MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <2.4L> 13A-169 STEP3. Check the throttle position sensor. (2) Measure the resistance between throttle position sensor side connector terminal No. 1 and No. 4. Standard value: 3.5 − 6.5 kΩ (3) Measure resistance between the throttle position sensor side connector terminal No. 1 and No. 3. (4) Move the throttle valve from the idle position to the full-open position. • Resistance should change smoothly in proportion to the opening angle of the throttle valve. Q: Is the resistance normal? YES : Go to Step 4. , Throttle Body. Then go to Step 14. STEP 4. Measure the sensor supply voltage at throttle side. (2) Turn the ignition switch to the "ON" position. (3) Measure the voltage between terminal No. 4 and ground. • Voltage should be between 4.8 and 5.2 volts. (4) Turn the ignition switch to the "LOCK" (OFF) position. YES : Go to Step 7.
