P2413
EGR System Performance
EGR / emissions
Generic OBD-II
Medium
What it means
P2413 means the exhaust gas recirculation (EGR) system isn't flowing the amount of exhaust the PCM expects — either too little or too much. EGR lowers combustion temperature and NOx emissions; when its performance is out of range it's usually carbon-clogged passages or a sticking valve. The engine still runs but may idle rough, ping under load, or hesitate.
Medium
Can I keep driving? Usually yes, but expect possible rough idle, pinging, or hesitation; fix it to restore proper emissions and avoid knock-related wear.
Common symptoms
What you'll notice
- Check-engine light on
- Rough idle or occasional stalling
- Pinging/knock under load
- Hesitation or slight power loss
- May fail an emissions test
Common causes
Most likely first
- Carbon-clogged EGR passages or valveLikely
- Sticking or faulty EGR valveCommon
- Faulty EGR position or temperature sensorCommon
- Vacuum leak or faulty EGR control solenoidLess often
- Wiring or connector fault at the EGR valveLess often
How to diagnose & fix
Work through it in order
- Inspect and clean carbon from the EGR valve and its passages.
- Test EGR valve operation and its position/temperature feedback.
- Check the EGR control solenoid, vacuum lines, and wiring.
- Replace a stuck or failed EGR valve if cleaning doesn't restore flow.
- Clear the code and confirm proper EGR flow on a road test.
FAQ
Quick answers
Is it safe to drive with P2413?+
Generally yes for short trips, but poor EGR flow can cause knock and rough running. Have it cleaned or repaired soon.
Can I just clear P2413?+
It returns once the EGR monitor runs again unless the flow problem is fixed.
