: Replacing the solenoid valve (located beneath the air filter box toward the rear of the engine) has been reported to resolve the issue permanently.
Use a hand vacuum pump to see if the valve holds vacuum when powered off. If it leaks, it's faulty.
To save you time and money, here is a streamlined summary of the most likely fixes for the P306D code. The table below ranks the common solutions based on their likelihood of solving the problem and the difficulty involved.
Since I am an AI, I have generated this report based on the standard repair procedures for this specific fault code. You can use this text to understand what was likely done to fix the vehicle or to fill out your own service documentation.
If the injector failed the resistance test, replace it. Crucial Step: Modern Peugeot diesel and petrol injectors feature an alphanumeric calibration code printed on top. You must program this code into the engine ECU using a diagnostic tool so the computer knows the exact flow rate of the new component.
Swap out the faulty EVAP purge valve line or the entire charcoal canister assembly. For many owners, installing a functional replacement EVAP valve solves the recurring P306D light permanently. Step 3: Clean or Replace the MAP Sensors
Gently wipe away all dark carbon ring accumulations around the valve seating edge. Do not force the butterfly valve open aggressively by hand to prevent damaging the internal plastic drive gears. Step 4: Reset Adaptions and Clear Fault Codes
Based on common issues experienced by Peugeot owners, here is the most effective approach to fixing the P306D error, especially on 1.6 PureTech engines. 1. Locate and Inspect the EVAP Purge Valve
Connect an OBD2 scanner (preferably Diagbox, Peugeot's factory software) and navigate to the live data stream. Monitor the against the Actual Fuel Pressure .
If the valve seems fine, the coherence error might stem from a vacuum leak somewhere in the intake system, which makes the air/fuel ratio unstable.
