OBD-2.. how long does it take for sensors to cycle??

[jaidedeye]

my OBD-2 test is due this month...after clearing the computer, how long does it take for all sensors to run thier cycle??????

i cleared my computer like 2 weeks ago almost and i still have 3 sensors not complete...WTF?????

about an hour or two driving it. I think mine was like 50-60 miles or so. Just an educated guess.

you have to look up the drive cycle. probably you hvae to take it on the highway for about 100 miles, then have your tank go down to 1/4. also you have to do a lot of accel and decel.

thats assuming that the 3 moniters that havent run are EVAP, EGR and catalyst efficiency.

YEP THOSE ARE THE 3 MONITORS THAT ARENT DONE YET......HOW DID YOU KNOW??

 

[bdcardinal]

those are the most commonly unrun moniters.

what mods do you have?

 

[jaidedeye]

off road x-pipe with mil eliminators, bbk headers, mac cold air intake, all forged manley pistons, h beam rods, cobra crank, mac cold CAI, undrdrive pulleys, 80mm c&l mass air meter, 24lb injectors........th rest of my mods are all in the suspension........the engine has 15,000 miles on it.

so why are those test so common not to not finish testing? i cant get my inspection until those finish.....this is wierd.....

do i have to have all of the cycles complete on all of them to pass????

emissions is new in my county so nobody really can give me any straight answers,

 

[bdcardinal]

i dont think the MILs allow the cycle to complete, you probably should switch back to the stock H pipe.

have you modified the EGR system at all?

for the evap code, you have to have your gas tank between 3/4 and 1/4 full for it to set.

 

[jaidedeye]

theres other guys that pass with mil eliminators......HMMMMM

well i have like a full tank of gas right now......

the egr has never been tampered with and has never thrown a code.....

is it true that the epa allows 2 monitors testing to not be complete?

 

[bdcardinal]

its different for every state on how many moniters are allowed to be incomplete.

the easiest way to pass is to put on the stock H pipe.

[jaidedeye]

thanks man...have you used it before?

i would have figured that even after two weeks of driving all the monitors would be good.....hmmmm

Right now im going thru the same problem. But everytime i hop on the freeway and drive for lil while i trigger my engine light. Its the stupid p1443 code

You gotta drive for lil while cause the smog machine can detect that you reset the codes and will fail you.

 

[jaidedeye]

well im not throwing any codes...no check engine light either.....

just the p1000..thats it...
