P2319 Ignition Coil G Primary Control Circuit High
The primary control circuit of ignition coil G 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 G 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.
Is it safe to drive with P2319?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyOpen circuit in primary winding or harness for coil G
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
