System of on-board diagnosis (EOBD)
This diagnostic system informs the driver when the depollution equipment is no longer fulfilling its role.
Faults in the system causing polluting emissions are memorised in the injection ECU.
The "engine diagnosis" warning lamp, in addition to its usual functions, signals any faults in the depollution function (EOBD).
NOTE : EOBD : European On Board Diagnosis, for diagnosis of depollution equipment.
The on-board diagnosis system monitors :
- Combustion misfiring
- Efficiency of the catalytic converter
- Deterioration of the oxygen sensors
EOBD requires the installing of an oxygen sensor (downstream of the catalytic converter).
