The Engine Control Unit (ECU) constantly cross-references data from the Manifold Absolute Pressure (MAP) sensor against the physical angle of the electronic throttle body.

In simpler terms, the ECU (Engine Control Unit) expects a certain amount of air pressure (read by the MAP sensor) to correspond with the position of the electric throttle body/air mixer. When these two readings do not match, the system throws this coherence error. p306d peugeot
