2 6525 EVAP Approved

3 Enhanced EVAP Phase-in % % % % Manufacturers with sales less than 10,000 vehicles per year are exempt until 1999 when 100% compliance is required.

4 The typical non-enhanced EVAP system contains the following components: EVAP emission pressure control valve. Vented canister. Diagnostic switch EVAP purge solenoid. Do you see the words “Gas Cap” here?

5 The Enhanced EVAP System uses the following components: Evaporative system canister. Fuel tank pressure sensor. Canister purge solenoid. Canister vent solenoid. Service port. Fuel cap. Fuel level sensor. Do you know anybody that has changed a gas cap?

6 Using an EVAP-approved smoke machine isn’t just recommended, it’s now required by DaimlerChrysler, Ford, General Motors, Land Rover, Saab and Saturn. More approvals are pending.

8 1.P % System too lean -- Bank 1 2.P % Ford EVAP Control Valve Failure 3.P % Gross EVAP Leak 4.P % O2 Sensor Heater Circuit 5.P % O2 Sensor Heater 6.P % Misfire Cylinder #1 7.P % Random Misfire 8.P % Low Catalyst Efficiency – Bank 1 9.P % O2 Sensor No Activity 10.P % Camshaft Pos. Sensor Malfunction This information is from the Clean Air Conference 2002 Breckenridge, Colorado Top 10 DTCs in Vehicles with Less Than 75,000 Miles (CA) The right tool for the top three most common Codes

9 Unlike traditional general-purpose smoke machines, the EVAP-approved units use an inert gas like Nitrogen for testing the EVAP systems. Where can you get a Nitrogen tank ? 800-PRAXAIR ( ) Enter Zip Code How Long Will A Tank Last ? 300 cu-ft. = Minutes Tests You can use shop air for all general purpose leak testing.

10 Do you sell this with the 6285 LeakTamer? Why not?

11 Caution Clockwise to remove Must remove core and DON’T LOOSE IT ! Put smoke supply hose in good and tight Now we are ready to find leak(s)

12 Intake Manifold Charcoal Canister Purge Valve Disconnect the hose between the Purge Valve and Charcoal Canister, at or as close as you can to the Purge Valve. Insert the EVAP tester supply line into the hose that is going to the Charcoal Canister. Close “Canister Vent Valve” and continue testing the system. Canister Vent Valve When smoke is put into the EVAP system (Canister Close Valve is closed) there should NOT be any smoke exiting the Canister Close Valve. This test procedure doesn’t test from the Purge Valve back to the engine. Canister Vent Valve Fuel Tank No EVAP test port? This test is done with key on engine off

13 The EVAP system is NOT to be tested with more than 13 ” of Water Column (less than 1/2psi). The OE-approved machines have a built-in regulator to handle this task. Caution General purpose smoke machines can produce 3 to 5 times more pressure than recommended by the manufacturers. Over pressuring the system can and will cause damage! Look at the tag on the service port 1psi Max

14 Future TESTSMOKE.040 ’’. 020 ’’ FAIL / ÉCHEC / FALLA PASS / SUCCÈS / PASE Observe reading after ball stops descending

15 The power of Quantifying PO442 =.040 ”(Small Leak) PO456 =.020 ”(Very Small Leak) OE-approved EVAP machines have the ability to quantify both PO442 & PO456 codes and give you a pass / fail test in less than 2 minutes Example: Select the setting of.040 ” or.020 ” and adjust the red flag to calibrate to that setting. Put the unit in the test mode and push the remote button. With the canister vent valve closed, wait for the ball to stop descending. If the ball stops above the red flag, the leak(s) are greater than calibrated. Fail Pass
