What does code dtc3 fail mean on my emissions test,,97 nissan pathfinder

Get the suspension springs checked. Park the vehicle on a flat, level surface with no-one in it. Stand back and carefully look at the vehicle. Sometimes when a spring fails the vehicle will lean towards the broken side. The tail ends of the spring can break off when they are old and the broken bits don't always fall out when it happens.
The stall could be something separate. Do you have any warning lights on the dash? If the charcoal canister is starting to fail it often causes the check engine light to turn on as it will affect the emissions. This will trigger other engine sensors to flag up a trouble code.

This is what it means:

Evaporative emission (EVAP) canister purge system - vent control valve malfunction

You can see it at this website and basically what the causes could be.

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 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 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 2007 Pontiac gxp I failed emission the two codes were dtc3 and dtc4

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.
  

P0455 NISSAN - EVAPorative Emissions Control System Gross Leak Detected. Possible causes - Missing or loose fuel cap (most common)
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking (not common)

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.
