Monitor Description

WARNING: This page is about a different car, the 2025 Lexus RX 350, 2024 Lexus RX 350, and 2023 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.

When the intake manifold pressure measured after engine start drops by less than 3 kPa [0.4 psi] compared to the intake manifold pressure (atmospheric pressure) measured before engine start, the ECM interprets this as a malfunction of the No. 1 turbo pressure sensor and stores DTC P0105-2A.
