2002 Ford Explorer Evaporative Emission Repair Verification Drive Cycle


Filed Under (Ford) by admin on 24-02-2011

Drive Cycle Recommendations NOTE: The following procedure is designed to execute and complete the evaporative emission repair verification drive cycle and to clear the Ford P1000, inspection and maintenance (I/M) readiness code. When the ambient air temperature is below 4.4°C (40° or above 37.8° (100° or the altitude is above 2,438 meters (8,000 feet), the EVAP monitor will not run. If the F) C F), P1000 must be cleared in these conditions, the powertrain control module (PCM) must detect them once (twice on some applications) before the EVAP monitor can be bypassed and the P1000 cleared. The EVAP bypassing procedure is described in the following drive cycle. 1. Most OBD II monitors will complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth fashion will minimize the time necessary for monitor completion. 2. Fuel tank level should be between one-half and three-quarters full with three-quarters full being the most desirable. 3. The evaporative monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize fuel slosh. Drive Cycle Preparation NOTE: For best results, follow each of the following steps as accurately as possible. 4. NOTE: This step bypasses the engine soak timer and resets OBD II monitor status. Install the scan tool. Turn the key ON with the engine OFF. Cycle the key off, then on. Select the appropriate vehicle and engine qualifier. Clear all diagnostic trouble codes (DTCs) and carry out a PCM reset. 5. Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE. Press Diagnostic Data Link, PCM, PID/Data monitor and record, press trigger to select each PID, then start. 6. Start the engine without returning the key to the OFF position. Preparation for Monitor Entry WARNING: Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the following drive cycle. 7. NOTE: This step allows engine warm-up and provides intake air temperature (IAT) input to the PCM. Idle the vehicle for 15 seconds. Drive at 64 km/h (40 mph) until the ECT is at least 76.7° (170° C F). 8. Is IAT above 4.4° (40°F) and below 37.8°C (100° C F)? If not, continue with the following steps but note that the EVAP Monitor Bypass portion of the drive cycle (step 13) will be required to bypass the EVAP monitor and clear the P1000. 9. NOTE: This step executes the heated oxygen sensor (HO2S) monitor. Cruise at 64 km/h (40 mph) for 60 seconds. 10. NOTE: This executes the EVAP monitor if IAT is above 4.4°C (40° and below 37.8° (100°F). F) C NOTE: To initiate the monitor, TP MODE should equal PT, EVAPDC must be greater than 75%, and FLI must be between 15 and 85%. NOTE: Avoid sharp turns and hills. Cruise at 72 to 104 km/h (45 to 65 mph) for 10 minutes. 11. NOTE: This step executes the ISC portion of the Secondary Air/CCM. Bring the vehicle to a stop. Idle with the transmission in DRIVE (for automatic transmission) or NEUTRAL (for manual transmission) for two minutes. Pending Code and EVAP Monitor Bypass Check 12. NOTE: This determines if a pending code is preventing the clearing of P1000. NOTE: If the EVAP monitor is not complete and IAT was below 4.4° (40° or above 37.8° (100°F) temperature range in Step 8, or the altitude is above 2,438 meters (8,000 feet), C F) C the EVAP Monitor Bypass (Step 13) must be carried out. Using the scan tool, check for pending codes. Conduct normal repair procedures for any pending code concerns. Rerun any incomplete monitor. EVAP Monitor Bypass 13. NOTE: This allows the bypass counter to increment to two. NOTE: Do not repeat Step 4. Park the vehicle for a minimum of eight hours. Repeat Steps 5 through 12.

WATER LEAK AT FRONT FLOOR ’02 – ’06 Toyota Camry (TMMK), ’04 – ’06 Toyota Solara Coupe, & ’05 – ’06 Toyota Avalon

Some customers may experience a water leak at the front floor area. Water may be Introduction entering the body due to a body sealer void on the engine compartment rear wall, near the upper door hinge. Repair 1. Raise the vehicle. On the side of the vehicle that has the water leak, remove the front Procedure wheel and the front fender plastic liner. 2. Examine (with flash light and mirror) the body sealer condition on the engine compartment rear wall, near the upper door hinge. Also examine the sealer condition inside the inner fender box frame structure with access holes (see illustration).

Removing the stock air inlet system
a) Before removing any of the O.E. components, label each individual part so that no components become mixed up during the installation process. There are two Vacuum Switching Valves (VSV), and one air flow meter that have electrical and/or vacuum connections going to them. Be sure to label these connections before disconnecting them.
Remove b) Remove the two nuts and two plastic rivets that hold the plastic engine cover on. The
plastic rivets may be gently lifted with a small screwdriver. Remove the cover. c) Remove the bolt in the radiator support that holds the battery bracket. Unhook the rod at the rear of the battery bracket. Remove the battery from the vehicle

Theory of Operation The State of Change (SOC) catalyst monitor uses the signals from both the upstream and downstream O2 sensors to detect aging of the catalyst. Based on the fact that when a catalyst ages, it loses some of its Oxygen Storage Capacity (OSC). As a result, part of the untreated exhaust gases can breakthrough the catalyst and causes the downstream O2 sensor to deviate from its neutral (Stoichiometric) position. By observing the activities in the downstream O2 signal, the degradation level of catalyst can be detected. In general, the higher the downstream O2 sensor SOC value, the more exhaust gas breakthrough and the lower the OSC of the catalytic converter. WHEN MONITORED The monitor will run at between 1400 and 2300 RPM . It also runs between 40 and 70 KPA . SET CONDITION If the final State of Change index is within the calibrated fail threshold. Two trip fault. Three good trips to turn off the MIL
