Component Inspection

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




4. Is resistance within specifications?
YES
1) Go to "CHECK PCM/TCM " as below
NO
1) Replace "OUTPUT SPEED SENSOR (PG-B)" as necessary and Go to "Verification Vehicle Repair" procedure
Check PCM/TCM
1. Ignition "ON" & Engine "OFF".
2. Connect "OUTPUT SPEED SENSOR (PG-B)" connector.
3. Install scantool and select a SIMU-SCAN,
4. Simulate frequency to "OUTPUT SPEED SENSOR (PG-B)" signal circuit.




5. Is "OUTPUT SPEED SENSOR (PG-B)" signal value changed according to simulation frequency?
YES
1) 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
1) Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and go to "Verification of Vehicle Repair" procedure.
