I means that the vehicle failed it's emissions test as it failed the digital trouble code reading test 3
the testing station tests the exhaust emissions and the onboard computer
Your computer failed the test

How to fix the code p0410 in a 1997 Nissan Pathfinder

Code 410 is for a problem with the AIR system but I don't have the explanation for a Nissan.
The AIR system pumps cold air into the exhaust system to lower emissions.
You might try using a search engine to look for the test procedure for Nissan.

I have a 1999Nissan Pathfinder I can't pass my admission test why

I presume you meant to write emission test . There will be a certain type of emission that is too high. The test result will tell you which that is. But the first thing to do is have the computer scanned for trouble codes...and start fixing what the computer recognizes as a fault......
you will need expert help for this unless you buy yourself a scanner tool etc.

What is the drive cycle for a 2000 Nissan Pathfinder?

What is not ready?

One of the 8 Emission Monitors?

Drive cycles have to be looked up in factory manuals
& done by a repair shop, NOT the vehicle owner

Seldom do you need to do a drive cycle

If a drive cycle is done for a reason, there is no driving a vehicle
hundreds of miles, as you hear about

I would guess you have an Emissions Failure

Exhaust Converter
Oxygen Sensors
Cylinder Misfires
Egr Issue
Evap System

What ever codes you have, will tell you the system to component test

Need scan tool to look at data,thus a repair shop

I have a 1998 Nissan Maxima GLE, I Failed the Emission Inspection (DTC) Diagnostic Trouble Codes of "P1492","P1105" What these Codes exactly? mean

A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective compute
  • P1105MAP/BARO Pressure Switch Solenoid Valve
  • Check and clean the MAP sensor, or replace.
  • P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
  • Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.

I have a code P1447 Evap purge flow monitor on my 97 Pathfinder. What is and how do I correct this issue?

P1447 - Evaporative Emission (EVAP) Control System, Purge Flow Monitor
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions. Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP control system pressure sensor to intake manifold vacuum.

Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow are adequate. If not, a fault is determined. Malfunction is detected when EVAP control system does not operate properly, EVAP control system has a leak between intake manifold and EVAP control system pressure sensor.

- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
* EVAP canister purge volume control solenoid valve stuck closed
* EVAP control system pressure sensor and the circuit
* Loose, disconnected or improper connection of rubber tube
* Blocked rubber tube
* Cracked EVAP canister
* EVAP canister purge volume control solenoid valve circuit
* Closed throttle position switch
* Blocked purge port
* Closed throttle position switch

Test is and send us your updated.

1997 Nissan Pathfinder 153,000 miles service engine light on catelytic code runs great, just had new tailpipe & muffler installed. I'm told fixing this code could cost $1,000- 2,0000 is it...

If you work on your own vehicle, it would be $324.00 to $429.00 for the converter,at NAPA,if you even need one.
Unless you fail inspection for emissions, I would just have the codes read for free,write them down,look them up,then forget it, until I fail inspection a year from now.
That said,if the converter is blocked and causing you to loss power,then you replace it.
It is a bolt on item,check it out on NAPA web site.
Can not cost more than $80.00, plus part, to just bolt on. Have a relative do it in the driveway.

I failed the emisson's test. I have a 97 Nissan

P0136 indicates a bad O2 sensor. This reports poor emission performance back to the car's PCM (computer)
P0325 indicates a bad "Knock" sensor which would adversely effect drivability as far as performance is concerned. Only way to fix these 2 problems is replacement of the 2 components.
