DTC P0497: Evaporative Emission (EVAP) System No Flow During Purge
Circuit/System Description
The control module tests the evaporative emission (EVAP) system for a large leak, or a stuck closed EVAP canister purge valve. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge valve OPEN and the EVAP vent valve CLOSED. This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or the vacuum level increases too slowly, a DTC sets.

Diagnostic Aids
• A loose, missing, or damaged fuel fill cap can cause this DTC to set.
• A stuck closed, blocked, or restricted EVAP canister purge solenoid valve, can cause this DTC to set.
• A blockage or restriction in the EVAP canister purge solenoid valve vacuum supply hose, EVAP canister purge solenoid valve purge pipe, EVAP canister, or vapor pipe, can cause this DTC to set.
• A temporary blockage in the EVAP canister purge solenoid valve, purge pipe or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system.
• To help locate intermittent leaks, use the J 41413-200 Evaporative Emissions System Tester (EEST) to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT High Intensity White Light. Introducing smoke in 15 second intervals will allow less pressure into the EVAP system. When the system is less pressurized, the smoke will sometimes escape in a more condensed manner.
• To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT .
• Observe the Freeze Frame/Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition occurs that caused the DTC to set. This may assist in diagnosing the condition.

The vent solenoid is right on the charcoal canister underneath the vehicle towards the rear however the bolts are usually seized and damage occurs during the process of removal requiring at times a whole canister assembly. At least they do in the northeast.

hi its evaporation leak detected fuel vapor recycling it gives either canister assembly ,or just canister vent valve if there is no leaks in the canister u could replace the vent valve only avail at autoparts danny

Help trouble locating vapor canister vent valve on 2006 Lincoln Navigator 5.4L

maybe what you have is not vapour lock as such but a vacuum forming in the tank and not allowing the fuel to be pumped to the injectors. I would be checking the canister and canister controls to ensure adequate venting. I f the fuel tank has been continuously filled to the filler neck then fuel can contaminate the canister and not allow it to work properly. In short I would be looking for reasons in that area Run fault code check and see if any fuel related problems are presented.

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemhttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA - Manifold Absolute Pressure Sensor Circuit Low Voltagehttp://engine-codes.com/p0107_honda.htmlForum CodePossible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM) When is the code detected?An excessively low voltage from the sensor is sent to ECMSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

PO 441 -is an EVAP System problem

The Check Light tells you that your vehicle
has a system Malfuntion. Have it diagnosed

You can not do EVAP at home too well

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.

The vapor canister is located under the vehicle near the fuel tank.
It is made out of black plastic and has plastic lines running to it.

The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.

Code P1443 Possible Causes:

- Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister

- Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister purge valve

Notes: Check for audible vacuum noise in the engine compartment or significant fuel odor in the engine compartment or near the EVAP canister.

On my '98 4x4, the cannister purge valve is located under the hood, mounted on the driver's side fender.

The EVAP cannister itself is located underneath the truck, in back, between the spare tire and the truck bed (have to remove the spare to get at it).

If it were me I would hold off on replacing parts...I'd drive around some more first, making sure that I don't overfill the gas tank or run it dry and making sure I replace the gas cap properly, etc. If the code returns, then its time to think repairs.
