Have to do emissions.
My car has a fault code It's for the malfunctioning heating element of the O2 sensor . The O2 sensor works fine. The heating element does not. It has no actual impact on emissions, but tosses a fault either way. The car runs great otherwise, and will pass the tailpipe portion of the test. I' being a cheap bastard and not replacing the O2 because it works fine except for the little heating cycle that the heating part does for 8 seconds on start up. Will I pass the emissions test when they scan my codes? This is part of the O2 sensor but not really an emission control. Or will I be buying a new sensor? Thanks! |

I am pretty sure if you have a check engine light period you fail

Clear the codes and drive it for 60 or so miles if the light dose not come back on, bring it right to the testing center. Any auto parts store will be able to clear them.

Passing the test all depends on how far the sensor stick goes into the tailpipe.
Sometimes they just put the tip in, and others they go all the way to the connector. |

I've put 15k on the car at least since it started occurring. Mileage is the same. Runs great. |

Obd 2 if you have codes it will list them on the report. Check engine light on you will fail
Obd 1 I passed with a check engine light sniff test

Are there any unethical emission stations left?
The one ethical thing Rowland did was to clean up the emissions scam of all fucking things.
I can trade the guys dinner pics or maybe some reduced capacity magazines |

You may want to have their test wand checked under a blacklight. Just to make sure its clean. Those things are in and out of tailpipes 8 hours a day 5 days a week.
Lord only know what is on there. |

Rockauto.com buy a new o2 sensor and I can replace it for you. You will fail if your check engine is on. If I remember correctly its a grey car right?
Eta: is it the primary or secondary causing issues? |

I don't remember exactly. I checked when the code first tossed, but then just forgot about it once is figured out that there was no impact to the actual function of the O2 operation. Can a vatozone scan it and tell me which? Will the TPS sensor cause me to fail too? I think it's just corroded |

As long as your tps isn't throwing a code you should be fine, it could cause bigger problems down the road though. Erratic idle, serious hesitation, etc, etc.

I've had a code on for around 20k miles the past year and a half and now I'm due for testing as well. Mine is throwing camshaft position sensor, and both are bad. Clear codes with a Gensys and they come right back.
Between the check engine light, the ABS warning light, being stuck in FWD (another light), and my low fuel light it's almost like a Christmas tree on my dashboard. |

Also throws off my vehicle skid fault, but that's pretty useless too. I just would turn that noise off in the past anytime the weather was bad anyways. |

Any autozone can run it. I think your fine with the TPMS. You get a 30 day grace period to fix anything if you do fail. I know it's a PITA to go back.

That is correct, but if you have a true problem the CEL will just reappear. Neg terminal for 15 minutes and leaving the key in the "on" position helps drain the ECU if any residual power.

^^ Works for major auto manufacturer as Quality Technical manager (Field Service Engineer). Been in the car service business for 30 years this June. So I do know a bit about this.
CT's emission testing program has two types of tests. 1. If your car is model year 1996 or newer it will have the OBD II system. This system is standardized for all manufacturers and mandates the parameters of the fault code and the fault codes are also standardized. If your car is 1996 or newer the test is simply to plug into the Data Link connecter and check the "readiness" status and for any faults. If readiness is not set or you have faults you will fail. Readiness is the automatic testing of certain on board emission controls by the vehicles ECM. These tests are mandated by the EPA and all cars have to pass them. 2. If you car is older than 1996 your car is pre OBD II. Some model year 1996 vehicles but were built before January 1, 1996 have OBD I. These vehicles are tested for tailpipe emissions. You will be hard pressed to pass this test without actually fixing your car. There are 2 readiness bits that relate to O2 sensors. One is for O2 sensor function and another for O2 sensor heating. Until these bits set you will not pass the emissions test. TPS=Throttle position sensor. TPMS=Tire Pressure monitoring sensor. TPMS warning light on should not trigger a failed emissions test. What kind of car do you drive? |

1995 or older gets a tail pipe test with the car spinning the wheels on the dyno.
You get 60 days to fix it if you fail and you are not late on your initial test Clearing the code wont help,you will fail for clearing the computer. fixing it,clearing the computer then driving it for about a 100 miles to set the readiness monitors are the only way to pass Nobody will take a bribe,10000 fine and very hard to pass a failing vehicle The tail pipe probe gets flushed with zero air before and after each test so no failing residue is in the probe |

CT emissions is such a joke. Some years back I had an OBD II hopped up tuner turbo car. Well I was running way bigger injectors so I was running a piggy back fuel management system to control the fuel. The system itself caused a check engine light. I obviously couldn't pass so I unhooked the fuel management system and the car barely ran. The emission place was literally I mile down the road and I wasn't sure if I would even make it there. Car was spitting fuel out of the tail pipe as I pull into the emissions place. Since I cleared the CEL I passed no problem. Got it home plugged everything back in and the CEL came right back on and the car was ready to rip again. Like I said its a joke.

my old Camaro with the tuned port passed the sniff test with a gutted cat about 10 years ago. I also took another Camaro with a tunnel ram and 1300 cfm worth of carbs to get tested. I ended up driving it on the dyno that time. it failed for co and hydro carbons but had zero nox emissions |

Had something similar happen with a Nissan sedan many years ago. There was a hole in the muffler and the car barely passed emissions two years in a row. Replaced the muffler after it fell off weeks before the next emissions test and the car promptly failed the emissions test.

It really depends on the tech.
I had a 96 VR6 suped to high hell years back. Check engine light on for cat under efficiency (cat was removed), I took it in for hahas - handed the tech my keys and turned around to go sit down. I barely had time to sit down and my name was called up. I went to the desk and they handed me my paperwork. Said I was gtg. Tech must have liked my car or something. I laughed, said ok, thanks, and left. Now I just brought my F-250 in last weekend and they said they couldn't administer the test because I didn't have a tailpipe to hook up. (Tailpipe rotted away and I yanked it off, but the rest of the exhaust is fine.) I said, "you can't just hook it up to the muffler, all you gotta do is bend over". The guy didn't think I was funny, and told me to get a tailpipe.  Got it, round two today.

I remember a few pucker sessions back on the turnpike riding shotgun in an old 80's VW that weighed nothing with a hot VR6 swap. Certainly not the fastest car, but with the lack of mass to tug around, it had a quality all of it's own. |

This thing had to hold the car on the rear left wheel's parking brake while about 330ftlbs tried to drag. The car's ass across the carpet like a dog with the shits. That took a creative "tune" to keep the power low enough not to overcome the brake's minimal holding power. (Added slack to Throttle cable and nearly choked off Intake and a second gear start) |

It is designed to hold the car and keep it from rolling when parked not to hold it in place when trying to drive. Yes it used the rear brake shoes but that lever could not develop anywhere near the pressure the hydraulics could. This is why we have hydraulic brakes not mechanical. |

Since 2008 we are a CA emissions state and as such the warranty for emissions is the same as California. However for penalties we follow the Federal emission guidelines. The warranty issue is a problem because dealers do not understand the laws. They think CA emissions warranty applies only to CA, it applies to all states that follow CA emission standards. The warranty is much inclusive of components. There is also a PZEV/ZEV emissions warranty that is 15yrs/150,000 miles and covers a ton of stuff. In my day job I have had to intervene in cases where the dealer is charging people for items covered because they do not pay attention or read. This being said almost never have a seen a car being flagged for emission law violations due to "tuning". |
