I have recently purchased 3 universal sensors for my Gs300.

However the heater element resistants is not the same as the standard. I believe it is meant to be about 12-15 ohms.

The ones i have bought are less.

Will this matter?

Anyone know???

They are still narrow band and will fit.

How much is the variance and is that measured off an old sensor?

It could be that the heaters on the old ones have increased resistance due to heat and ageing.

The manual says it should have a resistance around 12-15.

Not sure if putting in 6ish ohms will knacker the engine

Sounds well low as each will draw double the current so not too sure really, all I can say is that I put "generic" ones in mine and had no problems.

I changed for OEM ones and just had the "generics" till I got the OEM ones, if I get a chance I will meter the installed ones, and the "generics" (if I can find them) at the weekend.

I have checks 2 types of universal fit sensors and they both have the lower resistance.
