CAT NOT READY-ON OBD2 READER

Today when I ran my obd reader I got a cat not ready, does that mean that cat is going bad? I had one side of cat replaced at dealer about a year or so ago, when I heard rattling. I don't hear any noise from cat...should I be afraid?

did you

read your codes like for a cel and erase them using the erase function?If so there is the problem it will set all the I/M monitors to not ready.It is part of the non constant emission monitoring system.Even if you had to take a smog test if you have no cel on, you can get by with 2 i/m status codes not ready,and eventually it will after enough proper drive cycles reset itself.
Or if you cleared the codes and need to take a smog test and i/m are not ready,follow----with common sense----
This generic OBDII drive cycle
Begin with a cold start (coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another). This condition can be achieved by allowing the vehicle to “sit” overnight, and then by beginning the drive cycle the next day. Most drive cycles will be difficult to follow exactly under normal driving conditions, so the driver should exercise caution, road safety, and courtesy to others.
* Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on.
* Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.
* Hold at a steady speed of 55 mph for three minutes.
* Decelerate (coast down) to 20 mph without braking or depressing the clutch.
* Accelerate back to 55 to 60 mph at ¾ throttle.
* Hold at a steady speed of 55 to 60 mph for five minutes.
* Decelerate (coast down) to a stop without braking.

As long as your other cat is okay,and it would let you know
no reason to be afraid

Every

Car maker has a drive cycle built into the cars ecu,tcu and other obd2 tied in systems.Some make it easy to find and others(guess who)make it near impossible so that if you clear a code say after cleaning a maf or replacing an o2 sensor the i/m monitors trigger a not ready,your cel is off but you will not be allowed to take a smog test.So they send you away and tell you to drive the car for several weeks and come back and your system is still not ready,you end up at the dealer with them telling you" next time allow us to repair your car because we are the only ones with our high price star machine that can reset the readiness codes"(secret code for get out your wallet and bendover).That's where I come in,figured there had to be a work around so after trial and error and a lot of fun blasting up and down a wide open stretch of hway with scanner hooked up I got it down to 15minutes,then after all that work We discovered the obd2 peeps were required to build in a generic cycle that should work on most cars,It is more involved then mine and not nearly as fun but it is safer and works and
That's the rest of the story.

how many miles on the car?

If

I anwser the questions before they get asked then i don't have so many in my inbox

I asked for miles cuz I saw you are less then 8years old and if under 80k you could have used the cat not ready status to push having the other cat replaced.If it does go just pick up one of the 50 buck oem cats and splice it in.

That's

what I do,my bookmark list is about 300 entries long of sites I must remember for when i need them.
Race Parts - Auto Parts - Car Parts - The Internet Racepages - RacePages.Com
eastern cats oem cats for most cars only 50 bucks and you just splice them in since the pipes are usually fine it is just the cat that goes if it fails so why spend 500 or more to replace the whole unit.

out of warranty the dealers get like 1500 bucks or such nonsense for one side.
