    Default Help Needed

    Hi guys. I have a 53 reg Edition 100 2.0T SRi.

    Driving home this morning i stopped at the lights and have had a light come on the bottom right hand of the dash. Looks a bit like an engine.

    Have done the pedal test and it gave me the code 0420. Checked all the posts and it shows that it is something to do with the emissions so assume its the lambda sensor. Does anyone know if there is 1 or 2 fitted to the car and if 2 which one it is likely to be and has it only happened as it was -11 this morning.

    Cheers

    Vehicle : Honda Civic

    Trim : ES with Honda Image and City Packs

    Engine : 1.8 iVtec

    Year : 2009

    Mileage : 85000

    The light is the Emissions light, normally there are 2 lambdas fitted, position 1 the one at the manifold, position 2 the one after the cat. Maybe the cat starting to fail. Code will disappear after 10 days, then if fault still there reappear. Maybe it just requires an "Italian" tune up IYKWIM?

    Had the same code come up on mine during heavy snow 3 weeks ago, didn't go out so i bought a code reader off ebay and cleared the codes, up to now 1 week later still hasn't reappeared so fingers crossed.
