Monitor Description

When the intake manifold pressure measured after engine start drops by less than 3 kPa [0.44 psi] compared to the intake manifold pressure (atmospheric pressure) measured before engine start, the ECM interprets this as a malfunction of the No. 3 turbo pressure sensor and stores DTC P0105-2A.
