Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Ignition Coil E Primary Control Circuit High
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.
The primary control circuit of ignition coil E reads a voltage above the expected level — typically an open primary circuit or a short to battery voltage on the primary control wire. The ECU sees no normal current flow, coil E does not fire, and the cylinder misfires. Causes: an open or disconnected primary wire, an internal open in the coil, or a faulty ECU driver.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
