Replace it with a new one.
How do you fix code po420 for Chevy s10 blazer?
P0420 = Catalyst Efficiency Below Threshold (Bank1). Sounds like you probably need to replace the Bank 1 (drivers side) Catalytic converter.
How do you fix a Low Catalyst Effiency Bank 1 code P0420 on a 2001 Toyota Camry?
This code is generic and is the same on all vehicles. P0420 = Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should. This engine code can be triggered by any one of the following: 1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged. 2.) The secondary O2 sensor is malfunctioning. 3.) There is an exhaust leak. 4.) The computer unit is faulty
What is a PO420 code on a 1997 Toyota Camry and how do you fix it?
P0420 is the catalyst efficiency code. The most common thing is the catalytic converter itself is no longer functioning properly. The other likely thing is the rear oxygen sensor is no longer working properly.
What causes OBD code P0420?
This code means that your catalytic converter efficiency has dropped below the nominal value. p0420 is a generic code for the catalyst to indicate that you need to investigate a potential problem with your emissions system associated with the catalytic converter.Code P0420 means "Catalyst System Efficiency Below Threshold (Bank 1)"P0420 is actually Catalyst System Efficiency Below Threshold Catalyst System Efficiency Below Threshold.This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should.This engine code can be triggered by any one of the following:1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged.2.) The secondary O2 sensor is malfunctioning.3.) There is an exhaust leak.4.) The computer unit is faulty.Trouble code P0420 means: Catalyst Efficiency Below Normal (Bank 1)Code PO420 is catalytic converter efficiency low bank 1, sensor1. You did not state as to the year,make and model of the car as well as the engine size. I am a member of IATN and the majority of there fixes was related to someone installing an AFTER MARKET converter. There is a big difference. I strongly suggest that you go to a repair shop with the proper equipment as well as a very good tech to diagnosis the problem. You could replace parts and never fix the problem.jd1709
What does P0420 on a Lexus ES330 means?
P0420 = Catalyst System Efficiency Below Threshold Bank 1.Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic converter needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first.
What does enginecodes po420 po430mean dealer says conv needs replaced true.?
