Salut Mec !
à première vu, le code erreur 1+2+4=7 est le capteur d'ouverture de papillon qui merde
Soit défaillant,
Soit débranché / faux contact.
Pour information & Bible :
Note: OOOO all 4 lamps on, XXXX all 4 lamps off
OOOO Engine will not start - Check for disconnected control unit ground connector. Also check for a loose connection at the ECU main relay resistor. Possible faulty ECU.
OOOO Engine will not start - Check for a short circuit in the combination meter or warning light wire. Also check for a disconnected control unit ground wire. Possible faulty ECU.
OOOX System does not operate - Faulty ECU
OOXO System does not operate - Faulty ECU
OOXX Fuel-fouled spark plugs, engine stalls frequently - Check for a disconnected MAP sensor coupler or an open circuit in the MAP sensor wire. Also faulty MAP sensor.
OXOO System does not operate - Faulty ECU.
OXOX Hesitation, fuel-fouled spark plugs or engine stalls frequently - Check for disconnected MAP sensor vacuum hose.
OXXO High idle speed during warm-up, continued high or hard starting at low temperature - Check for disconnected coolant temperature sensor connector or an open circuit in the coolant temperature sensor wire. Also faulty Coolant Temperature sensor.
OXXX Poor engine response when opening the throttle rapidly, high idle speed or engine does not rev-up when cold - Check for a disconnected throttle angle sensor connector. Also check for an open circuit in the throttle angle sensor wire. Also faulty throttle angle sensor.
XOOO Engine dose not rev-up, high idle speed or erratic idling - Check for a short or open in the crank angle sensor wire. Spark plug wires interfering with the crank angle sensor wire. Also faulty crank angle sensor.
XOOX Same as above (XOOO)
XOXO High idle speed or erratic idling when very cold - Check for disconnected intake air temperature sensor or an open circuit in the intake air temperature sensor wire. Also faulty Intake Air Temperature sensor.
XOXX Continued high idle speed - Check for a disconnected idle mixture adjuster sensor coupler or an open circuit in the idle mixture adjuster sensor wire. Also faulty Idle Mixture Adjuster sensor.
XXOO System does not operate at all - Faulty ECU
XXOX Poor acceleration at high altitude when cold - Check for a disconnected atmospheric pressure sensor coupler or an open circuit in the atmospheric pressure sensor wire. Also faulty Atmospheric Pressure Sensor.
XXXO System does not operate at all - Faulty ECU
XXXX Same as above (XXXO)
