I need some help figuring out what is wrong with this car.
2013 Mazda CX-5 / 2.5 engine / ~215k miles
I purchased the Forscan lite app, but it did not help me.
Issue #1:
The low tire pressure light stays on even when the tires are properly inflated, even the spare.
I believe, from my research, this car does not have TPMS sensors and uses the wheel speed sensors to determine whether a tire is low or not.
Is there an app that will tell me which sensor is bad? I could not figure this out with Forscan lite. I don't feel like changing every sensor if only one is bad.
Issue #2:
P0303
Moved the coils around, nothings changes.
Bought 4 coils and swapped. Nothing changes.
New plugs. Nothing changes.
I am leaning towards a clogged/bad injector or carbon buildup?
Who cleans DI injectors? Can I send them to RC Engineering or do they require special equipment?
Any pointers appreciated so I can return this car to its owner and get it out of my garage.
Below are some screenshots of the ABS errors that are probably causing the low tire light to go off:
