If no excessive catalytic converter temperatures are found and the exhaust backpressure falls within acceptable limits, it is almost certain that the converter has failed due to long use. This can be confirmed by the fact that its temperature remains below deg F deg C even after expended periods of driving.
As stated elsewhere in this guide, replacing a catalytic converter almost always requires equipment and skills that most non-professional mechanics do not possess or have access to.
Thus, if a defective catalytic converter is diagnosed, the better option is to refer the vehicle to a specialist exhaust fitment shop for professional assistance.

A few weeks back, it was only P that was stored in the ECM. I just bought a new O2 sensor,hoping to have it replaced only for me to realize the 2nd code.
Is the P as a result of bad O2 sensor? Will replacing the O2 sensor alone clear the P code? I already have a replacement O2 sensor. Hamed: It could be with the P code. Were you able to test that circuit? You need to test the sensors. It is not a good idea to throw parts at the problem without testing 02 sensors. Basically, after the engine cooled down to warm, he removed the upstream 02 sensor bank 1 and sprayed sea foam into the hole.
After he reinstalled the sensor, he started the car, which produced a plume of white smoke. When the smoke cleared, he cleared the code and never seen it again.
I did the same and it worked but after driving a week and a half continuously and oil change, the P code came on. Fuel injector failure, replaced injectors, upstream and downstream sensors now throwing p catalyst below threshold. Is it likely that the failing injectors resulted in this? Any suggestions on how to proceed with diagnosis? You might be able to salvage it with an Italian Tune-Up drive it like you stole it. Make sure to check for other things skewing the oxygen content of the exhaust stream, though, like defective exhaust gaskets, rusted-out flex pipe, or rusted seams.
Counterintuitively, each puff is followed by suction, because of the way exhaust pulses in the exhaust. Congrats on pushing your Camry past the typical service life! Judging by the age and mileage, P could be caused by an exhaust leak, lazy post-cat oxygen sensor, or spent cat.
Hej, I trying to solve the problem for aygo, km, first time I got motor lamp shine, and it was Code P B1S1, after one week this code dissappear and it comes p, and finnaly after 2 weeks I get P permanent code I erase that and change spark plugs because it was looking very bad, so we drive like 2 weeks without any problems but now code come back again, I erase it again so i dont know when the code comes back again, car is using basically just in city driving, so maybe I can get some tips?
I check O2 sensors and cables , heater resistans too, intake leaks, exhaust leaks, everything was looking good so I hope so to get some advice? A week in a half ago, I had the P code only.
I watched a YouTube video where a mechanic had the same code on his vehicle. In short, he removed the upstream 02 sensor, while the exhaust system was fairly warm, and sprayed sea foam into the bung hole of the 02 sensor. He let it sit a good hour or so after he reinstalled the 02 sensor. After the vehicle sat for an hour, he started the car and a huge cloud of white smoke came out until it cleared.
He commented that this procedure has help many of his clients… So I gave it a try, following the procedure. I noticed that the p code had not illuminated in over a week and a half of daily driving Uber. I went to get an oil change and in about a couple of hours, the CEL came on p I stopped driving it, bought a Bluetooth scan device and found out some readings relating to the bank 1 02 sensor 1.
I changed my cat with a bosal unit. Changed both 02 sensors and still have the p code plus misfire 1,2,3,4. Log in Register. Search titles only. Search Advanced search…. New posts. Search forums.

Thread starter switters Start date Apr 28, Called the dealer and they told me to bring it in Monday morning they close at today and are already booked.
He said I could drive it around town if the light isn't blinking, but to pay close attention and if it starts blinking be ready to pull over. What causes this? The car only has 2, miles on it and is 9 months old. Is there anything I can do in the meantime?
The car is telling you that it needs to regen. Do a search on here there is a lot of info. You need to drive the car for twenty mins at a steedy highway speed and try to keep it above rpm.
You may have to drive in fourth or fith gear. This will hopefully start a regen.
