This is common in the Nissan's could be the cam and crank sensor these go at around 70000 to 120000 should do both at once to be safe. that will fail an emissions test for sure. hope this helps

1983 Ford Ecoline 150 /6cyl. Failed smog/ Egr numbers were too high How can i fix this to pass smog


Other than testing the EGR valve, not many options. You really need a 4 gas analyzer to know what is coming out of the tailpipe. Otherwise you won't know if repairs have helped the problem.
When you say EGR numbers I'm not sure what you mean. Most of the time the test is for CO and HC gases, along with oxygen and Nox also in some areas. The EGR valve allows some exhaust gas to be recycled thru the engine and reburned. CO or HC could be high if the EGR system is not working.

93 Plymouth voyager failed smog with high NOX .I've replaced transducer and EGR . The EG R was used and works . No check eng lite on but did pull codes #34+43+55


Although I could not find those specific codes, the grouping centers on various faults to the oxygen sensor, which was my first guess when I read about the high NOX levels. My local Advance Auto stocks the Denso direct fit oxygen sensor (Part No. 234-4004) for the 3.3 liter V-6 for $50.

What is the specifications for the upstream form the CAT O2 sensor to test

Co levels too high


The most likely cause is a combination of two things. I suspect that your catalytic converter has become less effective over the years and should be replaced. Also, the oxygen sensor is responsible for trimming the fuel ratio, and high CO indicates that the engine is running rich. I would start by changing the oil as it may be contaminated now, then replacing the O2 sensor. Then replace the cat. if it still fails. The oxygen sensor could really just be considered maintenance at this age.

I took my daughters 1995 Nissan Altima for its two year smog inspection and it failed three times due to nox failure at levels around 1400. Back in march of 2009 I took it to a reputable shop and they...


Check the ports if there is any carbon,I doubt it,
but you got to look
I would make sure you don't have overheating issues
That is the cause of NOX (High Combustion Temp)
Check fuel pressure
Use synthetic oil in engine
Check PCV Hoses etc

97 CAVALIER (Z24) FAILED SMOG TEST


No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.

Failed smog 1993 honda del sol s 1.5


Make sure all your tuneup stuff is good, plugs,wires, air filter. If the O2 senser is old it can be Lazy. Make sure the oil is changed before going for test. Make sure its good and warmed up as well. Good luck

Failed Smog Test - 4 codes for 2001 Isuzu Rodeo


Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
