Component Inspection

Check "INPUT SPEED SENSOR (PG-A)"
1. Ignition "OFF".
2. Disconnect the "INPUT SPEED SENSOR" connector.
3. Measure resistance between terminal "1" and "2" of the "INPUT SPEED SENSOR" connector.
  Specification: 245 ± 30 Ω /20°C (68°F)

4. Is resistance within specifications?
  YES : --> Go to step 2.
  
  NO : --> Replace "INPUT SPEED SENSOR" as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
CHECK PCM
1. Ignition "ON" & Engine "OFF".
2. Connect "INPUT SPEED SENSOR" connector.
3. Install scan tool and select SIMU-SCAN mode.
4. Simulate frequency to INPUT SPEED SENSOR signal circuit.

5. Is "INPUT SPEED SENSOR (PG-A)" signal value changed according to simulation frequency?
  YES : --> Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  
  NO : --> Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
