Any tips for removing the corrosion as it has to be soldered rather

Hack it off if there's enough slack.

Sadly, there's not. And experience with this sort of corrosion says it
usually goes quite a way in. But after cleaning the end and making the
correction the circuit shows a decent low resistance on my ESR meter. But
most of the sensors have a fairly high resistance anyway - so a few ohms
probably wouldn't matter unless it got worse. The injector drive circuits
are fine - and they do need to be low impedance.

I've had success with just
scraping before - but I suspect it's nowhere near as mechanically
strong as a 'proper' joint, even if it ends up electrically OK, and
might just be asking for trouble 20 years down the line.

I'll be dead by then. ;-)

Rub them between two pieces of very fine emery paper.

I usually just scrape with the edge of a blade. I was hoping someone had a
chemical solution. That didn't cause problems later on - like an
aggressive flux can if not completely removed afterwards.
