Obd Error Code P0420

(DTC) is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be p0420 toyota slightly different depending on the model. So this engine code article applies

to Nissan, Toyota, Chevrolet, Ford, Honda, GMC, etc. The catalytic converter is a part of the exhaust system

that looks kind of like a muffler, although it's job is very different from that of a muffler. A catalytic converter's job is to reduce emmissions from the exhaust. The

catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of p0420 nissan (among other things) a converter that is not working as efficiently as it should be (according to specs). Catalytic converters are not normally a "wear" type item, that is they are not deisgned to wear out and need replacement. If they have failed, it is likely due to something else that caused it to fail. Symptoms The main symptom to the driver is the illumination of the MIL (malfunction indicator lamp). You will likely not notice any drivability problems, although there may be symptoms. For example, if the substance inside the catalytic converter is broken or failed, it may be restricting the exhaust which will result in a feeling of reduced power output from the vehicle. Causes A code P0420 may mean that one or more of the following has happened: Leaded fuel was used where unleaded was called for A damaged or failed oxygen sensor (HO2S) Downstream oxygen sensor (HO2S) wiring damaged or connected improperly The engine coolant temperature sensor is not working properly Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe Retarded

that specific trouble code. If your car's check engine light is on, get that code read in case it's a P0420. A P0420 code is a trouble code on OBD-II equipped p0420 honda civic vehicles.

This site is here for information purposes only and is meant to help you learn more about the dtc and decide if you can tackle the repair yourself. It is not intended as car repair advice. OK, so what does a P0420 code mean anyway? As mentioned above, the code's description is Catalyst System Efficiency Below Threshold (Bank 1). OK, now tell me that again in plain English please.... let's break it down: the catalyst system being referred to is your three-way catalytic converter; so the catalytic converter is not working properly (i.e. it's not efficient). Bank 1 refers to the side of the engine which contains cylinder #1. On inline engines such as 4 & 5 cylinder engines, there is only one bank. So, to really simply things let's just say that the efficiency of the catalytic converter and/or exhaust pipe and/or O2 sensor is no

Warm the engine up until the engine fan kicks in. Then, increase engine speed for about five minutes, usually between 2,500 rpm; this will help the catalytic converter light off heat up. After this look at the wave forms between the catalytic converter front upstream oxygen sensor and catalytic converter downstream rear O2 sensors. If the front catalytic converter upstream oxygen sensor wave form is switching from high to low (rich to lean) and the rear catalytic converter downstream oxygen sensor is close to a straight line, the original converter should be good. If the rear cat

When your check engine light comes on with a P0420 code, that can mean only one thing - an expensive trip to your auto mechanic. The P0420 error code is a sign that your catalytic converter is under performing. That could mean it needs to be replaced or just possibly cleaned. The good news is that we've uncovered the easiest ways to fix those catalytic converter problems so you can get back out on the road without spending a fortune. Quick ways to fix a P0420 code: Check the exhaust system for potential leaks Use Catalytic Converter Cleaner to remove any build-up in the system Fix or replace damaged oxygen sensors (special tool required) Replace the catalytic converter Before You Replace Your Catalytic Converter, Try One of These First: Editor's ChoiceBest GuaranteeBest Price Mr. Gasket Cataclean Fuel and Exhaust System CleanerCRC Guaranteed To Pass Emissions Test FormulaSolder-It (CAT-1) Catalytic Converter Cleaner 3.5 out of 5 stars4.0 out of 5 stars3.5 out of 5 stars What does the P0420 OBDII error code mean? Whether you want to call them OBDII (on-board diagnostic) codes, diagnostic trouble codes, error codes or check engine codes - they all imply the same thing: you’ve got car trouble. In your case, the P0420 code stands for "Catalyst System Efficiency Below Threshold (Bank 1)." When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors. You may not notice if you have catalytic converter problems but the environment will. A catalytic converter helps reduce your car’s emissions. It does this by converting the carbon monoxide in your exhaust into carbon dioxide and water. If you continue driving without fixing this problem you may not pass your vehicle emissions test or smog check. See also: Catalytic Converter Replacement Cost Do I Need a New Catalytic Converter?
