Ignition Coil H Primary Control Circuit High
The primary control circuit of ignition coil H 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 H 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.
Possible causes
- Open circuit in primary winding or harness for coil H high
- Connector pins corroded - high contact resistance low
- Supply wire pinched against B+ source low
