Dirt or oil on the throttle body sensor or the MAP (Manifold Absolute Pressure) sensor can cause mismatched readings.

Regular Peugeot servicing (including a minor service costing £250-400) can help prevent many of these issues from developing in the first place.
Introduced in 1999, this common-rail diesel engine replaced the older units, offering 90 hp with improved fuel economy and refinement. Details on these various engine configurations are documented in archives like those on Scribd . Common "P306D" Technical Issues
: The dashboard warning light often pops up specifically during idling, when decelerating, or when stopping at traffic lights.
The motorized throttle housing regulates the air mix. Heavy carbon sludge and soot can physically block the butterfly valve from closing or opening smoothly. When the valve's electronic position sensor reports one angle but the air pressure says otherwise, P306D is generated. 4. Vacuum Leaks
Poor acceleration or jerking motion during driving.
The P306D-22 code on a Peugeot, often accompanied by a "22" suffix (P306D-22), is typically defined as:.
If you have a 1.6 petrol engine, inspect the solenoid valve located near the rear of the engine under the intake manifold.
The Engine Control Unit (ECU) constantly compares the angle of the electronic throttle butterfly valve with the readings from the Manifold Absolute Pressure (MAP) sensor. When the air pressure entering the engine does not match what the ECU expects for a given throttle position, it triggers this "coherence" fault.

The Manifold Absolute Pressure (MAP) sensor might be providing incorrect data to the ECU.
On models like the 508 or 3008, the solenoid valve (often part number V759557380
In the modern PSA (Peugeot/Citroën/DS) ecosystem, P306D is a manufacturer-specific code rather than a physical car model. It is most commonly reported in 1.6 PureTech petrol engines found in newer Peugeots. P306D-22 coherence problem - French Car Forum
Additional fuel vapors enter the manifold when they shouldn't, raising the pressure and throwing off the sensor coherence. 2. False Readings from the MAP Sensor
