V6 TPS and Limp help

[Burty92]

Hi Guys,
This is my first post and am new to using forums.
Purchased my first project (2002 406 v6 coupe) and no doubt I will be flicking through this forum a lot as I would like to restore it as much as possible.
After using OBD tool I only have 2 fault codes so I am quite happy but I do have a few queries I would like help with.

the car will start and idle but wont rev.
the OBD shown a fault with the TPS so this is my first port of call.
Is the TPS the same on the 2lHDI as the v6? as I can only really find replacements for the 2lhdi.

The car is in need of a new clutch as it will only go into gear when not running and wont disengage fully when in gear and running, I tested the master cylinder and this seems ok so I presume the clutch has gone. could this also cause it to not rev above 1-2k? (limp mode?)

Thanks,
Burty92.

Hi and welcome :-)

The OEM part number for my 2003 model year 2.0 HDI 110 is 1920X1 (see number 19 here)

Which is the same as for the 2002 V6 Coupe (see number 21 here)

After-market parts can be found here: https://www.autodoc.co.uk/car-parts/oem/1920x1

I think the not-revving is most probably caused by the faulty TPS.

Seems indeed you stepped "through" your clutch. I've had the same issue, I had to push down the pedal really deep and even then the disengaging was very difficult. The clutch itself needed to be replaced.

You might also want to look around on that other forum, which is targeted at the Coupe variant: https://406coupeclub.org/PHPBB3/
