Title: Lambda Sensor
Post by allenjames on Mar 23^rd, 2007, 11:11am

Just looking for a new lambda sensor to go after the cat.

the ones on cats direct are solder in types I guess...

Are they easy to fit ?

Have a look Here (http://www.fordscorpio.co.uk/ho2smonitor.htm). Scroll down and it details a four wire.This (http://www.gendan.co.uk/product_LB1335.html) site shows the direct fit one but you can check through and find cheaper ones.

I just need to know which wires on the car match the lambda.

hi there

is this on the new lambda sensor? the 2 wires the same colour are for the heater. the other 2 are live and earth. check with a meter set for 1 volt.

are there no instructions with the new sensor?

car wiring on page 9 (http://www.carsoft.ru/avtorepair/sierra/engcntrl20.pdf) for car colours

thank you.

I have finally cured my lack of power at 4500 RPM - the cat brick was busted blocking the exhaust.

New cat, lambda sensor and manifold (as its frikken cracked) and I should be good to go.
