Manifold absolute pressure (map) sensor

Refit

1. Clean mating faces of throttle housing and TP sensor.
2. Fit TP sensor to throttle spindle. Ensure that during fitting, the machined flat on the throttle spindle is aligned with the mating portion of the TP sensor.

CAUTION: The TP sensor can be easily damaged during fitting. When pressing the sensor onto the throttle spindle, use fingers only, and only apply pressure to the area shown shaded in the illustration.

3. Rotate TP sensor in an anti-clockwise direction to align fixing holes.

CAUTION: Do not rotate sensor in a clockwise direction, and ensure that it is not rotated beyond its internal stops.

4. Fit TP sensor specification plate.
5. Fit NEW screws and wave washers, and tighten to 1.5 Nm.

CAUTION: Do not exceed specified torque figure.

6. Connect multiplug to TP sensor.
7. Connect brake servo vacuum pipe to inlet manifold.
8. Connect air bypass hose to throttle body.
9. Operate throttle cable cam 2 or 3 times and ensure that full travel to the throttle open and the throttle closed positions is available.
10. Fit air cleaner. See this section.
