dose my 1.6 ford focus have 2 lambda sensors?
dose my Ford Focus 1.6 2004 have 2 lambda sensors? I asked my local unipart dealer for a price for a new lambda sensor but I was told there were 2 listed for my car, Front and Rear. there is a lambda sensor on the front pipe before the cat. I can only imagine the "rear" one is after the cat.
the car broke down a month ago, the coil packed in and the plugs were burnt out, thats what prob what cooked the coil, weeks later the ecu light came on and stayed on, I got it cancled, the code showed it was to do with the lambda sensor. a few weeks later it came on again for a few days, I gave the car a serious blast for a few miles ie 85 in third up and down the gears ect... the next day it stayed out. so far so good.
Ho dear the light came on again yesterday, and is staying on. I was sitting with the engine idling for about 15 mins dont know if that had anything to do with?
the light went out yesterday when I started up to drive home from work, I did'nt do anything diffrent on the way to work, just the usual cruse along the moterway. hope it stays out for good this time.

The sensor in front of the converter could, as you suggested on your question, selection. The sensor at the back of the converter is a catalytic converter video show, and if the converter is working exact, this sensor won't selection virtually as plenty, if in any respect. fairly plenty any O2 sensor that "reads 0" after the engine is at working temperature is defective and needs to get replaced.

Yes there is one before the catalytic converter and one after it. Whats the reason for renewing the part?
