Thread: Need Help with P0106 and P0420 codes!!

you can get that $93 MAP sensor off ebay for $13. bad o2 sensors can give a p0420 code. I would change both o2 sensors and the MAP sensor, you can get all 3 for less than $60 on ebay. . As for cleaning everything run some SeaFoam thru it and start using Lucas gas treatment.

Thanks. Yea they must think I was born yesterday. I wont be going back to a dealership ever again thats for sure.

Its code P 0106

Thanks for the info.

Personally? I would replace the front o2 if it is more then 60k miles or 5 years old and then do the non fouler trick on the rear o2. You don't need a o2 sensor to tell you when your cat is going bad. Trust me you will know because your car will not go over X mph. Also ignore all of that cleaning bull****.

Thanks for the info. The car only has 52,000 miles on it so i will start first with replacing the Map sensor and see if the code clears. My car is driving fine and my gas mileage is still the same

Don't cheap out on the MAP sensor. Go OEM. I got mine at NAPA for about $90 something and installed it at the stealership parking lot cuz they wanted to charge well over $300 to switch it out (I got ran off the lot for doing work on the premises haha). My mistake was getting a cheapy one from Oreilly's and I never would have guessed it was the MAP sensor. They diagnosed it for me though.

Clean the old map and check the cable first before buying a new one. There's guide on safe cleaning but dirt or dead bug stuck on the map can throw bad map. Check the intake air filter if it was dirty map.

What problems was your car giving you other than the check engine light staying on? Actually I am not having any mechanical problems right now my car still drives fine.
