Code P0037
Can someone please help me and tell me which 02 sensor is Bank 1 sensor 2 o my 2005 rx8?! There’s one before the cat converter which it looks like a pain in the butt to change, and the other one is on the actual cat. Which one do I need to change to fix code P0037. Hope someone can help me here. My car is running super bad, idle super rough when cold motor, and almost no power to take off. Also the emissions are terrible. |

P0037 is the rear O2 sensor in the cat. However, that is unlikely to be the cause of your problems. Before you do anything (including drive it), remove the 3 bolts connecting the front of the cat to the exhaust manifold. Pull it down and shine a light in there to see if the catalyst bed is disintegrating. Until you verify that your cat isn't falling apart and clogging up your exhaust, you should not drive it. A clogged cat will destroy your engine which will cost you $3000+ to properly repair (if that hasn't already happened). If you cat is clogged, you should check your ignition components since the most common cause of a dead cat is misfiring from bad coils/plugs/wires. |
Thank you for your quick response, it can’t be coils/plugs or wires bcs I changed all of that. That Cat though... that might be an issue. But last year I took it to get it looked at and they told me it was still working properly. Still I will check |
Just because you changed them doesn't guarantee that they are working.
