(See01-14-5 FUEL LINE PRESSURE • Is the low side fuel pressure within the specification? Yes Go to the next step. No Inspect for the following. • Fuel line restriction • Fuel filter clogging If normal replace the fuel pump.Then go to Step 26. 25 INSPECT SEALING OF ENGINE COOLANT • Perform “ENGINE COOLANT LEAKAGE INSPECTION.” • Is there any malfunction? Yes Repair or replace the malfunctioning part according to the No Go to the next step. 26 VERIFY TROUBLESHOOTING OF MISFIRE DTC • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the memory using the M- MDS. • Perform the HO2S heater, HO2S, and TWC Repair Verification Drive Mode. • Is the PENDING CODE for this DTC present? Yes Replace the PCM, then go to the next step. No Go to the next step. 27 VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See01-02-10 AFTER REPAIR • Are any DTCs present? Yes Go to the applicable DTC troubleshooting. No Troubleshooting completed. STEP INSPECTION ACTION DTC P0301 Cylinder No.1 misfire detected DETECTION CONDITION • The PCM monitors the CKP sensor input signal interval time. The PCM calculates the change of interval time for each cylinder. If the change of interval time exceeds the preprogrammed criteria, the PCM detects Diagnostic support note • This is a continuous monitor (Misfire). • The MIL illuminates if the PCM detects a misfire which affects emission performance in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • The MIL flashes if the PCM detects a misfire which can damage the catalytic converter during the first drive cycle. • PENDING CODE is available if the PCM detects a misfire which affects emission performance during first drive cycle. • FREEZE FRAME DATA is available. • DTCs are stored in the PCM memory. POSSIBLE CAUSE • Spark plug malfunction • Ignition coil malfunction • Ignition system malfunction • Fuel injector malfunction • Air suction in intake air system (between dynamic chamber and cylinder head) • Inadequate engine compression due to engine internal malfunction • Related connector or terminal malfunction • Related wiring harness 1871-1U-06B(01-02).fm 119 ページ 2006年3月15日 水曜日 午前10時32分 |
