Is it infinity? 		 Pressure control solenoid valve circuit is open circuit. If circuit is OK, go to Step 4. Go to Step 4.
4  Check pressure control solenoid valve 
  1. Check pressure control solenoid valve referring to SOLENOID VALVES (SHIFT SOLENOID-A, SHIFT SOLENOID-B, TCC PRESSURE CONTROL SOLENOID AND PRESSURE CONTROL SOLENOID) INSPECTION .

Is check results satisfactory? 		 Intermittent trouble or faulty TCM. Check for intermittent trouble referring to INTERMITTENT AND POOR CONNECTION INSPECTION . If OK, substitute a known-good TCM and recheck. Replace defective pressure control solenoid valve referring to SOLENOID VALVES (SHIFT SOLENOID-A, SHIFT SOLENOID-B, TCC PRESSURE CONTROL SOLENOID AND PRESSURE CONTROL SOLENOID) REMOVAL AND INSTALLATION .
