Removing intake manifold pressure sensor

Information

Specifications for wrench sizes (a/f specifications) for screw heads are described as follows:

- Torx screws: (E.) for external Torx, (T.) for internal Torx.

- Hexagon-head bolts (internal and external hexagon): Wrench size (a/f)

1. Unclip hose from the recirculating air valve on cylinder bank 4-6 and set it aside.
2. Release and pull off cable plug on intake manifold pressure sensor.
3. Unscrew one internal Torx screw (M6 x 15, T30) -1-.
