I can't remember my code it threw but it was only one code and said downstream o2 sensor failed to heat. I used a scanner that links to your phone and then run the app it is called torque. Scanner was 20 bucs and app was 5 bucs. My girl bought it for her 2013 fiesta but works on all vehicles back to 1996.
Those codes would more likely point to a wiring harness fault (open or short) if they came on suddenly without warning. Have you examined/traced the wiring harness before buying new parts? A curb bump on the front header downpipe can cause collateral damage, for example.
They both didn't come on at the same time, and I had my cat off a couple months ago because my oil pan was leaking. Recently I was under it replacing fog lights and I checked all the wiring from the bottom and top. Guess I could get down there with a multimeter and test a few things
whats a really good 180° thermostat replacement upgrade that will help with performance? If anyone has one that really helps could you attach a picture and brand name and stuff. Ive been doin research but cant find much. I have a 2017 focus
I have been posting for the past few days now... I know that Focus's are famous for their rough idles... However, my problem does not stop there, I am having a hard time accelerating after my car gets warm... especially on the highways, I have to have it revving in order to have it...
I bought my daughter this car a little under a year ago and it has not been one of my better purchases. Within a couple of months of getting it, she was sitting in traffic and got a warning message telling her the car was overheating and to pull over and shut down as soon as possible...
