P2316

Ignition Coil F Primary Control Circuit High

Ignition system Generic OBD-II Medium

What it means

P2316 means the engine computer detected high voltage in the primary control circuit of ignition coil "F." A fault here can stop that coil from firing its cylinder, causing a misfire, rough running, and reduced power. The usual culprits are the coil or its wiring and connector rather than internal engine problems.

Medium

Can I keep driving? Drivable but not ideal — the affected coil may not fire, causing a misfire that can, over time, damage the catalytic converter.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Corroded or loose connector at ignition coil F
  2. Control wire shorted to voltage or an open in the primary circuit
  3. Failed ignition coil F
  4. Poor ground or supply to the coil
  5. Failed PCM/ECM coil driver (less common)

How to diagnose & fix

Work through it in order

  1. Read freeze-frame data and identify which cylinder coil F serves for your engine.
  2. Inspect the coil connector and primary wiring for corrosion, shorts to voltage, and opens.
  3. Swap coil F with a known-good coil to see if the fault follows the coil.
  4. Check the coil's power and ground and the driver circuit back to the PCM.
  5. Replace the coil if it fails testing, then clear and re-test.

FAQ

Quick answers

Is it safe to drive with P2316?+
For short distances, yes, but a dead coil causes a misfire that can overheat and damage the catalytic converter. Repair it promptly, especially if the light is flashing.
Can I just clear P2316?+
It returns quickly unless the coil or its control circuit is repaired.
