SOURCE: Test no pass

Have you got all your hoses running to the emmission control box (usually a round or rectangular box on the passenger side near firewall). Is the box old and needs replaceing? If you don't want to change because is very dear to do you could change your spark plugs and fuel filters? Also change your oil with a lighter oil a 55w/10 and oil filter and your spark plug leads with new ones 8mm diamiter would be good as it is less resistance for the spark which will aid in fuel burn and air filter change is good idea to, maybe 200 dollars or so to do this but all will help reduce your emmissions if emmission box isn't working properly. Hope this helps

If the SES light is on, take a paper clip bend it in a u-shape and jump the scanner input positions A B. This should flash the ses in sequesces to give you the trouble code, Please see the following link. http://www.troublecodes.net/GM/ Refer to the code to see what the issue may be. SES lit means that there is a emmissions related issue. Refer to the other links for additonal information on O2 sensor resistance, and the egr valve solinoid. Check the EGR is relitive easy for operation. Remove the vaccum hose and place a hose of similar suckon the hose to pull vaccum if the diafram underneith retracts, hold the vaccum by plugging off the tube with your touge if the diafram retracts, will not hold the vaccum, it is bad. The solinoid should read 40-60 ohms if good. http://www.saturnfans.com/forums/index.php http://www.aldlcable.com/sc/pages.asp?pageid=21

SOURCE: volvo 850 wagon failed NOx emissions test - badly!

Hey Pitloops!
It seems likely that one or both of your o2 sensors are acting up, or that your engine is sucking in unaccounted air from a leaking vacuum tube. Spray the tubes with "start gas" while the engine is idleing. If you hear it revving up when you spray the gas on the tubes you'll know there's a leak.
I'll sacrifice a squirrel for you and hope that the problem isn't your o2 sensors since they can be expensive to replace. Fcpgroton.com is probably the cheapest part supplier online if you'll need new sensors.
You might also want to clean your throttle body, as it usually gunks up with carbon deposits and sludge over the years. It only costs you the price of the carb cleaner to do it and the car will probably run better afterwards even if it doesn't solve the problem.
Good luck!

SOURCE: FAILED EMISSIONS

possible but could be head gasket or valves , or worn rings and is by passing the pistons going straight out the end ...or maby settings are wrong ? try carb cleaner and inspect visually air-filter etc.

Fail smog test


fist i would like you to post the year make and model of the truck along with the HC ppms and NOX ppm it would be very helpful but high hc and nox can be attributed to a faulty EGR system nox is produced when the combustion chamber temperature gets too high so a small amount of exhaust is cycled back into the air stream to help cool them there are other causes but without looking at the levels its much harder to say

NOxGPM reading was 1,8009. What does that mean and how can I fix this?


This means the nox readings are to high , this car is listed as a 1998 Altima is this correct? if so why are they testing for nox?

High nox readings can be due to engine running hotter than normal or egr system not operating .

Since your cat was replaced you should be looking at fuel problems...even gas cap seal....check fuel pressure,fuel regulator,and evap system.>canister or purge solinoid,o2 senser...high nox is caused by the cat or fuel problems on these engines...high pressure in the combustion chamber...lean condition>air leak on hoses,or high compression caused by carbon build up ...there is no EGR on this car so don't waste time looking for it...hope this points you to your problem

Lots of carbon in the cylinders,EGR valve not working,a dirty or leaking fuel injector,to far advanced timing.

Run 2 cans of fuel injector in 1/2 tank of gas and run it as low as you can before refueling.

I would set the timing back 5 degrees and test again,put it into service mode (check engine light on) if you have to to get timing back to cool combustion for the test.

This should lower the no% and the co% may just pass too.

Do not use premium fuel ( which is just slower burning fuel) when doing etests,or for normal driving if your engine does not require it,
It will cause carbon deposits in the combustion chamber and it will almost always give higher readings when etesting.

1998 Nissan Altima GXE squealing noise


Could be the bearings in your alternator have gone dry and your alternator is about to quit out on you. I had a friend with an 01 altima and we could always hear him coming before we saw him because of this very problem. Changed the alternator out and noise went away. Thanks for using FixYa!
