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 Primary Resistance

Disconnect ignition coil 3-pin connector (located in front of intake manifold). Disconnect power output stage 3-pin connector (located on right side of engine compartment firewall). Measure resistance between matching terminals of each connector (terminal No. 1 to 1, 2 to 2, and 3 to 3). See Fig 1 . If resistance is not 0.5-1.0 ohm, replace appropriate coil.
