Came across this procedure. Apparently it worked for them. Just coincidence, or is it legit? -------------------------------------------------------------------------------------------------------------------------------------- If the code was a po420 for insufficient catylitic converter efficiency you have a shot for a easy quick fix.As long as the guts are not rattling you will save a few bucks. Chances are they wanted to replace the air/fuel ratio sensors as well with that job.If its a cali car they are not 02 sensors.They are air/fuel ratio sensors.Now for the service.This is so sim

1940s, were first installed on California-market cars for the 1975 model year. By the late '80s they p0420 ford were universal on gasoline-powered light vehicles across the US and Canada. However, also by the late '80s, a problem had surfaced: Although the EPA had decreed that factory-installed catalytic http://www.odyclub.com/forums/9-problems-concerns/48441-po420-code-fix.html converters must operate in an approved manner for a specified duty cycle (currently 8 years or 80,000 miles), there was no way of knowing whether any particular cat on any particular car was actually doing what it should do, day in and day out. Federal law only dealt with what was required to be installed on a new http://tegger.com/hondafaq/p0420/index.html car, and not with what happened afterwards, that being a state matter. Not all states have emissions testing, so cars could theoretically go forever with a non-functioning cat. Plus, engine computers and controls of the time had no idea what the cat was doing with the gases sent to it by the engine; emissions control stopped at the oxygen sensor, mounted BEFORE the cat (the "primary" sensor). The answer was to revise the engine's computer to contain an on-board emissions-testing apparatus that would subject the catalytic converter to regular testing and monitoring as an unobtrusive part of the vehicle's normal daily use. This and other extensive revisions eventually culminated in what became known as OBD-II, which has been mandated on all new cars since the 1996 model year (but present on most or all V6 models for '95). Catalytic converter monitoring was achieved through the simple expedient of mounting an oxygen sensor AFTER the cat. In a nutshell, the after-cat ("secondary") sensor should, given a properly functioning cat, send basically a "flatline" sign
Repair Difficulty Level:2/3 | Add Comment http://www.autocodes.com/p0420_honda.html Forum Code Possible causes - Three way catalyst converter Bank 1- Exhaust tube- Intake air leaks- Fuel injectors may be faulty- Fuel injector leaks- Spark plugs may http://www.autocodes.com/p0420_honda.html be faulty- Improper ignition timing- Engine Control Module (ECM) What does this mean? 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). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is honda odyssey combined with other codes, try fixing the other codes first. What does this mean? When is the code detected?- Three way catalytic converter Bank 1 does not operate properly.- Three way catalyst converter Bank 1 does not have enough oxygen storage capacity. Possible symptoms- Engine Light ON (or Service Engine Soon Warning Light) P0420 Honda Description The Engine Control Module (ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 p0420 honda odyssey (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. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase.When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed.
