Hi Guys, please help me save my car!

2000 hdi90 rhy engine 230k miles

Intermittent P0220 and p0120 throttle position sensor codes and associated limp mode.
I have changed the tps with a second hand unit from a known good source, no change.
I have checked the 4 wires for continuity from the tps to the ecu, while flexing the cable loom in various places, all good.

Being an electronics engineer I doubt the issue lies with the ecu, so I am reluctant to throw money at that.

I believe an ecu change involves more than just that?

The car is a bit tatty but I've had it 8 years and maintained it well, but I guess if fixed it's still only worth a few hundred quid.

Any ideas would be very gratefully received

Tony

Thanks for the reply,

Well it came off a scrapped car with a broken cam belt, I was told it was good. so, no I am not 100% sure, but pretty sure.

Fixed (I hope)

Found a path to ground on one of the wires from tps to ecu. Replaced wire and it now seems fine. fingers crossed.
