P26B3: Fuel Shutoff Valve A Control Circuit Performance/Stuck Off
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P26B3 mean?
The first fuel shutoff valve is commanded on but does not open. Fuel cannot reach the engine via this path.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Valve seized closed by debris
- Medium Solenoid loses force from coil aging
- Low Carbon or debris buildup preventing free movement
