    Default What part is this? 1988 205 gti

    Hi All

    Advertisement


    I'm in the midst of replacing the clutch on my newly purchased 1988 205 gti. While removing the gearbox I unbolted the part in the picture from the rear RHS of the engine, just next to where it mounts to the gearbox (approximately underneath the distributor). The wire attached to it was broken a little way back so I can't see what it's meant to attach to. It looks like it might possibly be a crank angle sensor but it wasn't attached the way they normally are and the engine runs so that seems unlikely. Does anyone know what this is and how it's meant to be wired in to the loom?

    Could it be a pickup for aftermarket cruise control?

    No aftermarket cruise control that I can see fitted.

    Yep, it's the crank angle sensor. But shouldn't exist on a 1988 GTI. In actual fact it looks like the Si bit I pulled from my parts car. You probably got an Si g'box someone couldn't be arsed removing the TDC sensor from. Pretty half arsed if you ask me. I would get worried seeing such sloppiness.

    Looks like a crank angle sensor alright. Crank angle sensors were fitted to a lot of cars that didn't seem to need them (and had their brown connector plug hanging from the clip under the cam cover bolt on most 8v XU engines). I believe they were used for a CitroŽn diagnostic/timing device. OK to chuck in the bin.

    Or keep in case you want to upgrade your ignition later.

    Funny, my '88 had one of those, too.

    It is and it isn't a crank angle sensor. Jetronic cars had a sensor purely for diagnostic capabilities. It would have only given RPM. Most likely a Peugeot mechanic forgot to remove it. It wasn't fitted as standard.

    Thanks everyone for the response! Since it's not needed, I think I will chuck it. It looks pretty cactus.

    Good point - a speed sensor rather than angle sensor. It was standard on most carbureted BXs in NZ. Especially series 1.
