This is a shrader vale, much like the valve on a tire valve stem. you can purchase a valve stem remover tool and tighten it up. A cap will not take care of your problem. Please take care of this as soon as possible, This can cause an engine fire.

HOW DO I FIX THIS CODE P1738 AND P1456? RECENTLY HAD TRANSMISSION REBUILT AND RIGHT FRONT AXLE.


Best to clear the computer codes & see what codes if any come back. You will need a scanner that can clear codes to do it .. Or if there is an Auto Value around you they can do it.

If P1738 returns I would bring the car back to the transmission shop.

I put the code details below.

P1738: Problem in 2nd Clutch Pressure Switch Circuit

P1456: Evaporative Emission Control System Leak Detected 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
- Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve.

Po 442 po 455


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.

Codigo p1440


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).
