P1294 Code: Target Idle Not Reached

🟢 Low severity · drivable

The car will usually run, but the idle may be too high, too low, or unsteady, so get it checked.

What P1294 means

The engine computer commands a target idle speed, but the engine never reaches it. P1294 means the computer couldn't bring the idle where it wanted within a set time. This code is most often reported on Chrysler, Dodge, and Jeep vehicles, and it usually comes down to a dirty throttle body, a vacuum leak, or an idle control problem.

Idle too high or too low
Engine stalls or nearly stalls when coming to a stop
