PO420 error after accident?
hello all
Unfortunately, I was rear-ended a couple of weeks ago. Yesterday my Service Engine Light came in and I checked the code to find the PO420 Catalytic System below threshold bank 1.
Any my chance this is related to the damage in the rear? Or unrelated O2 sensor or Catalytic Converter problem??
Thanks.

I suppose the exhaust could be damaged in a way that causes an obstruction?

I appreciate your friendly advice. I took the vehicle to 4 bodyshops for estimates and none put the car on a lift. I have never seen one do that during an estimate, but I have never had much damage to a vehicle either.
The SEL light had not come on when I was getting the estimates so there was no discussion of that.
As of now the light has gone out and not returned so I’m not sure what the issue is but I will mention it when I take the car in for repairs next week.
