Hello,
Driving yesterday, I popped a P0420 - Catalyst system below efficiency threshold code (2018 Ram 1500 Eco)
Up to today, all was going well with the truck since I replaced the intake and switched to MR tune Stage 1, this past summer.
I pulled freeze frame data, I and It seems to look fine to me, but I am hoping to get opinions form others here who are more familiar with the numbers then I am:
1655 RPMs
67.45% Calculated Load Value
Barometric Pressure 30.12inHg (14.79psi)
Exhaust Pressure Bank1 55.9inHg (27.5psi)
Delta Pressure 2.98inHg (14.79psi)
Key on, engine off Exhaust Pressure 33inHg (16.2psi)
(For those that want to tell me to delete, can't do it, my state requires not only an OBD2 plug in, but a visual inspection. Trust me, I wish I could)
The truck is stock (other than the tune), and has about 110,000 Mi on it
