Hi there

There are a few ways you can do this:

Use ultra-low sulphur fuel (not sure if the US has this but the UK does).

Change or clean out the air filter (check my profile for a how-to)

Make sure the EGR valve is connected up properly. This is the exhaust gas recirculating valve, located on the intake manifold. Unbolt is, clean it out with a wire brush and carb cleaner, refit.

Get the Nissan checked again, if it is still high, the catalytic converter could be due a change, especially as it will be 12 years old.

Hope this helps, please vote if so. Thanks :)

Pass smog test


change your oil and oil filter. Add a bottle of octane boost to the fuel tank then top off with fuel. Drive vehicle for about twenty minutes then have emissions tested. Unless you have a bad catalytic converter, you should pass emissions.

My nissan altima 1999 did not pass the smog test due to "high emission", it also does not have the check engine light on or give any obd codes. What could be the problem?


Robert, High emissions usually mean the EGR valve and several hoses and other smog components are clogged up. There is no easy fix, you have to get the shop to check through the smog system on your car if you cannot do it yourself. Type of driving, short runs, high miles, burning oil etc all contribute to the engine giving a dirty reading. It may not be enough to light the lamp but it'll be dirty enough. Of cause, it may be the lamp is bust as well? Does it test light when you start up?

My 85 nissan pick up wont pass smog cause pollution number is to high. could it be vacuum hose leak?


Where do you live? Some locations (states/provinces, counties/parishes, and cities provide a waiver for vehicles older than 25 years. Check out your area's regulations. You may be able to avoid the emissions test completely. Good luck.

1986 NISSAN 300ZX FAILED EMISSIONS HIGH CO


I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !

WONT SMOG


wrong arrangement of piston rings affects intire performance of an engine. and must see that.
have you calibrate your injection pump? and change your injectors?
have a shop with scan-tool diagnose the problem.

High Emissions output


did you fail a smog test? if you did... i always pass smog because i always have a new catalytic converter installed .if i was a little over the test, this usually gets me down a little lower and that's passing!

P0440, Nissan quest


the most common cause of this in Nissan is a defective carbon cannister vapor purge valve in the evaporative emission control system.

SMOG TEST


If it was originally intended for Texas, it's probably been made as a 49-state-compliant vehicle (CA has stricter emissions). To pass in CA, you may need some new parts for the truck in order to get it to pass. Or you may find that the best course of action is to sell the truck and buy a CA-emissions car.

The CA DMV may well have information available on how to get non-CA-compliant cars to pass the CA emissions testing.
