SOURCE: CODES,P0442,P0455,P0456,P1684

P0442, P0455 AND P0456 are all evaporative leak monitor test failures (small, medium and large leaks). These codes appear anytime the integrity of the air space above the fuel or the lines to/from the vapor canister or purge valve. If there is no damage to the canister, check the lines that run under the van from the fuel tank and canister to the purge valve (under the hood). Also, check to make sure that the hoses are not split or disconnected where they connect to the purge valve. The P1684 is abit more confusing. This is not a valid DTC for your vehicle. It's possible the scanner the shop you went to is an OTC scanner that is reporting a false code. It's also possible they wrote it down incorrectly. The closest thing that makes any sense is a P1486 which would indicate a pinched hose in the same monitor system as the other 3 codes. Best of luck!

SOURCE: HCL too high, did not pass smog check.

ok well this might be a hard one . from what i can gather by the co reading and the o2 reading is that we are running fat. a couple things can cearte this one how many miles do we have on this mtr, two do we have a vacuumn leak? three is the vech going into closed loop? some how we need to get are hands on a scanner so we can look at a data, other wise you are going to be throwing parts at this vech , and thats not the way to fix your problem. the odds are that you may have some lazy o2 sensors you are close. have you tryed running the vech down the road before you go in for the test. the converter is like a hot water heater you have to bring it to operating temp before it will operate correctly. keep me informed

Won't pass smog when it should...


Just because the car seems to run well, does not mean the emissions are within spec. For example, you could be running a little rich and the car will start and run great, but the exhaust is not within code.
What you can do is take it to a "smog shop", that is a repair shop with the proper equipment to diagnose the problem. If the testing is simply the reading of the on board computer codes, then most any place can read those, but you need an experinced mech to know what to do about it. May need an exhaust gas analyzer to physically sample and analyse the gasses. For the actual test, as long as the computer says all is fine, usually, you're good to go.
If the computer looses power any saved run data will be lost and must be re-accumulated to pass the smog test. A few hours to a day is usually enough run time to accumulate enough data.

The shop is still responsible to reset the trouble codes! Bring it back with your receipt and after they reset it get the thing inspected...preferably at a different shop where they COMPLETE a job!

My 1999 kia sephia wont pass smog test


You will need to get it scanned and get the codes for the problem. If it failed the test due to emissions I would almost guarantee it will be your oxygen sensor or cat

Now car won't start, checked fuses all ok


P0455 will not cause a no start. P0455 is leak in the fuel vapor recovery system, it will never cause any type of drive related issue. Have the fuel pressure checked and see that you have spark, my bet is the fuel pump has gone out. A defective electric fuel pump will not set any code.

My 2007 Chevy Avalanche failed the emission test with the code of P0455 what is the problem?


It is probably the evap vent valve. A new vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I hope this helps.

My CE light is on. The code is PO420. It is a 2002 Corolla. Smog is due. Two years ago, the same thing happened. I bought a scanner, cleared the light. Took it to smog. Passed. But this year, I cleared...


The P0420 is for the catalyric converter, you'll have to have it replaced. It will fail the test as long as the light is on. Clearing the code information also clears the monitor infor, to pass the monitors required you'll have to put some miles on it in both city and highway driving, not all monitors may be required so check with your local smog station which ones have to pass.

Need list of fault codes for deawoo lanos 1999


Not a solution: This is my problem...
I needed to get my car smogged, but the check engine light was on. Took to to a local smog station that had replaced a sensor for me in the past in order to pass smog. They could not fix it. Put car in dealership garage for repairs and to date, the transmission module sensor (computer) went out and the ignition sensor was out also. The mechanic replaced both and now the code P1702 comes up. What does that code mean? My car still won't pass smog....

Code p0445 evap. emission control system leak,large


that means you are driving whit the fuel cap loose or missing or you have a vapor leak on the vapor lines coming from the fuel tank to the engine, have your car inspect for leaks, but make sure to ask your mechanic if he has the smog machine to aply smog to the evaporative system that,s the easiest way to fin a leak,
