Target Idle Not Reached
1997 Plymouth Breeze L4-2.0L VIN CSECTION Target Idle Not Reached
Name of Code:
Target Idle Not Reached
When Monitored:
With the engine idling and in Drive if automatic. There must not be a MAP sensor trouble code or a throttle position sensor trouble code.
Set Condition:
Engine idle is not within 200 rpm above or 100 rpm below target idle for 14 seconds. Three separate failures are required to set a bad trip. Two bad trips are required to set code.
Theory of Operation:
The Idle Air Control (IAC) motor is used by the PCM to help regulate idle speed. The motor controls the amount of air allowed to bypass the throttle blade. The PCM controls the motor using four driver circuits to position the stepper motor.
Possible Causes:
- Driver circuit shorted to ground
- Driver circuit shorted to battery
- Driver circuits shorted together
- Failed PCM
- Shorted IAC motor
- Carbon deposits
- Driver circuit open
- Connector terminals
- Connector wires
- Large vacuum leak
- Throttle misadjusted (min. airflow RPM wrong)
- Throttle not closing reliably

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
