Heres the problem, these converters are not cheap but if do some research you will see that most aftermarket converter dont last long, maybe a year or two, the next thing is a bad o2 sensor can cause a false converter eff code, have some one test the o2 sensors, a matter of fact if you have close to or over 100,000 miles it would be wise to replace them, theres three or four oxygen sensor or also called air fuel sensors for the front ones, a weak or slow o2 sensor will cause the new converter to go bad. i know its not cheap but something to keep in mind. it would be bad to have a costly converter to fail, anyway what im saying is make sure to get a good converter, we at ours shop learned the hard way, install good aftermarket converter and half of them came back with check engine lights, then we replace them and 6 to 10 months later there back again, this time we went to dealer but we had to pay for that converter which was alomost double the price and were stuck with the aftermarket cats there warranty was out and they wouldnt refund just replace the one that were under warranty and that didnt help as we knew the converter werent strong enough, do your home work on this, must get a nissan or good aftermarket, if you go aftermarket call and ask them about problems with nissan aftermarket converters and what there warranty. we had a few that a company was trying to tell us the car wasnt running good and thats why the converter didnt last, funny thing the nissan only had 40,000 miles and ran like a top and the owner was 76 years old but they tryed not to cover it, good day.

I scanned my car but got no codes. Catalyst mon INC, H/D Catalyst n/A, sec air system N/A, Oxygen sens mon INC, Oxygen sens HTR INC, ERG/VVT sys mon INC. any help would be appreciated. thanks

INC means the self tests that the ODB system runs are incomplete. N/A means those systems are not tested on your vehicle. If all codes are reset/cleared, or if the battery has been disconnected, the computer will run all the diagnostic tests to establish that the systems are working properly. In most states, most of these tests must be completed with no trouble codes detected before passing inspection. You will have to run the car through a number of 'drive cycles' to get all the tests completed.

Check enging light on 2003 Acura TLS doesn't come on when starting car. Failed emmision test because of it.

There is a problem with your OBDII (Onboard Diagnostics -2) system. The only way to find out why your Check Engine light is on is to scan your engine computer and find out which part of the system is failing. There will be fault codes stored in the computer to tell you. The failing system will then need to be diagnosed to locate the actual cause of the failure. Once this is completed, the computer will have to be reset, and the car will have to be driven (sometimes for several days) to get all of the computer monitors to run and recheck the system. If the repairs are successful, the same codes should not return. You may have new codes show up however. This is because some of the monitors are unable to run if the check engine light is on due to another failure. Sometimes a code like "Catalyst Efficiency Below Threshold" will show up when they were not there before. This is because driving the vehicle with the Check Engine light on has destroyed the catalytic converters, but the code could not set previously because the catalyst monitor could not run to test the catalyst when the other problem was present. Now that the first problem has been corrected, the catalyst monitor now runs and has determined that the catalyst has been damaged.

This why I tell all my customers that the best time to get your car ready for an emissions test, is the minute the Check Engine light comes on. Ignoring this light and driving the vehicle with it on can damage some pretty expensive parts, as well as possibly costing you fines for not getting your vehicle "Legal" when it is time to renew licenses, etc. I live in Missouri, and you cannot renew your license plates without passing the emissions test - people wait until the last day to renew their registration and they get angry with me when I tell them it is going to take several days and possibly even a couple weeks to get their car to pass. It's not MY fault!!! THEY are the ones who chose to ignore the warning lamp!

Need to pass emissions test, dianostic test - Catalyst efficiency blow threshold (bank 1) tried to order part - now I need to know if it pre or post, left or right Oxygen sensor, can it be determined by...

Yes it can be determined by the DTC (Data Trouble code). If the DTC is P0420 (catalyst system efficiency below threshold Bank-1) then the side of the engine with the #1 spark plug and cylinder is always Bank-1, and the O2 sensor that monitors the catalyst efficiency is usually after or (post) of the catalytic converter.

The #1 cylinder is located at the front spark plug on the right or the passenger side of the vehicle, so Bank-1 is on the right side of the vehicle, and the O2 sensor that monitors the catalyst efficiency should be located after or (post) of the catalytic converter. It would be the post right O2 sensor.

There is also the possibility that the catalytic converter is actually starting to fail, and if changing the O2 sensor and clearing the DTC does not solve the problem them the catalytic converter is most likely faulty.

Check System Light ON

this message is displayed to let you know that the catalyst is not performing to standards as outlined by manufacturer. this can be caused by the precious metals in the catalytic converter breaking down due to a possible lean condition or overfueling. this can also be caused by normal wear and tear too. hope this info helps!!

Main catalyst efficiency below threshold bank 2 cherokee 2001

If the readings were close to passing, use 3oz of acetone per 10 gals of fuel and it should pass. Then you have a whole year to figure out what's wrong with it! Main cat is the large one. all others are pre-cats.
