When the intake manifold pressure measured after engine start drops by less than 2 kPa(gauge) [15 mmHg(gauge)] compared to the intake manifold pressure (atmospheric pressure) measured before engine start, the ECM interprets this as a malfunction in the manifold absolute pressure sensor and stores DTC P0106.
