Signal Circuit Inspection

■ Short Circuit Inspection 

1. Ignition "OFF".
2. Disconnect "ATM solenoid valve connector and PCM/TCM connector.
3. Measure a resistance between signal of Output speed sensor and chassis ground.

   Specification:  Infinite

4. Is the measured resistance within specifications?

   YES 

   • Go to "Open Circuit Inspection" procedure below.

   NO 

   • Check harness for short circuit. Repair as necessary and go to "VERIFICATION VEHICLE REPAIR " procedure.
