General
Refer to the VRSCA Electrical Diagnostic Manual for information on the function and testing of the manifold absolute pressure sensor (MAP).
Removal
1. Remove airbox and air filter. See 1.4 Airbox and air filter.
Caution! If airbox is not to be reinstalled immediately, cover throttle body intakes with tape to prevent contaminates/ objects from falling down the throttle bores. Do not use shop rags or objects that could damage the throttle body butterflies.
2. Cover air intakes to prevent debris from entering cylinders.
Warning! To protect against shock and accidental start-up of vehicle, disconnect the negative battery cable before proceeding. Inadequate safety precautions could result in death or serious injury.
3. Disconnect negative battery cable.
4. See Figure 9-13. Remove bolt (1) securing MAP sensor bracket (2) to front cylinder.
