TPS substitute.

Got a flier from Rapid Electronics, with something of interest for here.

Vishay electronics produced the RV8 TPS replacement that some on here have used, but sourced through RS Components. It seems to be an obsolescent part as is often out of stock.

Vishay have produced a hall effect rotary position sensor which looks physically similar. Being hall effect, there is no track to wear out or get dirty - and shouldn't be effected by water. Life is said to be >10M cycles. Costs £39.50 + VAT.

You can download a PDF from that page giving the full spec.

Has anyone used this type of TPS with any success?

Thanks,

Jim

Looks like it would be spot on with MegaJolt or MegaSquirt. Not sure if the calibration is close enough to the standard EFi TPS though to work OK with that.

Sorry - should have posted a follow up. I'm told none of these are suitable.

The RS Components one is still available, though. That does work with flapper injection.

http://uk.rs-online.com/ and put 319-310 in the search box.

Hi

Thanks for the reply, so the RS part code 319-310 will be fine with my 3.9 EFI 14 CUX, Lucas 5 AM maf?

Sorry - don't know if it's ok for a hotwire. Anyone know what the resistance of the hotwire one is?

How do you go about replacing a resistive sensor with a hall effect sensor? They work in completely different ways and the outputs are totally different.

I dunno exactly how these solid state pots work - but they produce a varying output voltage just like a normal one, but without the track and contacts to wear out.

Looking at the data sheet its output is a pulse/PWM the same as any other hall effect sensor. It will only do this while moving as well. Think crank sensor or electronic dizzy pickup. The outputs are basically the same.

I have looked at the data sheet again and there are 4 models 2 of which have a linear output. No idea how they get that from a hall sensor without some other interface.

Hall effect sensors already have electronics, so I'd guess they've just added more. It's quite a pricey device.
