Flash Codes List and DTCs
P0087 (flash code 227) fuel rail pressure is too low (for a pump without pressure applied)
Main symptoms
• Strong engine vibration.
• Unstable idling
• Output power drop
Exhaust smoke
• There may be too much smoke.
P0088 (flash code 118) fuel rail pressure too high
Main symptoms
• Strong engine vibration
• idle unstable
• Output power drop
• failure to pump the gas engine
Exhaust smoke
• May be too big a way out.
P0089 (flash code 151) fuel rail pressure regulator faulty
Main symptoms
• Strong engine vibration
• idle unstable
• Output power drop
Exhaust smoke
• May be too big a way out.
P0090 (flash code 247) SCV open or short of fuel pressure regulator
Main symptoms
• Depending on the open / short situations, the engine may stop and / or start
Exhaust smoke
• Smoke output too large
P0107 (flash code 71) Atmospheric pressure sensor input signal low (opened or shorted to ground)
Main symptoms
Due to a spare equivalent height of 2000 m (6562 ft)
• exhaust smoke at high altitude.
• low power at low altitude
P0108 (flash code 71) Atmospheric pressure sensor input high (+ 5 V short-circuited)
Main symptoms
Due to a spare equivalent height of 2000 m (6562 ft)
• High exhaust smoke
• lack of power at low altitude
P0112 (flash code 22) intake air temperature sensor malfunction (low voltage error, ground fault, short circuit)
Main symptoms
• Cold start may emit white smoke.
P0113 (flash code 22) intake air temperature sensor fault (high supply voltage circuit fault)
Main symptoms
• Cold start may emit white smoke.
P0117 (flash code 23) engine coolant temperature sensor malfunction (low voltage error, ground fault, short circuit)
Main symptoms
• At normal temperature: smoke may be emitted,
• When the ambient temperature is low when idling: unstable idle may be, engine start is difficult
P0118 (flash code 23) The engine coolant temperature sensor provides overestimated data (closed to positive or short circuit)
Main symptoms
• At normal temperature: smoke may be emitted,
• At low temperatures during idle time: there may be an unstable idle,
P0182 (flash code 211) Malfunctioning fuel temperature sensor (low voltage faults shorted to ground)
Main symptoms
Impact on performance.
