Here are a couple of good guides to help with that. If there are any inaccuracies, or anything that you feel could improve the article, please feel free to comment or message. Thank you. The software in your vehicle believes that the catalytic converter is no longer doing its job.
Here are the typical symptoms that something is wrong when you have code P Mileage- May or may not suffer depending on how much the catalytic converter is clogged. Loss of Power — It is a really strange feeling to drive a vehicle with a catalytic converter that is going out. Oxygen Sensor — The P codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings.
When the oxygen sensor is bad, it can cause a false reading and trigger the code. Code P indicates that the catalytic converter is not functioning efficiently and thus not reducing the harmful pollutants your Honda's engine is emitting. The P trouble code, lighting up the check engine light on your 2. A very common misconception is that a bad oxygen sensor will cause a P trouble code. This is simply not true, although it could have contributed to the catalytic converter's demise.
In troubleshooting a P trouble code, it's important that you check if one of the following issues is present:. It's important to first troubleshoot and resolve any problems that can cause the catalytic converter to fail.
If you don't, then the new catalytic converter will eventually lose its ability to reduce harmful emmissions and fail. You'll again see the check engine light illuminated by a P trouble code.
Randomly not starting could be a bad main relay or igniton switch. Not enough info is known on this issue but that would not likely cause the misfire codes. That can cause misfires and if there are problems with tight lash on the exhaust valves then the engine is likely going to need cylinder head work or replacement.
Hopefully that is not the case. Easiest way to find out what is going on is by connecting a vacuum gauge. Another problem you may have that has not come up yet is fuel injector problems. Too much fuel being passed through the injector s will cause flooding and also cause misfires which cause catalytic converter failures.
Improper fuel pressure regulation, bad fuel injectors can contribute to this problem. Or even possibly a problem with injector signal. The mechanic came yesterday before I was able to read your replies. When he started the car for a final test, I was overwhelmed by the smell of gas no wonder I blow through it and I saw lots of white smoke coming from the tailpipe. I asked him about the head gasket being the possible problem.
He ultimately thought it was the head and head gasket, although before leaving mentioned there could be a slight chance the radiator cap could be the culprit. Given how many problems I have had with this car and how unreliable it has been and how unskilled I am with cars, I am leaning towards his latter suggestion.
No…I have not done this, nor have I seen a mechanic or anyone else who has added coolant to my car do this. It seems I need to learn how to do this for whatever car I have in the future.
Thank you for the suggestion. Thank you for any help! Codes P, P, and P are misfire codes. Would replacing the head gasket fix it? Any other suggestions? Thank you so much! Possibilities are external leak somewhere, but not enough to reach the ground. Thank you!
