A couple of months ago, I first noticed an exhaust leak coming from the catalytic converter area. Didn't think anything of it; no CEL, no effect on gas mileage, just a little noisy. I still don't know if this leak plays a role with what I'm experiencing now though. Coincidently now, my bottom catalytic converter heat shield had corroded away at the 4 bolts on points. So when driving home, I drove over a snow drift, it knocked the heat shield off, and since the rear oxygen sensor is guided through the heat shield, it must have snagged on the oxygen sensor cable. All at once my ABS, VSA, !, and CEL came on as well as a flashing D5 light. The 4 codes it threw were P1298, P0135, P0141, and P1768 all at the same time.

First thing I noticed was driving from a stop seemed extremely weak and slow unless I manually put the car into D1 or D2. When in D3, D4, or D5, it must only go into 4th gear I'm guessing and doesn't shift gears at all for that matter except for when I manually put the car in D1 or D2.

I replaced the rear oxygen sensor thinking that was the source of my problems since the heat shield yanked on the cable, but this did not fix the issue. Any ideas? Thanks for any help on this issue!

 

Since the vehicle was still drivable to a degree, I needed to take it to the local dealership to get an airbag recall done. Been needing to get that done for like 2 years now and of course, these problems happen right before my appointment. When I pulled up to the dealership, the oil light started flashing on top of everything else already going on. I think a flashing light means faulty oil pressure. So I definitely didn't want to drive it back home. I left my car there and Honda will be doing a diagnostic test on it. More details to come for anybody interested.

 

Car is fixed! Had the dealer do a diagnostic test and a 5th code came up too, that being P0700. It all turned out to be just a blown out 10 amp ECM fuse. If I had my car for just a little bit more time, I could have easily found that myself. But didn't want to risk damaging the engine with a flashing oil pressure light on. But now you know what happens when this fuse is blown out!
