ON-VEHICLE SERVICE
IGNITION COIL (WITH BUILT-IN POWER TRANSISTOR) CHECK <4G6-SOHC, 4G6-DOHC >
Check by the following procedure, and replace if there is a malfunction.
SECONDARY COIL RESISTANCE CHECK
   
Measure the resistance between the high-voltage terminals of the ignition coil.
Standard value: 8.5 - 11.5 kΩ
PRIMARY COIL AND POWER TRANSISTOR CONTINUITY CHECK
NOTE: 
       
    • An analogue-type circuit tester should be used.
    • Connect the negative (-) prove of the circuit tester to terminal No. 1.
     CAUTION
     This test must be performed quickly (in less than 10 seconds) to prevent coil from burning and power transistor from breakage.
    1.5 V power supply between 2 - 3
    		 Continuity between 1 - 2
    When current is flowing
    		 Continuity
    When current is not flowing
    		 No continuity
