Ignition Coil Resistance

On 3000GT DOHC, go to next step. On Montero and Montero Sport, use DVOM to measure primary coil resistance between each individual coil. To check secondary coil resistance, measure resistance between towers of each individual coil. Replace coil if primary and secondary coil resistances are not within specification. See IGNITION COIL RESISTANCE (V6) table.

IGNITION COIL RESISTANCE (V6) - Ohms @ 68°F (20°C)

Application	Primary	Secondary
3.0L
VIN H	.74-.90	20,100-27,300
VIN J & K	.67-.81	11,300-15,300
3.5L (VIN R)	.74-90	20,100-27,300

Using DVOM, measure primary coil resistance between terminal No. 3 (power terminal) and each individual coil terminal. See Fig 1. Terminal No. 1 controls coil "B", terminal No. 2 controls coil "A", and terminal No. 4 controls coil "C". See Fig 2. To check secondary coil resistance, measure resistance between towers of each individual coil. Replace coil if primary and secondary coil resistances are not within specification. See IGNITION COIL RESISTANCE (V6) table.
