A-07 harness ZK603170AA00 2 1 3 4 (3) Measure the voltage between terminal No. 2 and ground. ⦆ Voltage should be battery positive voltage. (4) Turn the ignition switch to the "LOCK" (OFF) position. Q:Is battery positive voltage (approximately 12 volts) present? YES: Go to Step 4. NO: Repair harness wire between the MFI relay connector A-33X (terminal No. 2) and the mass airflow sensor A-07 STEP 4. Check for open circuit or short circuit to ground (1) Disconnect the mass airflow sensor A-07 and the ECM ZK604075 82 81 80 79 78 77 76 75 74 73 72 71 94 93 92 91 90 89 88 87 86 85 84 83 99 98 97 96 95 100 101 102 103 104 105 106 112 113 114 109 108 107 110 111 115 116 117 118 2 1 3 4 A-07 harness connector: B-11 harness connector: AA00 (2) Measure the resistance between the mass airflow sensor ⦆ Should be less than 2 ohms. A-07 harness ZK603171AA00 2 1 3 4 (3) Check for the continuity between the mass airflow sensor ⦆ Not continuity. Q:Is the harness wire in good condition? YES: Go to Step 5. NO: Repair it. Then go to Step 6. STEP 5. Replace the mass airflow sensor. (1) Replace the mass airflow sensor. (2) Carry out a test drive with the drive cycle pattern.
