P2030Fuel Fired Heater Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2030 is the functional check of a fuel fired heater: it is wired and commanded, but does not ignite, keep its flame or deliver the heat expected. Hino uses the code on 2011–2014 conventional trucks with the J08 engine, where a burner heats the exhaust for particulate filter regeneration. Its burner control unit confirms ignition through a flame temperature sensor and logs P2030 as burner misfire; campaign SCB-006-15 reprogrammed the unit because a flame not touching the sensor was read as a misfire, and SB-15-032 revised the troubleshooting. In cabin and coolant heaters the same idea appears as Webasto's start, flame-out and overheat faults. CARB lets each maker define the monitor for such devices. Typical causes are fuel starvation, a worn glow pin, blocked combustion air or a contaminated flame sensor.
- What you may notice
- Heater fails to start or goes out
- White smoke or fuel smell from the heater exhaust
- Burner-assisted filter regeneration does not complete
- Likely causes
- LikelyFuel starvation at the heater (dosing pump, filter, line)
- PossibleWorn glow pin or contaminated flame sensor
- PossibleCombustion air inlet or exhaust of the heater blocked, sooted chamber
- RareControl unit software misjudging the flame (update on some models)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
