and i need a lambda sensor .. i have a boss welded in the exhaust so thats not a problem ..
what i was wondering is what sort i need 1,2,3,4 wire ? ..and as i only need it for the LPG thingy does it need to be powered or are they self powered by the interaction of the gases ????

Thankyou

ps: in the diagram in the listing , where does the Grey wire go ?

I'd use a heated sensor just simply for the fact that it will get up to temp quicker.

Some wire colours here:

(Can't see the listing as internet here at work is totally locked down- except v8forum

)

LPG / LAMBDA Help please

I have bought one of these :
http://www.ac.com.pl/public/pubonline/c ... manual.pdf

i have a TITANIA sensor with RED/BLACK/WHITE wire on it ....... but its not connected to the vehicle ecu because it dosnt have one as Std .. so it will only be used by the LPG Control unit ...
and im getting stuck on wiring it up

the instructions are not the most helpful on this so any help would be great ..Thankyou

I'd say you need to use the one specified by the LPG ECU supplier.

If this is impossible, there are wideband ones (with their own electronics) with a programmable output which could be set to pretty well any requirements. Costly answer, though.

Thankyou Dave

....

the sensor i have came off a volvo 940 and i managed to find a wiring diagram for one and the only connections i can see are .RED = power for the heater , BLACK = earth ( signal & heater ) & WHITE = signal

it just depends on output ...which i may be able to check with a volt meter once its fitted and running before connection the control ECU ??

what do you think Dave ?

Not got any experience of LPG. The figure I have for petrol is 0.45v at stoichiometric. But that's from the MS site - I'm not sure they cover all types of sensors.
