Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Cam Shaft Sensor P0340 error ECU on 3.7 Roadster

I wanted to make all you V6 roadster owners aware of an ECU error I recently had. The car reported a P0340 error which is cam shaft position sensor. On tracing the error I found that the wiring loom at the back of the engine (n/s) - which is not easily visible, was partially severed by the corner of the air filter box rubbing on it. I had to repair the loom, which I then re-routed. So my fellow V6 owners, please check this on. yours. It is only really noticeable once the air box its out. Mine is a 2016 and here is the link to the thread

Taken the liberty of copying across from PM conversation Dave and I have had regarding his 3.7 Roadster.

Sorted!! You won't believe it - the bottom corner of the air intake box is incredibly close to the back of the engine and it had rubbed through the wiring loom that connects to both cam sensors (plus a few others). it's just pathetic build/design . Anyway I had to strip the whole loom back , cut the breaks out and solder the broken wires, then re-wrap the cables. This is the 3rd loom failure the car has had!! I filed the edge of the air intake away and re routed the loom. I then had a look around the rest of the engine bay and there are lots of accidents waiting to happen!!

This pic of mine without air box illustrates cabling in front of heater hoses.

Thanks Richard! Also, I noted that the plastic top of the sensor where it protrudes from the block can rub against the front face of the air filter cover. I'm going to make a cut out in the cover (which will be on the intake side of the filter rather than the engine side)

I also noticed on mine that the water expansion takes wears o. The wiring at the front of the engine
