Hello all!
2019 F150 XLT 2.7L EcoBoost with 53K miles.
P0420 Code only. No other codes. Spray cleaned all sensors. Exhaust is not leaking. Thoughts help?

Have you checked the other possible causes of the P0420 code?

My old 2008 nissan sentra base (153k miles) always has this code, but a bottle of catalytic cleaner will remove it (with code clear) for around 200-300 miles, did this twice for emissions and all passed. Btw, my car consumes a lot of oil, which i believe is the cause of p0420
