| 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
