CCV Fitting See Figures 2 and 3 1. With the engine running, remove the CCV fitting. a. If the fitting is not plugged, a hissing noise will be heard as air passes through the valve. A strong vacuum should also be felt when a finger is placed over the fitting. b. Install the CCV fitting. c. Remove the fresh air hose from the air cleaner assembly and loosely hold a piece of paper over the open end of the hose. After allowing about one minute for the crankcase pressure to reduce, the paper should be sucked against the opening with a noticeable amount of force. 2. Turn the engine OFF . Remove the metered orifice fitting, and check for a plugged condition. A clicking noise should be heard to indicate that the valve mechanism is free. 3. If the crankcase ventilation system meets the tests in Steps 1 and 2 above, no further service is required. If not, the CCV fitting must be cleaned and the system checked again. 4. If Step 1c fails when the CCV fitting is cleaned, it will be necessary to replace the molded vacuum hose with a new one, and to clean the metered orifice port. 5. Clean or replace the engine air cleaner filter element with a new one-for more details, refer to the air cleaner procedure located in General Information & Maintenance. Fig. 2: CCV system diagram for 4.0L engine Fig. 3: CCV system diagram for the 2.5L engine Evaporative Emission Control System OPERATION The evaporative emission control system prevents the release of unburned hydrocarbons, from gasoline or gasoline vapor, into the atmosphere. When pressure in the fuel tank is below 3 psi (20 kPa), the pressure relief/rollover valves open allowing fuel vapors to flow to the evaporative canister where they are absorbed by a charcoal mixture. This prevents excessive pressure buildup in the fuel system. Most canisters are equipped with a calibrated orifice at the inlet to the canister.

SERVICE PROCEDURE Replace Starter, Add Cleaner 1. Replace the starter motor. • Use the part number from the Parts Information section of this bulletin. • Refer to section SC, “STARTING SYSTEM, Removal and Installation” in the applicable Nissan Electronic Service Manual (ESM). 2. Add one full can of Nissan In-Tank Fuel System Cleaner to the fuel. NOTE: If the fuel tank is less than ¾ full, instruct the customer to fill the tank as soon as it is convenient after the repair. Driving with the Cleaner installed and low fuel level will not harm the fuel system or engine, but will reduce the effectiveness of the cleaning process. 3. Continue to ECM Part Number Check (next page). 1. With CONSULT-II “ON”, print the Self-DIAG Results as follows: START (Nissan) >> ENGINE >> Self-DIAG Results >> PRINT SELF-DIAG RESULTS SYSTEM ENGINE DATE XX/XX/XXXX* 11:07:11 P/N 23710-XXXXX TP020389h DTC RESULTS TIME NO DTC IS DETECTED Current ECM Part Number * Example, your screen may differ. 3.

Non-Enhanced EVAP System Diagnostic Procedure 1. Pinch off or plug the EVAP vapor line to seal the EVAP system. 2. Connect the EEST red battery clip to the positive (+) battery terminal. Connect the black battery clip to chassis ground. 3. Install the appropriate fuel fill cap adapter to the fuel fill pipe. Refer to the Service Information for the appropriate fuel fill cap adapter part number. 4. Connect the EEST’s nitrogen/smoke supply hose and vehicle fuel fill cap to the adapter. 5. Turn the nitrogen/smoke valve on the EEST control panel to SMOKE. 6. Use the remote switch to introduce smoke into the EVAP system for 60 seconds. Important: Additional smoke may need to be introduced at 15-second intervals until the leak source has been located. 7. Inspect the entire EVAP system for exiting smoke using the high intensity white light (J 41413-SPT). Enhanced EVAP System Leak Detection Procedure When diagnosing DTCs P0440, P0442, P0446 and P0455, use the J 41413-200 EEST along with 1. Turn ON the ignition with the engine OFF. 2. Command the EVAP vent valve closed with a scan tool.* *Prizm: In order to seal the EVAP system on the 1998-2002 Prizm, bypass the EVAP canister by connecting the fuel tank vapor hose to the canister purge line. Refer to the Service Information for additional information. 3. Connect the EEST red battery clip to the positive (+) battery terminal. Connect the black battery clip to chassis ground. 4. Install the appropriate fuel fill cap adapter to the fuel fill pipe. Refer to the Service Information for the appropriate fuel fill cap adapter part number. 5. Connect the EEST’s nitrogen/smoke supply hose and vehicle fuel fill cap to the adapter. 6. Turn the nitrogen/smoke valve on the EEST control panel to SMOKE. 7. Use the remote switch to introduce smoke into the EVAP system. 8. Use the J 41413-VLV EVAP Port Vent Fitting tool to open the EVAP service port (if equipped) until smoke is observed. 9. Remove the J 41413-VLV EVAP Port Vent Fitting tool once smoke is observed. Important: Additional smoke may need to be introduced at 15-second intervals until the leak source has been located.
