You should be able to take this to any mechanic you so chose if the code is right tell them and this is what it means
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 not so great.

2001 Toyota Sienna CEL displayed code P1150 & P0420 what could be the problem


Mine is a 2001 Sienna LE. I got the P0420 code and the dealer want to replace an engine control computer for $1600. I've found posts that say you can replace your oxygen sensors, which still costs around $100 each. The P0420 seems to be emissions related. When my check engine light comes on, I run the highest grade, no ethanol gas, and usually within a couple of tanks, the light goes off again. The last time it happened about 2 wks ago, I put in the 93 octane no ethanol premium and a can of Seafoam and within a half a tank, the light went out. Your problem might be more serious, and I don't know what the 1150 code is, but so far that's worked for me.

Cod p0420


P0420 is a catalytic converter inefficiency code. Basically the cars computer is looking at the rear O2 sensor to monitor the catalytic converters ability to properly reduce emissions. If the computer sees the rear O2 sensor acting differently than normal it interprets this as the cat no longer able to do its job and turns on the check engine light to make you aware there is an issue. There are a few things that can cause this to happen. The most common is that the catalytic converter has gone bad and needs to be replaced. The good news is the federal emissions warranty on these is typically 8 years or 80,000 miles. Sometimes longer if the manufacturer chooses. If you fall into this guideline call you local dealer and see if you are covered. If you are you will be able to have this replaced at no charge. The bad news is if you are not covered than you will have to pay for it out of your pocket and they are not necessarily cheap. Do not go with anything but either the o.e. cat or a direct fit from a put able supplier. Anything other than these two options will leave you with more problems than they solve. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

05' Dodge RAM 1500 code p0420. I've been changing oxygen sensors since u bought it 2 years ago, thought the problem was solved but yet again check engine light came on, could there be an other problem??


Hello: Code P0 420 indicates the catalytic converter is operating below calibrated efficiency (below 60%) replacing the oxygen sensors will not correct the condition. The converter needs to be replaced and the code cleared.

Engine light codes 02-3151 and P0420


Code P0420 is a code for Catalyst efficiency. The computer is seeing the post Catalytic converter o2 sensor having too much activity. The Cat. should be cleaning the exaust of Hc, co, and Nox. The post cat o2 will read the o2 content in the exhaust and if it moves up and down too much or to high and low, the computer interperates that as the cat not ridding the exhaust of it's pollutants. This indicates that the converter is unable to preform properly. The problem could be a bad cat, o2 sensor (Pre- and/or post cat)or o2 sensor wires, or an air fuel mixture problem that has caused the cat to fail. Many other engine operating system failures can cause the converter to not work properly.
