MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-371 STEP 4. Check the idle air control motor coil resistance. connector terminal 2 and either terminal 1 or terminal 3. Standard value: 28 − 33 ohm [at 20 ° C (68 ° F)] (3) Measure the resistance between idle air control motor connector terminal 5 and either terminal 4 or terminal 6. Standard value: 28 − 33 ohm [at 20 ° C (68 ° F)] Q: Is the resistance normal? YES : Go to Step 5. STEP 5. Check the power supply voltage at idle air control side. (2) Turn the ignition switch to the "ON" position. • Voltage should be battery positive voltage. (4) Turn the ignition switch to the "LOCK" (OFF) position. Q: Is the voltage normal? YES : Go to Step 7. ACX02523AI IDLE AIR CONNECTOR:B-34 AKX01561 1 2 3 1 2 3 AB AKX01428 1 2 3 5 4 6 B-34 HARNESS AF |
