P2313

Ignition Coil E Primary Control Circuit High

Q: Is it safe to drive with P2313?

Only briefly. A steady misfire sends raw fuel into the exhaust and can overheat the converter — a flashing light means stop driving soon.

Q: Can I just clear P2313?

It returns quickly because the ECM keeps monitoring the coil circuit until the coil or wiring is repaired.

Ignition / misfire Generic OBD-II Medium

What it means

P2313 means the ECM has detected high voltage — usually an open or high-resistance circuit — on the primary control for ignition coil E. That cylinder can misfire, causing a rough idle and lost power, and a sustained misfire can damage the catalytic converter, so it should be addressed promptly.

Medium

Can I keep driving? Drivable but expect a misfire on that cylinder — if the check-engine light flashes, drive as little as possible to protect the catalytic converter.

Common symptoms

What you'll notice

Check-engine light on (may flash during an active misfire)
Rough idle, stumble, or hesitation
Loss of power on acceleration
Slightly increased fuel consumption

Common causes

Most likely first

Faulty ignition coil E or an open in its primary windingLikely
Open or high-resistance in the coil control (driver) circuitCommon
Corroded or loose coil connectorCommon
Broken or chafed harness near the coilLess often
Failed coil driver inside the ECM/ignition moduleLess often

How to diagnose & fix

Work through it in order

Read freeze-frame data and note which cylinder coil E feeds.
Inspect the coil connector and control wire for an open or corrosion.
Swap coil E with a known-good coil and see if the fault follows the coil.
Check the control wire back to the ECM for an open circuit.
Replace the coil if faulty, then clear and confirm the misfire is gone.
