Abstract (en)
[origin: WO0015960A1] A pressure sensor (40) is mounted in an internal combustion engine (1) for determining induction pipe pressure (P) in a connecting line (30) between the induction pipe (5) and the fuel pressure regulator (35). When checking the exhaust gas recirculation valve (20), induction pipe pressure (P) rises. Said change in pressure is safely and reliably recorded independently of actuation of other pneumatic consumers (vacuum power booster).
