I hope your diff is in good condition, otherwise the run-out will crash the sensor and it will fail fairly soon. But if the diff has been refurbed recently then you should be fine.

It's at least 8 years since I fitted and gapped my new sensor at 6 thou'
It's still working perfectly.

It's a new diff, fitted by a specialist at significant cost. Although it has already started leaking oil, so not very impressed.

yikes

Are yours still available, linky smile

My speedo reads 40 mph when stationary some days, others it's within 15 mph.
It's time I sent my clock to be repaired but a new speed sensor would add to the hope I'll get a reasonable speed readingbat some point smile

Yes, still available. But to be honest that is not the usual sensor failure mode, so I would be reluctant to claim that a new sensor will stop your speedo overreading (or perhaps sticking?)

If you're getting the speedo repaired then you may find there's no problem with your sensor.

The usual issue is that the sensor will become unreliable, and then fail completely shortly afterwards, meaning no signal reaches the speedo, and no speed (or mileage) is recorded.

The OEM sensors are not as sensitive as the replacement, so they get damaged more easily by run-out on the diff because they have to be so much closer to the reluctor ring.

I'm away for a couple of weeks, but if you are still interested in a new sensor just PM me your address, earliest it would be with you is Tuesday 17th.

Thankyou for such an honest answer.

It's because yours is more sensitive I thought I'd ask smile

Mine is predominantly the speedo at fault and it still works (in a fashion) so the sensor is still active then.

I've lived with it for 5 years,,,
I'm superstitious or daft enough to believe if there's maybe just one or two things wrong with a Tvr it's perfectly normal
Fixing it to the point it's errr fixed will enrage the Tvr gods and that risks total stunt down of all systems hehe

I'll keep your details and when I brave the wrath of the gods and actually get the speedo repaired I'll likely have a sensor off you then anyway.
Thanks Alun.

How about a second-hand speedo unit from a breaker ? Might be cheaper.

Off Glen, I'd rather eat wasps hehe

I like the idea of keeping my car original as possible so I'd rather keep my speedo and it's milometer reading as it is if possible smile

First thing I did some years ago was buy a used sensor from a South West based breaker which cost £40 inc. Needless to say it didn't work. That's why I decided to source a replacement with the hope that others might benefit as well.
