Lambda sensors
 

just wondering where the 2 lambda from the exhaust plug into the engine area,
ive had to get a mani and cat for mot and it has 2 holes for sensors, one in the cat and one in the mani itself, and need to figure out if i need both or its just the manifold one i need to use. 2000 vtr silver top
cheers :y:

It depends on Mk.1 and Mk.2 engines. Are you sure you have got a direct replacement to the one you have taken off? Mk.1 (single plug ECU) only has 1 sensor, Mk.2 (3 plug ECU) has two - pre and post cat. To save you the hassle of going back you could just get a lambda blank off piece, or just put an old lambda in the second hole if you have got one spare? I would still check it's the right part for your car first of all :y:

thats the thing what i took off was just a manifold and downpipe with the triangler flange, it had no cat on the car. it has no sensor hole in the mani and one in the downpipe.

ahh just re-read the post, mines a mk2 single plug, so should only need one sensor.

Yeah.. you just have a downpipe with a hole for 1 lambda sensor in that. The cat is under the car and doesn't have a post cat sensor. If you have gone and bought a (more expensive) cat which is part of the manifold, then change it for the single downpipe. :y:

not too fussed cos the the mani and cat i bought was 2nd hand for 50 notes, i can sell that on,
so when i get the proper exhaust set up i should only have 1 lambda sensor which would be where?

At the front of the engine as you look at it, just behind the radiator fan. Your sensor should bolt into the downpipe there.

cheers mate :y:
