Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ignition Coil Primary Resistance
Disconnect ignition coil 3-pin connector (located in front of intake manifold). Disconnect ignition coil power output stage 3-pin connector (located on right side of engine compartment). See Fig 1 . Measure resistance between any terminal of ignition coil 3-pin connector and power output stage 3-pin connector terminal No. 3. See Figure and Figure . Maximum allowable resistance is 5 ohms. If resistance is not within specification for any coil, replace ignition coil assembly.
