Test Procedures
TEST PROCEDURE 15 – Ignition Coil
See General Warnings on page 1-2.
NOTE: This is a resistance test.
The following test procedures will properly detect a coil that has failed in most cases; however, in rare cases, some
ignition coils can fail to operate at normal (warmer) operating temperatures. If the ignition coil has tested okay in
the vehicle and on the bench, but fails to operate reliably, replace the coil with a known good coil and operate the
engine for several minutes to ensure that the coil functions at normal operating temperature. If the new coil functions
properly, keep the new coil in the circuit.
NOTE: Resistance value ranges given in these tests reflect a tolerance of ±40%.
Please note that these values are rough standard and it is impossible to reach an exact conclusion with
the resistance reading.
1. If necessary, see Testing Basics on page 18-14.
2. Disconnect battery and spark plug wire(s). See Side-Post Battery: Disconnecting the Battery-Gasoline
Vehicles on page 1-3.
See Top-Post Battery: Disconnecting the Battery- Gasoline Vehicles on page 1-4.
3. At engine, access white wire in ECU wire harness that connects to ignition coil lead at back of engine.
4. Using a multimeter set to 200k ohms, measure resistance between the following locations listed in table below.
