Cat P0420 Fiesta 1.0 3cyl
Discussion
I've got the lovely P0420 code, I know this is related to the catalytic converter and associated sensors.
The car is a 2015 Fiesta 1.0 ecoboost with ~80'000 miles.
I've had two missions tests since I purchased the car at each MOT:
08/2020
First one 2500rpm, CO, 0.0% HC, 7ppm, Lam 1.002
First one idle, CO, 0.0%.
08/2021
Second one 2500rpm, CO, 0.19% HC, 81ppm, Lam 1.021
Second one idle, CO, 0.30%.
It's 1% below fail limit of CO for the emissions test.
I've been quoted £600-1100 to replace the cat. Is this something I can replace myself? I'm apprehensive on spending that amount if it is something that I can do. If not, fair enough, but I like to do work myself where I can.
EDIT:
Used cataclean, light went off. I've driven 350miles since the light went off and it's back on this morning with P0420.
Off to the garage it goes!
