Code p1443 is a malfunction in the evap system. It can be a loose gas cap, a bad flow sensor/circuit, a bad evap solenoid/circuit or even a leak in the evap system. The evap system is designed to trap gas fumes escaping from your gas tank/fuel system contributing to pollution. So really your truck should still run alright, but it may even be your stupid gas cap.

Where is the purge control valve located on 1998 nissian pathfinder


Location should be back by the fuel tank.

first off, the P1447 DTC is triggered when the EVAP control system isn't operating properly or there is a leak between the intake manifold and the pressure sensor. the parts between the pressure sensor and intake manifold are:

1. EVAP canister purge control solenoid valve
2. EVAP canister purge control valve
3. EVAP canister purge volume control valve (Part # 14930-3M201) YOU WILL HAVE TO DOUBLE CHECK ON THE PART NUMBER WITH THE DEALER FOR THE PRICE.

If you've received this P1447 DTC, chances are that the brick of charcoal in the canister has fallen apart over time, and filled the lines with charcoal. this affects parts 2 & 3 from the above list, and of course the EVAP canister (Part # 14950-1s717 $144.22). but when you replace the canister, you have to replace the EVAP canister vent control valve (part # 14935-54u06 about $100), and don't forget the o-ring (part # 16618-40u00 about $1.60) that goes between the canister and the vent control valve.

If you attack this DTC early enough, all you have to replace is the canister and vent control valve with the o-ring, which will add up to under $300 MSRP...a lot better than paying upwards of $1000 for parts and labor. Don't be scared to do it, it's actually quite simple.

Computer code 455


Possible causes - Missing or loose fuel cap
- 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 The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

When is the code detected? EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors P0455 Buick Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.
if tightening the cap or replacing the cap does not help take your car to a shop to have it diagnosed as it requires special tools/equipment to test this and get an accurate results to find what needs replacing.

2002 Nissan Frontier showing a P01444 code


P1444 EVAP Canister Purge Volume Control Solenoid Valve
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor from the EVAP canister is regulated as the air flow changes.

What does code p1447 mean ...???


The code says "evap purge flow monitor fault"
Possible causes include ...
- EVAP canister purge volume control solenoid valve stuck closed.
- EVAP control system pressure sensor and its circuit.
- Loose, disconnected, or improper connection of rubber tube.
- Blocked rubber tube.
- Blocked or bent rubber tube to MAP/BARO switch solenoid valve.
- Cracked EVAP canister.
- EVAP canister purge volume control solenoid valve.
- Closed Throttle Position Switch.
- Improper connection of one-way valve.
- Blocked purge port.
- EVAP canister vent control valve.


This is a "jackpot" code. It points to so many possible causes as to be almost useless.

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.

Symptoms
- 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.
