High altitude operation of a ryi2200 generator (5000 ft)

P0087 (flashing code 227) shared sump low pressure fault (for pump without pressure supply)
The main fault symptoms
• Engine severe vibration.
• idling unstable
• Output Fall
• exhaust smoke
• It may be too large output
P0088 (flashing code 118) shared the tank pressure is abnormally high (first or second stage)
The main fault symptoms
• Engine severe vibration
• idle instability
• Output Fall
• channeling gas engine failure
• exhaust smoke
• It may be too large output
P0089 (flashing code 151) shared the tank pressure failure (for pump pressure supply is too large)
The main fault symptoms
• Engine severe vibration
• idle instability
• Output Fall
• channeling gas engine failure
• exhaust smoke
• It may be too large output
P0090 (flashing code 247) SCV drive system open, + B short circuit or shorted to ground
The main fault symptoms
• Depending on the open / short situations, there may be an engine stall and / or launch
Machine channeling gas.
• exhaust smoke
• Output is too large
P0107 (flashing code 71) atmospheric pressure sensor circuit input low (open or shorted to ground)
The main fault symptoms
Due to spare the equivalent altitude 2000 m (6562 ft)
• exhaust smoke at high altitude.
• insufficient output at low altitude
P0108 (flashing code 71) atmospheric pressure sensor circuit input high (+ 5V shorted)
The main fault symptoms
Due to spare the equivalent altitude 2000 m (6562 ft)
• The high altitude exhaust smoke
• lack of low altitude output
P0112 (flashing code 22) intake air temperature sensor fault (low voltage fault, earth fault, short circuit)
The main fault symptoms
• When cold starting, may exhaust white smoke.
