The P0420 code in a Toyota 4Runner will often be thrown if one of your vehicle’s oxygen sensors is not functioning correctly. There are rarely drivability issues associated with P0420. For most people, the first sign that anything is wrong is the service engine soon light coming on.Got a CEL today. Ran the code and it's P0420: "Catalyst System Efficiency Below Threshold (Bank 1)". This is usually an issue with the cat or o2 sensors. Good news is my car still is under 5 year/60k powertrain warranty. Strange thing is my car only has 27k miles and nothing should be failing on this car, especially the cat or an o2 sensor.

Downstream – The downstream oxygen sensor’s (after the exhaust exits the catalytic converter) primary function is to verify the catalytic converter is doing its job. Often, an oxygen sensor is the cause of P0420. When an oxygen sensor has failed, it can cause a false reading and trigger this code in your car.Code P0430 Ford Description. The Engine Control Module ( ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor). A three-way catalyst converter (Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2.Tom Harbid. If you're searching for how to fix the P0420 code, your problem is most likely related to issues with the catalytic converter. Since the catalytic converter is very expensive, before you replace it, check issues with other components like the oxygen sensor, the muffler, the exhaust pipe, the manifold, or the oxygen wiring.Code P0420 Chevrolet Description. A 3-way catalyst controls emissions of hydrocarbons, Carbon Monoxide (CO), and Nitrogen Oxide (NOx). The catalyst within the converter promotes a chemical reaction, which oxidizes the hydrocarbons and the CO that are present in the exhaust gas. This process converts the hydrocarbons and the CO into …

Tech Notes. As the code description implies, the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases, the catalytic convert needs to be ...Then set torque to display the O2 sensor outputs. You should then be able to see the levels cycling. Next step is to swap the offending sensors, (downstream usually), left/right & see if the fault stays on the one side, (bad cat), or swaps over, (bad sensor, much cheaper). I had this & it was a bad cat in the end.Code Tech Notes. As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting).
