Ignition Coil L Secondary Circuit
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
A fault is detected on the secondary (high-voltage) side of ignition coil L. The spark delivered to the plug is missing or too weak, causing a misfire on the cylinder served by coil L. Causes: a worn spark plug or wide gap, a cracked coil or boot, carbon tracking, or an open or leaking secondary winding.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
