Lincoln E7DZ-9B593-A Valve Assembly - Fuel Vapour

You can Select Your Vehicle to check if E7DZ-9B593-A fits your vehicle.

This system prevents hydrocarbons from polluting the atmosphere by storing fuel vapor from the tank. It includes a charcoal canister, purge control solenoid, connecting lines, fuel cap, and fuel injection system. Vapor from the tank is stored in a charcoal canister located near the front wheel well until the engine starts. The canister connects to a purge solenoid, which opens at engine start to draw vapor into the air cleaner. The canister and solenoid should be checked for damage or malfunction and replaced if necessary. To replace the canister, remove the mounting bolt, lower the canister, detach the hose, and remove the canister. For other components, use the VECI label schematic to locate and replace them. Installation is the reverse of removal.

The Electronic Engine Control (EEC-IV) system features an onboard computer called the Electronic Control Assembly (ECA) and various information sensors that monitor engine functions and relay data to the ECA, which then generates output signals to manage engine operations. The ECA, positioned inside the dashboard near the steering column, acts as the system's brain, processing data from multiple sensors and electronic components to optimize emissions, fuel economy, and drivability. Due to a federally mandated warranty covering the ECA and its components, diagnosing or replacing the ECA at home is discouraged; professional service is recommended for malfunctions. Input sensors include the compressor clutch signal, Air Charge Temperature sensor, Engine Coolant Temperature sensor, Manifold Absolute Pressure sensor, barometric pressure sensor, oxygen sensor, Profile Ignition Pick-up, and Throttle Position Sensor, all of which provide critical data for engine management. Output devices controlled by the ECA include the A/C and cooling fan controller module, EEC power relay, canister purge solenoid, EGR control solenoid, fuel injectors, fuel pump relay, and Idle Speed Control motor, with the TFI ignition module managing ignition timing. Diagnosing issues with these sensors and devices typically requires specialized equipment, making it advisable to seek dealer service for any driveability concerns. Component replacement should generally be avoided while under warranty, but after expiration, procedures for replacing the Air Charge Temperature sensor, Manifold Absolute Pressure sensor, Exhaust Gas Oxygen sensor, and canister purge solenoid can be performed, with specific steps outlined for each. However, replacing the Throttle Position Sensor is not recommended due to the need for specialized calibration equipment.

In carbureted engines, vapor from the gas tank and sealed carburetor is routed to the canister through valves like the bowl vent solenoid and thermal vent valve.

1. Label all vacuum hoses and ports, then detach the hoses from the valve. 2. Remove the valve. 3. Apply vacuum to port B; the valve should be closed. If it is open, replace it. 4. Apply and maintain 16 in-Hg vacuum to port A, then apply vacuum to port B again. The valve should open. If it doesn't, replace it.

Vapor pressure is controlled by connecting a charcoal canister to vapor sources and integrating a vapor relief valve into the fuel tank.
