P0420 permanent

P0420 is a trouble code that is stored in your car engine control module when it recognizes a problem with the catalytic converter's efficiency. This means that something in your car's emissions system has failed and probably needs to be replaced The P0420 Code indicates that your car's computer has detected underperformance from the Bank 1 catalytic converter. Bank 1 refers to the side of the engine that houses the number one cylinder. The opposite side of the engine is Bank 2 The PCM needs to see a slower switch rate from the downstream sensors as compared to the upstreams. Basically, the downstreamers should see less hydrocarbons, more oxygen and therefore put out a lower voltage than the upstreamers. The PCM compares this ratio and will set the P0420 if the minimum isn't met When check engine lights are scanned, a p0420 code is a very common result. It's actually a generic code, meaning it can be thrown from any vehicle after 1996. Commonly, people think the p0420 code indicates that the oxygen sensors need to be replaced, but that's definitely not always the case. p0420 Code: Time to Replace an Oxygen Sensor
