Default 0420 Code for 2002 Camry LE V6

My check engine light came on and the code was 0420. The car runs fine and
aside from the light, I don't feel anything is wrong. I had the mechanic
turn the light off.

Any thoughts on what it could be? Something to do with 02 Sensor/Cat on
Bank 1 I believe.

P0420 Catalyst System Efficiency Below Threshold (Bank 1)


Try this link,
http://autorepair.about.com/cs/troub...l_obd_main.htm, or use
your favorite search engine to look for "OBD II Codes".


I don't know what can make the efficiency be below the threshold, but my
first guess would be the sensor itself. The CAT can be toast, but I would
not expect it to be bad at this point in your car's life. This is an
emmission system item, and should be covered by the warranty.

what are the symptoms of a bad cat convertor or oxygen sensor? I passed my
drive clean emission by a WIDE margin 2 weeks ago. The dealer said I need a
firmware upgrade for the CPU

Cat is degrade by 60% or better. It will come back on

Your car is a 2002, so you will find the OBD II data port along the
underside of the dashboard, in the vicinity of where your left leg is while
driving. The port looks sorta like a printer port (on the printer, not on
the computer), except it only has something like 16 pins instead of the
printer's 40 pins. The shape of the pins and the connector look like the
back of a printer, but there aren't as many pins.

Anyway, many auto parts stores have the OBD II code reader in stock, and you
can check it out - like a book from the library. Use the code reader to
reset all of the codes, then don't worry unless the Check light comes back
on AND it throws another P0420.

It is conceivable that you would need a firmware upgrade, but if the logic
is that the computer is an emission system component, then the firmware
should be a free upgrade during the emission system warranty period. For the
firmware to be the problem, then there is nothing wrong with the car, but
the check for whatever this sensor is telling you has a window tha tis too
small, and the firmware will make the window larger to prevent false
reporting of this particular error. If you reset the light, then the odds
are that it will not come on again for a very long time, and this would tend
to point to firmware errors causing a false report.

Thanks Jeff.

I went to the local garage and his brother works at the dealership and told
me that since the car is running fine, the computer needs a firmware update.

I had the light reset and so far, it has not come on yet. If it does, and
as you said, I get the same 0420 code, then I will get the firmware upgraded
to the cost of $100. Since the car now has about 70,000 miles on it, it is
out of warranty and this is a "grey" area under the ECP Toyota warranty.

So far, I have had the Check Engine light come on 2 times : Shift Solonoid
Malfunction, and when the Throttle Body was frozen. Both times it was fixed
in warranty and under ECP and the repair bills were $2400 and $1500
respectively.

Needless to say, when that light comes on, I think "oh crap, there goes
$1K!"

Your Emissions System Warranty runs for miles or time, WHICHEVER TAKES
LONGER. You are nowhere near the time, and the firmware upgrade should be
free. Stomp your feet and get red in the face and demand that the emissions
system is malfunctioning and should be repaired - whatever it takes - under
the warranty that is there specifically to protect you from this sort of
failure.

The whole point of the warranty is that the consumer is open to huge repair
bills from a federally mandated system that is by its very nature prone to a
hostile operating environment. The manufacturers are required to make the
system withstand the hostility, and yours seems to be prone to problems that
can be corrected by a simple firmware upgrade. It takes a matter of a few
minutes to load new firmware, and the alternative for the dealership is to
fix hardware so it complies with the small window tha tthe firmware demands.
They (apparently) found that there was a significant number of repairs to
whatever the P0420 reports, and the timing window was too small. The way
they figure this out is by taking the stuff back that is repaired under
warranty and then testing it. The sensor that reports the P0420 errors could
have been found to be within spec, but the ECM is still reporting the error.
The fix is to open the window for which the sensor can come up to speed, so
to speak.

In any case, just because you have gone over the waranty period - in miles -
for the rest of the car, you have not gone over the waranty period - in
time - for the emissions system.

Jeff: Looking in my 2003 Corolla Owner's Warranty book (Federal Emission
Control Warranty), let me quote the following:

"Federal regulations require that this warranty be in effect for two years
or 24,000 miles fro the vehicle's in-service date, whichever occurs FIRST.

"Additionally, components marked "8/80" in the parts list on pages 15-16
have coverage of eight years or 80,000 miles, whichever occurs FIRST.

Thanks for the education. The last time I had to get warranty service on my
emissions system, it was the longer of the two. I was not aware that this
had changed. I do have a new Tacoma though, and I'll have to double check
just beacuse I'm a "doubting Thomas" kind of guy.
