6. Ignition coil resistance
The following procedure applies to all of the
ignition coils.
• Disconnect the ignition coil leads from the
wire harness.
• Connect the pocket tester (Ω × 1) to the
ignition coil as shown.
Positive tester probe → black/red
Negative tester probe →
black/orange (black/white)
• Measure the primary coil resistance.
Primary coil resistance
1.31 ~ 1.79 Ω at 20 °C (68 °F)
• Connect the pocket tester (Ω × 1k) to the
ignition coil as shown.
Negative tester probe → spark plug lead 1
Positive tester probe → spark plug lead 2
• Measure the secondary coil resistance.
Secondary coil resistance
12 ~ 18 kΩ at 20 °C (68 °F)

7. Crankshaft position sensor resistance
• Disconnect the crankshaft position sensor
coupler from the wire harness.
• Connect the pocket tester (Ω × 100) to the
crankshaft position sensor coupler as
shown.
Positive tester probe → gray 1
Negative tester probe → black 2
• Measure the crankshaft position sensor
resistance.
Crankshaft position sensor
resistance
248.0 ~ 372.0 Ω at 20 °C (68 °F)
(between gray and black)
• Is the crankshaft position sensor OK?
YES
