Has a green cap on it

OBD Codes for a sensor doesn't mean the sensor is bad,

All sensors have to be component tested first

Where? and how do you replace the purge valve on a 1998 nissan maxiam

The 98 model uses a square canister located under the left rear quarter panel.
There is a canister purge control valve and a canister volume control valve, so make sure you are dealing with the right valve.
The volume control valve should be on or near the intake manifold, and the purge control valve should be near the canister.

P1443 code problem. How do I fix this?

P1446 - EVAP Canister Vent Control Valve Close
EVAP canister vent control valve remains closed under specified driving conditions.

This solenoid valve responds to signals from the ECM. When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.

This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP Control System (Small Leak) diagnosis.

The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.

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

About the possible causes that your must solved:
- EVAP control system pressure sensor and the circuit
- Blocked rubber tube to EVAP canister vent control valve
- EVAP canister vent control valve
- Water separator
- EVAP canister is saturated with water

Hope this helps.

Ford escort wagon 1997 code p1443 displayed. what does this indicate & where is the cannister? thank you.

P1443 - EVAP Control System / Vacuum System Purge Control Solenoid Or Purge Control Valve Fault. A fuel tank pressure change greater than minus (-) 7 inches of water in 30 seconds occurred with a purge (fuel vapor) flow at less than 0.02 pounds per minute.

Possible Causes:
  • Blocked fuel vapor hose between the EVAP canister purge valve and the FTP sensor.
  • Blocked fuel vapor hose between the EVAP canister purge valve and the engine intake manifold.
  • Blocked vacuum hose between the EVAP canister purge valve solenoid and the engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).

  • Possible Solution:
    Check for blockages between the fuel tank, the EVAP canister purge valve, and the engine intake manifold. Check for obstructions in the EVAP canister purge valve diaphragm and ports.

    The canister is on the passengers side near the firewall if I recall correctly.

    Starts up but will not stay idling, bad gas smell comes out of it.

    Hello! The gas vapor system, which is under pressure, must be purged...Without the ability to purge fuel will not flow...This is the reason the engine will not idle...Because you smell gas vapors is an indication the vapor canis ter purge valve is either defective or has an open/broken vacuum line...Follow the vacuum diagram under the hood and trace all lines..."tired" vacuum lines will **** closed, replace any cracked, broken or soft lines...If this does not solve the problem replace the purge valve...See picture

    Check Engine Light

    Ok i have the same make and model car.And had same problem but i was only needing new hoses. thwe code reader will not tell you if they are bad you just have to check this. The purge valve and canister is located under hood on passenger side behind bumper. look behind the light through the openings. You have to raise car up and do the repairs from under the bottom of the bumper.On passenger side under hood above the wheel fender and between the engine you will see a emmision line about the size of a pencil leads to the purge valve. the valve cost about $18.00 and canister cost around $75.00 at auto zone. The canister is the square box and sometimes you can take apart and clean it and put back together and it should work fine.
