P2110 on Dodge by model: symptoms, diagnosis and fix
Darts across all engine options experience random stalling at idle, particularly when coming to a stop or sitting at traffic lights. The issue stems from a combination of electronic throttle body carbon buildup and PCM software calibration problems. The 2.0L and 2.4L engines are most commonly affected. Several TSBs have been issued addressing idle quality.
Common Symptoms
- Engine stalls when coming to a stop
- Rough or fluctuating idle RPM
- Engine dies at traffic lights or in drive-through
- Momentary loss of power steering when engine stalls
- Check engine light may or may not illuminate
How to Fix
Start with a throttle body cleaning using CRC throttle body cleaner — remove the intake hose and clean the butterfly valve and bore. Then visit a dealer for the latest PCM flash update (TSB 18-034-14 REV.B or newer). If stalling persists after both steps, replace the electronic throttle body assembly (Mopar 04891585AC for 2.4L). Perform idle relearn after any throttle body service.

It is usually a reaction to another underlying throttle fault rather than the root cause itself, so other related codes are typically present. Because power is limited and acceleration is restricted, the car may be unsafe to drive in traffic and should be diagnosed promptly. On Dodge it is documented across 1 model: Dart.
