cam sensor fault. Faulty sensor? Is it worth tracing the wiring back the ecu for faults/damage?

Ignore other codes until 0340 is resolved.

Are you getting that code from Engine or TCM?

CAN Receives errors are invariably caused by other stored codes in the Engine, TCM or ABS.  Clear all codes in these 3, and see what comes back
