Obdii Error Code P0420

Contents

(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 slightly different depending on the model. So this engine code article po430 code 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 p0420 toyota 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 p0420 ford 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 (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 spark timing The oxygen sensors in front and behind the converter are reporting too similar of readings Leaking fuel injector or high fuel pressure Cylinder misfire Oil contamination Possible Solutions Some suggested steps for troubleshooting a P0420 error code include: Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required. Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the cata

For subscription information call 800-274-7890 or visit www.mdpublications.com. Upon the arrival of the Onboard Diagnostics II (OBD-II) system, I remember thinking to myself that this new system was http://www.easterncatalytic.com/education/tech-tips/the-misleading-nature-of-the-po42o-code/ going to be the greatest thing to happen to vehicles since I had started working on them. Now all I needed to do was plug in a scan tool, since all vehicles would have the same data-link connector (DLC) much to my delight again, and the car would tell me what was wrong with it. Sadly, it was only a few weeks later that I learned that this new system was still only a guideline and not a complete diagnosis. Throughout the years, after the start of OBD-II, it has become more and more accurate, but it still requires a bit of investigating after retrieval of the diagnostic trouble codes (DTCs). The P0420 code is no different. Here is a scenario: A customer pulls into the shop and says, “My check-engine light is on.” I tell them that I will scan the vehicle and find out what the problem is. Once I hook the scan tool up and navigate through the setup menus and click on display codes, I see P0420. Then I click the display code data and the scan tool says “Converter efficiency below

I've had a Check Engine Light on for quite some time now, P0420.You have a small window of opportunity to do this, and you will need an OBDII Scan Tool that will show you the readiness monitors and their status.If you have a P0420 code, this could be caused by a number of different things. Mainly it will indicate that the reading of the rear O2 sensor is very similar to the front O2 sensor. This could be due to a bad O2 sensor (front or rear), faulty wiring to those sensors, or worse, a bad catalytic converter or ECM.When you use a scan tool to reset the check engine light, it resets all the monitoring systems as well. As I had only one system monitor down (Catalyst Control) but the others running, my car had no code an
