Replacing the alternator is not going to help with your emissions at all. If your NOx readings are too high, there is a good chance that your catalytic convertor has gone bad. My suggestion would be to take it to an exhaust shop for the catalytic convertor (they should also be able to let you know if it is bad). As far as your alternator replacement, you can take it to any repair shop (possibly the same one who does the exhaust work) and they should be able to assist you with replacing it. Hope this helps.

My Toyota echo did not pass smog high Nox what could be wrong?


Nox is created in the engine, and the hotter the engine the more Nox is created.Get your car to run as cool as you can,oil change.engine/rad flush,fresh coolant,tune it up etc.In addition a high nox number may be a sign that your catalytic converter needs to be replaced.The converter is where the nox gets neutralized. good luck

High nox fail smog test any remedies? 99


NOX is created when the internal combustion temperature gets to high.The egr system uses burnt exhaust gases to line to cylinder walls.The purpose of this is decrease internal combustion temperature therefore reducing the amount of NOX created.Would look to a possible egr malfunction usually they will trigger the check engine light but not always.The 4.3L has been known to have issues with carbon buil up in the egr and the egr pintle not open and closing properly.

Having a problem passing a smog test on 1996 Toyota 4Runner SR5 V


NOX is produced when cylinder temperatures exceed 2500 deg. The systems in place to reduce NOX are EGR and the catalytic converter.
If the number is only slightly higher than avg then I would suggest the EGR, make sure that any vacuum lines are attached and that the diaphragm moves freely, be sure not to damage the rubber inside the EGR.
Retake smog test, if numbers still out of range replace the cat.

02 kia fail smog high nox


if the engine computer says that you have a slow O2 sensor what it means is that the sensor does not react as quickly as it should and it needs to be replaced. nox is oxides of nitrogen, a product of too lean combustion which causes cylinder temps to go too high. it sounds like replacing O2 sensor will make it happy. engine computer is having a hard time controlling lean/ rich fuel mix because sensor is slow to register changes, needs to have response time in milliseconds or engine computer can't operate properly. O2 sensors do wear out, normal service item. hope that helps

Failed smog


We had to have the calatic converter replaced. We did this after doing an oil change, air filter change, and new spark plugs and still hadn't passed smog. After changing the calatic converter it passed smog with scores of 25.
