Today's pretty cold here around -15C+ with snowstorm and on top of that windchill.
I was on the highway trying to beat the after work traffic and tried to get ahead of a snowplow like all the other cars.
Dropped into 4th and accelerated while trying to avoid all the rock salt spray.
At this moment, while I was running over these stuff, my CEL came on. I went home and read it with Torque.
It's all muddy wet in the garage right now so I cannot get under the car to look at the the cat.
Pending P0420 code which means possibly something wrong with the cat.
Car is Honda with K20 engine with ~303000 km now. Never changed the O2 sensors.
As far as I know, there are 2 sensors B1S1 and B1S2. I cannot read the B1S1 voltage, but I can see B1S2 through Torque.
1. Is that normal?
2. Why all of a sudden this code pop up just because I did a bit more acceleration in the 4-5K rev range?
My cat heat shield is pretty rusted out with lots of holes, I have 3 hose clamps holding it together so there's no rattles.
3. Is a cat very easy to damage by road debris?
