ON-BOARD DIAGNOSTIC [L3 WITH TC] 01-02–231 01-02 End Of Sie DTC P2196[L3 WITH TC] id010239812800 15 INSPECT FUEL PRESSURE (LOW-SIDE) • Connect the fuel pressure gauge between fuel pump and high pressure fuel pump. • Measure the low side fuel pressure. (See01-14-5 FUEL LINE PRESSURE • Is the low side fuel pressure within the specified? Yes Go to the next step. No Inspect for following: • Fuel line restriction • Fuel filter clogging If okay replace the fuel pump. Then go to the next step. 16 VERIFY TROUBLESHOOTING OF DTC P2195 • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Perform the PCM Adopted Memory Produce Drive Mode and HO2S heater, and TWC • Is the PENDING CODE for this DTC present? Yes Replace the PCM, then go to the next step. No Go to the next step. 17 VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See01-14-4 AFTER REPAIR • Are any DTCs present? Yes Go to the applicable DTC inspection. No Troubleshooting completed. STEP INSPECTION ACTION DTC P2196 Front HO2S signal stuck rich DETECTION CONDITION • The PCM monitors the front HO2S output current when the following conditions are met. If the average output current is less than 0.85 A for 25 s, the PCM determines that the front HO2S has a malfunction. MONITORING CONDITION — ECT: more than 70— 150 °C {158— 302 °F} — Engine speed: 1,000— 3,200 rpm — Charging efficiency: 20— 62.5% — Output voltage from the rear HO2S: 0.8 V or less Diagnostic support note • This is an intermittent monitor (HO2S). • MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • DTCs are stored in the PCM memory. POSSIBLE CAUSE • Front HO2S malfunction • Fuel injector malfunction • Excessive fuel pressure • Fuel pressure sensor malfunction • Relief valve (built-in fuel delivery pipe) malfunction • Spill valve control solenoid valve (built-in high pressure fuel pump) malfunction • High pressure fuel pump malfunction • Restriction in intake-air system • MAF sensor malfunction • ECT sensor malfunction • PCM malfunction 1871-1U-06B(01-02).fm 231 ページ 2006年3月15日 水曜日 午前10時32分 |
