MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-99 STEP 3. Check the throttle position sensor. side connector terminal 1 and 4. Standard value: 3.5 − 6.5 k Ω (3) Measure resistance between the throttle position sensor side connector terminal 1 and 3. (4) Move the throttle valve from the idle position to the full-open position. • Resistance should change smoothly in proportion to the Q: Is the resistance normal? YES : Go to Step 4. , Throttle Body.) Then go to Step 9. STEP 4. Check the maladjusted throttle position sensor. Q: Is the output voltage normal? YES : Go to Step 5. STEP 5. Check connector C-58, C-62 at ECM <M/T> or YES : Go to Step 6. Connector Inspection ( ). Then go to Step 9.
