ON-VEHICLE SERVICE TSB Revision MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE> 13A-479 MULTIPORT FUEL INJECTION (MFI) RELAY AND M1131009900061 INTAKE AIR TEMPERATURE SENSOR CHECK M1131002800052 1. Disconnect the volume air flow sensor connectors. 2. Measure resistance between terminals 5 and 6. Standard value: 5.3 − 6.7 k Ω [at 0 ° C (32 ° F)] 2.3 − 3.0 k Ω [at 20 ° C (68 ° F)] 1.0 − 1.5 k Ω [at 40 ° C (104 ° F)] 0.30 − 0.42 k Ω [at 80 ° C (176 ° F)] 3. If not within specifications, replace the volume air flow sensor. 4. Measure resistance while heating the sensor using a hair dryer. Normal condition: 5. If resistance does not decrease as heat increases, replace the volume air flow sensor assembly. ENGINE COOLANT TEMPERATURE SENSOR M1131003100056 CAUTION Be careful not to touch the connector (resin section) with temperature sensor.
