Filler valve won't shut off. How do I fix it?

Ed,

We would love to help you out!

First,check the oil level is to the very top of the filler as these have an automatic shut off if the oil gets too low. They like to be filled to the very top of the filler hole. Try running it, if it still shuts down let us know and we will assign an Engineer to your case. :)

code p1456 refers to evaporative emission (EVAP) canister purge system(fuel tank system) -leak detected===causes--hose-fuel tank/pressure sensor--fuel filler cap--EVAP valve /bypass solenoid--EVAP two way valve---EVAP canister/vent valve

There is also a second reference to the code which is EVAP system leakage ====filler cap--EVAP canister purge valve--hoses---EVAP canister shut off valve---ECM programming---ECM

Check with the service dealer that the filler caps are interchangeable . It may be coincidence that the problem started after you changed caps or it may have shown a failure in the making

take the fuel tank filler neck out and check for an obstruction

Hi there?
It sounds like the EGR valve is stuck open letting the exhaust fumes enter the engine. Since the exhaust smoke has no oxygen then the engine won't start whout oxygen (fresh air). Disconnect the pipe going to the inlet manifold and see if the engine starts. If it starts then you need a new EGR valve.

don't trust anyone who can't spell fuel.

P0442 - Evaporative Emissions System Leak Detected (Small Leak)

P0455 - Evaporative Emissions System Leak Detected (Gross Leak)

This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum. If pressure does not increase, the 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.

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
- Incorrect fuel tank vacuum relief valve
- Leak is in line between intake manifold

Solutions:
- Re-tighten or replace fuel tank filler cap
- Replace damaged or leaking EVAP canister
- Replace damaged or leaking lines.

EVAP System Vent Circuit Malfunction

This diagnosis detects leaks in the Evaporative Emission (EVAP) purge line using of vapor pressure in the fuel tank. The EVAP canister vent control valve is closed to shut the EVAP purge line. The vacuum cut valve bypass valve will then be opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP control system pressure sensor can now monitor the pressure inside the fuel tank. If pressure increases, the Engine Control Module (ECM) will check for leaks in the line between the vacuum cut valve and EVAP canister purge volume control solenoid valve.

Possible causes
- Incorrect fuel tank vacuum relief valve
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve
- Foreign matter caught in EVAP canister vent control valve
- EVAP canister or fuel tank leaks
- EVAP purge line (pipe and rubber tube) leaks
- EVAP purge line rubber tube bent
- Blocked or bent rubber tube to EVAP control system pressure sensor
- Loose or disconnected rubber tube
- EVAP canister vent control valve and the circuit
- O-ring of EVAP canister vent control valve is missing or damaged
- EVAP canister is saturated with water
- EVAP control system pressure sensor
- Absolute pressure sensor

Possible solution
- Loose fuel filler cap
- Leaking fuel filler cap


Hope helps (remember to rate this answer).

Your scanner will give you the code but it will not tell you how to fix your vehicle. Scanners basically tell you what systems to check or what systems are failing.

These are what your codes mean:

P0700: Transmission Control Module
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module. This is just a informative code.

P0734: Gear ratio error in 4th gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0732: Gear ratio error in 2nd gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0731: Gear ratio error in 1st gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0871: Transmission Fluid Pressure Sensor Switch C

P0876: Transmission Fluid Pressure Sensor Switch D

Emissions Codes:

P0400: Exhaust Gas Recirculation Flow Malfunction
- Harness or connectors (EGR volume control valve circuit is open or shorted.)
- EGR volume control valve stuck closed
- EGR volume control solenoid valve
- Dead (Weak) battery
- EGR temperature sensor and circuit
- EGR Valve

How to fix :
- Clean EGR Valve
- Repair EGR harness or connector
- Replaced EGR volume control solenoid valve
- Replaced EGR volume control valve

P0440: EVAP Emission Control System Malfunction
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0456: EVAP Control System Leak Detected (Very Small Leak)
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0441: EVAP Emission Control System Incorrect Purge
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

Based on the info check your EVAP system. I would check for leaks and maybe replace the EGR and the canister.

For the transmission check the TCM also you may need to take it to a mechanic though.

Hope this helps a little.

The compressor will not auto shut off until it reaches the preset pressure which is usually around 100-130 psi - your problem is leakage of air from the oil filler cap suggesting that you have a failed internal valve.

hi you got a problem with the return pipe on the filler neck to the tank it proberly will have a non return valve on it causing a blockage so as your filling it creates a vacuum and won,t fill yates210456
