October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Ignition Coil (2.0L) Test
- Disconnect ignition coil connector. Using an ohmmeter, measure primary coil resistance between ignition coil terminals No. 4 and 2. Also measure resistance between ignition coil connector terminals No. 4 and 1. Perform TEST 1. See Fig 1
. Primary resistance should be .77-.95 ohms at 68°F (20°C).
- With ignition coil connector still disconnected, measure secondary coil resistance. Measure resistance between high voltage terminals for No. 1 and 4 cylinders, and between high voltage terminals for No. 2 and 3 cylinders. Perform TEST 2. See Fig 1
.
- Secondary resistance should be 10,300-13,900 ohms. Replace ignition coil if it does not test as described.
