P24E0: Reductant Purge Control Valve B Stuck Closed
Standardized SAE J2012 code · P24xx — Auxiliary emission controls
What does P24E0 mean?
Same as P24DF with valve B stuck closed - AdBlue cannot be cleared at shutdown, risk of crystallisation in injector and lines.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Check engine light or NOx warning on
- AdBlue/DEF level or quality warning
- Possible no-start countdown after ignore period
- Failed emissions inspection (NOx)
Common causes
- High Valve stuck closed
- Low Carbon or debris buildup preventing free movement
- Low Component wear with age - mechanical play
Likelihood is a general estimate across vehicles; your make and model may differ.
