emissions.......booo!!

[truckin151]

When you crank the key to the ACC position and your MIL blinks a few times and then fully illuminates steady it means your OBD monitors are in a readiness sate. If it continues to blink then its a indication that its not ready.

Right now when I turn the key to the ACC position the MIL stays solid, does not blink at all.

You said that it was o2 and egr not ready. You have EGR and it's not deleted. If it's faulty will it show not ready? What if I delete the EGR? I think 1/2 the folks out there have deleted their EGR and it passes emissions. I wonder if deleting that system will do it?

Is ur truck getting up to temp? Sometimes it'll not go into readiness if the temp isn't high enough

Its getting up to temp, It hits 188 normal driving and 206 stopped in traffic. When I rolled into emissions yesterday it was right between 190*-203*.

There are no error codes so if the EGR or the rear O2's were bad its not indicating that it is. 2 years ago, I believe it was right before the cam install, was when I had it run through last, so really the only thing that has changed was the cam and tune. But we have ruled out that the tune was not turning off the egr or the O2's.

Only thing I can think of is back in May I jumped my brother-in-laws mini van, since then I have driven the truck but not hundreds of miles just short trips here and there. So maybe that is it. I dont really want to mess with the tune if it does in fact take a week of driving (150+ miles) because I will basically be starting over and it is due on Saturday.

Can Autozone or one of them test readiness monitors WITHOUT reseting them? Or better yet, can the DSP datalog show the not ready state?

Most OBDII Scan Tools can run a i/m readiness test so no harm in checking Autozone. Torque App has the option but not to about DSP, SCT or SC.

Even though i am emissions exempted (zip code) i wanted to drive the truck more into the office which meant i needed to go through emissions. Heard they allow up to 2 monitors out of 8 to be "not ready" before fail. I had Sean disable my EGR but kept the rear o2's ready since non foulers do the trick. A/C sensors codes removed themselves and i am completely MIL free which is the first thing they check before going doing the OBD check.

Passed 1st try but was i nervous in case they also decide to do a visual since EGR and Cats are required for my VIN.

Is it possible to find which exactly which monitors are not ready since there are around 8-12 depending on vehicle?


Sucks man.

My mistake. I checked the manual which is different to what i said.
This is from my 2004 PDF Manual

Our mv has the stuff to do obd II testing but still uses the sniffer thing. Ran mine through middle of last month. passed first time, was worried cuz of my intake setup and exhaust. they smacked my pee pee about the damn bulbs for the amber strips though...... Stupid head light....

Alright checked it out, with the key in the acc position after about 20sec the mil starts flashing. Can someone please check and confirm this with theirs.

Mine remained steady illuminated. Went away when i started her up a minute later.
Checked torque app

What is needed with the tq AP?

Bluetooth Dongle. Just got a cheap one off Amazon Amazon.com: BAFX Products (TM) - ELM 327 Bluetooth OBD2 scan tool - For check engine light and other diagnostics - Android compatible: Car Electronics

PID Refresh rate is not as good as cable and takes forever to read/scan codes but for the price its a very nice app/tool to have.

Well 300 miles down, mixed driving city/hwy, cel still flashes doing the key on check. Going to take it down tomorrow to have it checked

be sure to fill the fuel tank the night before.

SmokedRam it worked thanks so much!

A Drive Cycle replicates the conditions of a person going out and driving his vehicle after it has been sitting overnight. First, he cold starts his engine and it warms up a bit while he is buckling his seat belt, selecting the radio station or CD he wants and adjusting the volume, and letting the windows defrost a little. The car is then driven through stop and go scenarios through city streets at speeds of 25 to 35 mph. Then, the car enters the freeway and accelerates briskly at half throttle or more to match the speed of the other drivers as the they enter the flow of the freeway traffic. Then the vehicle is driven at a steady, conservative speed of between 55 and 60 mph for at least four to five miles.

After this, the vehicle pulls off the freeway and is driven a bit more in city driving conditions before pulling into a parking place where the engine idles for 20 to 30 seconds before being turned off. On many vehicles, one of these Drive Cycles is sufficient enough to set all or most of the Readiness Monitors. Other vehicles require that this entire process be repeated on two or more successive days.
