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.
Symptoms
- Check engine light is on
- Idle too high or too low
- Engine stalls or nearly stalls when coming to a stop
- Surging idle
Common causes
- most common: Dirty or carboned-up throttle body
- common: Vacuum leak in the intake or PCV system
- common: Faulty idle air control (IAC) valve
- less common: Faulty throttle position sensor
How to fix it

| Find and repair vacuum leaks with a smoke test | Yes | $10–100 |
