An active gas warning light when the vehicle has plenty of gasoline.

Can you test an ignition coil with a multimeter?

Ignition coils have two circuits that require checking; primary and secondary circuits. Connect the multimeter to the negative and positive terminals of the ignition coil to get a primary circuit reading. If the multimeter shows a reading of 0 ohms, the ignition coil has shorted and needs replacing.

With all the wires taken off the terminals of the coil attach the positive and negative probes of the meter to first the negative terminal then the positive terminal on the coil. You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5.

How do you check if a coil is firing?

If you suspect the coil is dead, you can also remove the coil, plug it back in, and use an ignition spark tester like OEM 25069 to determine if the coil is firing. You can also use a multimeter to test resistance.

How do I know if my coil is getting power?
