Clean the throttle body with specialized cleaner. If the fault persists, the motorized unit may need replacement and recalibration via a diagnostic tool. Inlet Air Pressure (MAP) Sensor Fault The Issue:
A different angle was reported on a Peugeot 3008 forum where the code was described as an "adaptive recalibration of the throttle housing out of tolerance." In these cases, a simple cleaning is not enough. If all mechanical checks pass, the issue may be a failing throttle body actuator requiring complete replacement. p306d peugeot fixed
Note: If you find fine metal shavings (silver glitter), your high-pressure fuel pump is failing internally and shedding metal. The entire fuel system will require flushing. Clean the throttle body with specialized cleaner
If new parts are unavailable, some users have found success with tested used parts from similar turbocharged models, such as the RCZ. 3. Clean or Replace the Throttle Body If all mechanical checks pass, the issue may
: If the purge valve doesn't fix it, the entire EVAP canister itself may be faulty or broken, causing pressure discrepancies. Fuel Quality
The motorized throttle valve can accumulate carbon oil sludge or suffer from subtle gear wear over time. At lower speeds, where minute changes in the throttle plate angle are critical, a sticky mechanism prevents smooth operation. The sensor reads an expected position, but the physical airflow restricts or surges out of alignment. 3. Faulty or Contaminated MAP Sensor
