Evap system monitor 99 camry11/28/2023 It's simple as hooking up the interface and loading up TOAD PC/laptop software. TIP: Tune Your Car with Powerful Diagnostics Software Repeat steps 5 & 6 nine (9) more times.Drive the vehicle at a steady speed above 25 mph (40 km/h) or more for at least 40 seconds.Stop the vehicle and allow it to idle for ten (10) seconds or more.Maintain engine speed between 900 & 3,200 rpm. Drive the vehicle at a steady speed between 40-70 mph (64-112 km/h) or more for 3 minutes.Start the engine and allow it to idle 2 minutes.Repeat steps 2 & 3 nine (9) more times.ĪIR-FUEL RATIO (OXYGEN) SENSOR MONITOR DRIVE CYCLE.Stop the vehicle and allow the engine to idle for 40 seconds or more.Drive the vehicle at a steady speed at or above 25 mph (40 km/h) for at least 50 seconds.ECT is 181E F (83E C) or more.ĭriving Procedure: (this is the same driving trace used by the EGR monitor). EVAPORATIVE (WITH NO LEAK DETECTION) MONITOR DRIVE CYCLE Once immobilized, idle vehicle in drive). (If no A/C, set parking brake and chock wheels. Idle engine with the A/C on (for additional load) for 15-50 minutes.Raise the engine speed to 3,000 RPM for ten (10) seconds.Start the engine and allow it to idle until ECT is 167E F (75E C) or more.Release pressure in the fuel tank by removing and re-installing fuel cap.Let the vehicle sit 8 hours, or until the difference between IATand ECT is less than 13E F (7E C).Cold Soak Procedure is complete (see below).Ī cold soak must be performed prior to conducting the drive pattern in order to complete the Internal Pressure Readiness.(Preferred values- monitor may still run with tank fill between 15% and 85%).EVAPORATIVE (VACUUM PRESSURE TYPE) MONITOR DRIVE CYCLE Avoid sudden deceleration with closed throttle as much as possible. Notes: Maintain smooth throttle inputs, avoiding sudden accelerations. Drive the vehicle allowing speed to fluctuate between 35-45 mph (56-72 km/h) for 16 minutes.CATALYST (A/F SENSOR) MONITOR DRIVE CYCLE NOTES: Maintain smooth throttle inputs, avoiding sudden accelerations. Drive the vehicle at 35-45 mph (56-72 km/h) for 7 minutes.Drive the vehicle at a steady speed between 40-55 mph (64-88 km/h) or more for 7 minutes if IAT was below 50E F (10E C)Īt start-up, or 3 minutes if IAT was above 50E F (10E F) at start-up.(2002 MY vehicles will run monitor at temperatures below 14E F by cycling key to OFF and repeating drive trace). IAT (Intake Air Temperature) must be 14E F (-10E C) or more.ECT (Engine Coolant Temperature) must be 176E F (80E C) or more.Drive the vehicle at 25 mph (40 km/h) or more for at least 2 minutes.ĬATALYST (NON-A/F SENSOR) MONITOR DRIVE CYCLE. Start engine and allow it to idle for 9 minutes.AIR/FUEL SENSOR HEATER MONITOR DRIVE CYCLE Pending codes are not considered a failure, and typically must be duplicated in order to set a DTC & MIL. Toyotas do report pending codes (using an enhanced scan tool). Notes: Readiness may not switch to complete if a pending code was set during the drive trace. Stop the vehicle and idle the engine for 3-5 minutes.Drive the vehicle at a steady speed between 43 & 56 mph (70-90 km/h) for three to five minutes.Maintain smooth throttle inputs, avoiding sudden accelerations.Įxception: 1996-2000 Land Cruiser & LX 450- Begin driving immediately. If IAT is less than 50E F (10EC) at engine start-up, idle engine for 10 minutes.Connect Scan tool in order to observe data stream and monitor status.IAT (Intake Air Temperature) must be above 13E F (-10E C).It's possible that more tan one monitor may run while doing a particular drive trace, but here's the official procedure from Toyota/Lexus: EGR MONITOR DRIVE CYCLE Toyota/Lexus use a series of diferent drive traces for each system monitor.
