I had a CEL with code P, so I unscrewed the downstream O2 sensor, blew it out with compressed air and screwed it back in. That cleared the CEL. Total time was about 15 minutes, including setting jackstands to get underneath the car and disconnecting the battery to clear the light. Sort by Oldest first Oldest first Newest first Most reactions. Let us know after a while if it continues to no longer have the P I was hoping it was just fouled from burning oil. Any suggestions on the next step? Bad sensor or bad catalyst or something else?

Thanks for the replies so far.

The P trouble code in a Toyota Prius is typically triggered by issues related to the catalytic converter and emissions system. Over time, the converter may become clogged or inefficient, leading to an insufficient reduction in emissions and triggering the P code. Additionally, exhaust leaks, damaged oxygen sensors, or faulty engine components can also contribute to the appearance of this trouble code. Oxygen Sensor — One can expect the code thrown when oxygen sensors on both sides of the exhaust display akin readings. The p Toyota Prius trouble code can trigger when the oxygen sensor is bad and displays a false reading. If the engine does not display any of the decreased performance related to a bad catalytic converter. A bad oxygen sensor can also be a problem.

P is a well-recognized error code within the automotive industry, notorious for its persistence. Luckily, this article is designed to guide you through understanding the implications of this error code, exploring its possible causes, and navigating potential fixes. Drawing on our experience, we acknowledge that resolving P can be challenging without appropriate knowledge. This complexity arises as the error can take a significant amount of time to reappear, even after parts replacement and code resetting. Throughout this blog post, we will address these issues and more, providing you with comprehensive insight into the P code. This could be attributed to a malfunctioning catalyst or potentially be a false alarm triggered by a defective O2 sensor. The engine control module ECM uses two O2 sensors, one in front, and one behind the catalytic converter to measure its efficiency. If the catalyst system efficiency is low, the P code will be triggered.

Contact fixmycar. The oxygen sensor after the cat tells you if the cat is good or not. Show Ignored Content. Thanks for the replies so far. Post Reply. Flare paint protection. No, create an account now. WhatsApp us. If it's sensor 2, swap the sensor to the other side bank 2 and see if the error tracks. Just drove 4 hours and no more codes popping up. By facilitating the conversion of carbon monoxide, nitrogen oxides, and hydrocarbons into carbon dioxide, nitrogen, and water vapor, catalytic converters significantly contribute to improving air quality and mitigating the adverse effects of vehicle emissions on human health and the ecosystem. Thus a damaged O2 sensor wiring can cause p Toyota Prius trouble code. JavaScript is disabled.

This page is meant to help you troubleshoot the Toyota Camry P trouble code. A failing oxygen sensor or bad catalytic converter are the most common causes of P

Moreover, they are essential in meeting stringent emission standards set by regulatory authorities worldwide, ensuring that vehicles are more environmentally friendly. Toyota Union - Rangergillikin , Nov 26, I've searched but not found a specific thread for this. I was hoping it was just fouled from burning oil. Thank you. In essence, catalytic converters are indispensable components in modern vehicles, serving as a crucial line of defense against air pollution and promoting a cleaner and healthier atmosphere for everyone. I was getting the same code. If the engine does not display any of the decreased performance related to a bad catalytic converter. Tundra2 , Oct 25, IE, are there 4 o2 sensors on the truck?
