Code familyIgnition or misfire fault

Short trips onlyDrive it only if you have to, gently and not far. Get it fixed right away.

Check this first

If the light is flashing, stop driving. Otherwise start with spark plugs and coils.

What usually fixes it

In the order a good shop checks them. Typical total: $165–$3,488 at $130 an hour.

  1. Spark plugs

    $196–$404

    Worn plugs cause most misfires.

  2. Ignition coil

    $165–$595

    Coils fail one at a time, often when hot.

  3. Fuel or compression fault

    $372–$3,488

    If ignition parts are good, the cylinder isn't getting fuel or holding pressure.

This is the advice for this family of codes – Drive DTC doesn't have advice written for P0345 on its own yet.

Code titles are the generic SAE definitions. Prices are typical US parts and labor for a common car or light truck – a guide for judging a quote, not a quote. Always confirm a repair against the vehicle in front of you.

A stored code is a headline, not the story. The vehicle also holds the conditions from the moment the code set, how close each part is to the limit it fails at, what the fuel trims are doing, and whether the fault is still happening. Drive DTC reads all of it with a USB adapter and a Windows PC – read-only by design.
