MULTIPORT FUEL INJECTION(MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <2.4L> 13A-405 STEP 3. Check the circuit at PCM connector C-41. harness side. (2) Turn the ignition switch to the "ON" position. • Voltage should be 1 volt or less when the A/C switch is • Voltage should be battery positive voltage when the A/C (4) Turn the ignition switch to the "LOCK" (OFF) position. Q: Is the voltage normal? YES : Replace the PCM. Then confirm that the malfunction symptom is eliminated. NO : Refer to GROUP 55, Heating and air conditioning −
Introduction To Heater, Air Conditioning And DATA LIST REFERENCE TABLE M1131008900109 CAUTION • When shifting the select lever to D range, the brakes should be applied so that the vehicle does • Driving tests always need two persons: one driver and one observer. NOTE: *1 : If the idle speed is lower than the standard value on a very cold engine (approximately -20 ° C (-4 °
F) even when the IAC motor is fully opened, the air volume limiter built in the throttle body could be defective. NOTE: *2 : In a new vehicle [driven approximately 500 km (311 mile) or less], the step of the stepper motor is sometimes 30 steps greater than the standard value. NOTE: *3 : The injector drive time represents the time when the cranking speed is at 250 r/min or below when the power supply voltage is 11 volts. NOTE: *4 : In a new vehicle [driven approximately 500 km (311 mile) or less], the injector drive time is sometimes 10% longer than the standard time. NOTE: *5 : In a new vehicle [driven approximately 500 km (311 mile) or less], the volume air flow sensor output frequency is sometimes 10% higher than the standard frequency. NOTE: *6 : Applicable to General Scan Tool (GST). AKX01449 71 72 73 74 75 76 77 90 91 92 93 94 95 96 97 98 C-41 HARNESS AE MUT-II ITEM NO.
