Had some issues with the rear muffler, but that one was replaced for a original one by the dealer. New muffler sits under the car for about a month now, but i saw the P again last week.

The P Toyota code is a common diagnostic trouble code DTC that indicates a problem with the catalytic converter in a Toyota vehicle. This code specifically refers to Bank 1, which is the side of the engine where cylinder 1 is located. When this code is triggered, it means that the catalytic converter is not performing its job effectively, resulting in higher emissions. Dive into the depths of the P code, and you might find it shares a common language with Toyota. Speak the language of diagnostics. It is typically triggered when the oxygen sensor downstream of the catalytic converter detects a reduction in its ability to convert harmful gases into less harmful substances. This reduction in efficiency can be caused by various factors, such as a failing or damaged catalytic converter, faulty oxygen sensors, exhaust leaks, fuel system problems, or engine misfires. The catalytic converter plays a crucial role in reducing harmful emissions by converting toxic gases, such as carbon monoxide and nitrogen oxides, into less harmful substances, such as carbon dioxide and nitrogen. When the catalytic converter is not functioning properly, it can lead to increased emissions, which can contribute to air pollution and environmental damage. There are several potential causes for the P code to appear in a Toyota vehicle.
