All my sensors are fine but I still get alot of fault codes, any thoughts?
I’d check all ground points.
Hi David, how old is your battery ? I was getting quite a few fault codes myself about 5 months ago, I spent weeks tracing and testing each component indicated to be at fault only to find it was functioning perfectly, I also cleaned up all the grounds I could find. My battery was around 5 years old but would start the car without fault and seemed to hold a good charge so I ruled that out as the cause but once I’d fitted a brand new one the problem ended and I haven’t had any codes since.
Battery is only a couple years old, are there a lot of ground points under and around the dash?
Is there a common ground point for all the fault sensors?
