CR-V OBD Codes

In Dec my 03 CRV got P0845 and P0420 code for the first time. Its the first time I seen an engine light on. I had 157K miles in it.

Took it to the dealership and they fix the P0845 and cost $170.

They clear the P0420 and it last week it came back. The dealership clear it again and after driving 50 miles, it came back on.

I am going to visual check my exhaust and unplug/plug the 02 censor tomorrow.

Next month I need to do my emission test.

1. Is there anything else I can do?
2. Has the cat converter reach its shelf life?
3. Dealership said cost 1K to fix. I dont mind the fix, but what if thats not the problem?

Your advice?

Thanks!

    You are not going to believe this.

    The reason my car is throwing those P0845 and P0420 code is because my car is burning oil because of old age of 153K now. As soon as I put in 1 quart of oil, the light goes away and I just pass my emission test after driving it about 100 miles.

    BTW, when I went to the dealership the 2nd time, the guy that reset my code says this P0420 code for CC is common! Imagine how easy to get rip off by anyone!

    What does this tell you? Never trust OBD code! So I dont know what to believe now!

    Any advice?

    Probably a dribbling fuel injector. Either needs to be cleaned, or replaced. First try a bottle of Chevron with Techron concentrate in a full tank of gas.

    Also, when driving, try to not to shift below 5000 RPM, this will get the injectors working and will clean then out, along with the Techron fuel injector cleaner.

    If all fails, you will need to replace 1 or all 4 injectors.

    Oh, and is the code that set of the Check engine light?
