Hello all,
After an engine swap (dead 4.0 to 4.6) ive got a P0340 code and subsequent struggling under load.
I used my old sensor so im pretty sure it will be a wiring issue.
But where does it come from the ECU so i can test it?

many thanks!

Hi, if only the camshaft sensor input to the ECU is what you want it goes to C0636 -pin 20, see connector views https://www.dropbox.com/sh/47hbz40an5he5j2/AAC8m5eHoojsOSxikJGWeXrHa/Electrical libary 03MY.pdf?dl=0

Some say a 4.6 will run on the 4.0 map in the ECU. some don't. Could be why its struggling under load.

Don't know what that code is without looking, is it a knock code or fueling?

code is camshaft position sensor. the 4.6 should run on the 4.0 map, not the most efficiently but it should be able to compensate. with a 4.6 maf and remap it will though - will be interesting to see the difference when i get this done.
