Is resistance within specifications?
 | ▶ Go to "CHECK PCM/TCM " as below. |
 | ▶ Replace "INPUT SPEED SENSOR" as necessary and Go to "Verification Vehicle Repair" procedure. |
Ignition "OFF"
Disconnect the "INPUT SPEED SENSOR" connector.
Measure resistance between terminal "1","3" of the "INPUT SPEED SENSOR1" connector.
Specification : Approx. "15~30 MΩ"
Is resistance within specifications?
| ▶ Go to "CHECK PCM/TCM " as below. |
| ▶ Replace "INPUT SPEED SENSOR" as necessary and Go to "Verification Vehicle Repair" procedure. |
Ignition "ON" & Engine "OFF".
Connect "INPUT SPEED SENSOR" connector.
Install scantool and slect a SIMU-SCAN.
Simulate frequency to INPUT SPEED SENSOR signal circuit.
Fig.1) 150Hz → 247rpm
Fig.2) 250Hz → 412rpm
Is "INPUT SPEED SENSOR" signal value changed according to simulation frequency?
| ▶ 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. |
| ▶ Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and then go to "Verification of Vehicle Repair" procedure. |
