Section 03-13: Evaporative Emissions 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DESCRIPTION AND OPERATION Evaporative Emission Canister Fuel vapor emitted through the evaporative emission valve (9B593) is stored in two evaporative emissions canisters (EVAP canister) (9D653) . I think you should have 2 engine vacuum lines, one for each canister.


Evaporative Emission Canister Purge Valve


---------------------------------------------------------------
Evaporative Emission Tube Shut Off Valve The evaporative emission tube shut off valve (9G332) is located in-line between the evaporative emission valve (9B593) and the evaporative emissions canister (EVAP canister) (9D653) . The evaporative emission tube shut off valve control valve is mounted on the fuel tank (9002) by an integral bracket. The evaporative emission tube shut off valve closes the flow path from the evaporative emission valve to the evaporative emissions canister during refueling to prevent overfilling of the fuel tank .

Evaporative Emission Tube Shut Off Valve

Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

Evaporative Emission Purge Solenoid

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

1. Disconnect electrical connector at solenoid.
2. Disconnect vacuum lines at solenoid.

The evaporative emissions system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Canister Closing Valve (CCV) closes off the air inlet into the canister for leak detection of the evaporative emission system. The CCV also prevents fuel vapors from escaping from the canister. When the engine purges the HC vapors from the canister, the clean air comes into the canister through the canister air-filter and the CCV.

1. Ignition "OFF". 2. Disconnect CCV connector. 3. Measure resistance between terminals 1 and 2 of the CCV connector(Component side). Specification : Approx. 23~26Ω at 20°C(68°F)
4. Is resistance within the specification? YES ▶ Go to next step as below. NO ▶ Check CCV for contamination, deterioration, or damage. Substitute with a known-good CCV and check for proper operation. If the problem is corrected, replace CCV and then go to "Verification of Vehicle Repair" procedure.Terminal and Connector Inspection

Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
