Getting Lambda Sensor Wired Up

[Karl 15 1 Cars]

so after a week of dodgy wiring and changing gearbox clutch and upgradin flywheel all is now well...............i have read somewhere a lambda will make my car run better so i want to get this sorted can you help me get my lambda wired up what do i need and what i need to do many thanks

assuming you even still have the plug on your loom, itll be very easy for you. just weld boss into exhaust, screw in lamdba and plug it in...

[Karl 15 1 Cars]

cant weld is there a hole there already only i could complicate what seems to u an easy job lol

[Miles 331 1 Cars]

Unless your lucky no, Any exhaust place should be able to weld a boss on for you thou

[petert 601]

What engine/ECU do you have?

[pug_ham 245 3 Cars]

The GTI-6 loom should have a lambda plug already in it.

What engine/ECU do you have?

yeh ive got a gti6 engine and ecu both standard but have a kand n air filter and a lightened flywheel

got my mot comin up on thursday so have arranged for them to weld a boss on for me at £60

 

The GTI-6 loom should have a lambda plug already in it.

yes ive got the little 1 inch black lambda plug already wired in

 

what diffrence wil lthis make to my car anyway lol will it make it faster?? lol

[Miles 331 1 Cars]

£60.00, ouch, a Stainless boss is around £8.00 and welding one on takes all of 10 minutes

 

Just make sure you have a live to the sensor

[Alastairh 47]

Just make sure your plug hasn't been chopped off and that you have ignition live on the connections.

[Karl 15 1 Cars]

well all the wires are going to the plug from ecu im assuming one of these will be a live ??

[Miles 331 1 Cars]

The live goes from the Fuse box normally where it has a separate 10amp fuse in a 306

[petert 601]

O2 sensors also have their own direct fused supply in 205.

[Karl 15 1 Cars]

this is a phase 1 205 will it still be the same??

[Miles 331 1 Cars]

205's never had them in the UK until 1992 on, So no yours will not but just check for 12v's at the plug, if not then I'd say also the VSS is not connected up either

[dcc 855]

tbh your loom should be intact. as long as you have the 4 wires connected as per my reply in one of your other threads you will be fine.

 

if you really have no idea what you're doing, take your car to miles or somebody else who knows what to do and wont melt something...

[Karl 15 1 Cars]

lol would love to take my car to miles ............... im ryt on the humber miles is near southampton kinda long way 4 a lambda

[Miles 331 1 Cars]

LOL, I've had people from all over the UK and a couple from Europe before so your almost classed as local

[Karl 15 1 Cars]

in that case yes i am lol......... looking at lambda sensor plug seeing 4 wires going into ecu loom where would the live go as there is no more pins free.....

 

1 green and yellow - earth?

1 red - live

2 otheres tht cnt remember lol

[pug_ham 245 3 Cars]

The feed for the lambda on a GTi-6 is from the double injection relay via the inertia fuel shut off, earth is through the ecu pin 17 to battery negative / main ecu loom earth terminal.

 

The other two wires run between the lambda & ecu.

[Karl 15 1 Cars]

so i can just plug in my lambda and it will work ??

[pug_ham 245 3 Cars]

It should do but from how you've described your loom I wouldn't like to guess.

 

A few minutes with a multimeter (iirc you don't have one so that'll be a problem) will test the wires to see if there is any reason why it won't work & you can test the sensor itself to make sure its not dead already.

[Karl 15 1 Cars]

lol ok thanks the sensor is brand new so am just gonna get boss weded and plug it in n hope for the best lmao
