: If sensors and throttle body appear functional, inspect the purge solenoid valve for internal leaks or mechanical failure. Reset and Test

than the computer expects, you likely have a sensor or valve issue. The Component Swap : If cleaning the throttle doesn't work, many owners on the French Car Forum recommend checking the purge valve of the EVAP system. Recalibration
1. Initial Scan:
Inlet Air Pressure Sensor (MAP Sensor):
Inspect the MAP sensor for faults or oil contamination, as it provides the air pressure reading that must "agree" with the throttle position.
- Inspect main fuses in the engine bay and cabin fuse box (especially those for ECU, instrument cluster, and immobiliser).
- Replace any blown fuses and retest.
- Measure battery voltage: healthy battery should be ~12.4–12.7V at rest and >13.5V when cranking/charging.
