Drive the vehicle allowing speed to fluctuate between 3. Notes Maintain smooth throttle inputs, avoiding sudden accelerations. Avoid sudden deceleration with closed throttle as much as possible. EVAPORATIVE VACUUM PRESSURE TYPE MONITOR DRIVE CYCLECertain Models 2. Pre Conditioning Requirements MIL must be off. Fuel level is between 2 and 34 full. Preferred values monitor may still run with tank fill between 1. Altitude is below 7. ECT IAT is between 4. E F 4. 5 3. 5E C. Cold Soak Procedure is complete see below. MY vehicles will run monitor at temperatures below 1. E F by cycling key to OFF and repeating drive trace. IMPORTANT A cold soak must be performed prior to conducting the drive pattern in order to complete the Internal Pressure Readiness. Monitor see below. Cold Soak Procedure Let the vehicle sit 8 hours, or until the difference between IATand ECT is less than 1. E F 7. E C. Driving Procedure Connect Scan tool in order to observe data stream and monitor status. Release pressure in the fuel tank by removing and re installing fuel cap. Start the engine and allow it to idle until ECT is 1. E F 7. 5E C or more. Raise the engine speed to 3,0. Free Download Material Library 3Ds Max 9 Trial. RPM for ten 1. 0 seconds. Idle engine with the AC on for additional load for 1. If no AC, set parking brake and chock wheels. Once immobilized, idle vehicle in drive. EVAPORATIVE WITH NO LEAK DETECTION MONITOR DRIVE CYCLECertain Models 1. Pre Conditioning Requirements MIL must be off. Altitude is below 7. ECT is 1. 81. E F 8. E C or more. IAT is 4. E F 5. E C or more. Driving Procedure this is the same driving trace used by the EGR monitor. Connect Scan tool in order to observe data stream and monitor status. Drive the vehicle at a steady speed between 4. Notes Do not exceed 3. TPS. Maintain smooth throttle inputs, avoiding sudden accelerations. Stop the vehicle and idle the engine for 3 5 minutes. Repeat steps 1 3 once. OXYGEN SENSOR MONITOR DRIVE CYCLECertain models 1. Pre Conditioning Requirements Driving Procedure Connect Scan tool in order to observe data stream and monitor status. Drive the vehicle at a steady speed at or above 2. Maintain engine speed above 9. Stop the vehicle and allow the engine to idle for 4. Repeat steps 2 3 nine 9 more times.
