THROTTLE BODY ASSEMBLY
Operation Overview
Mounted to the cylinder head, the dual throttle body (Item
1) assembly provides the proper air/fuel ratio needed for
engine operation.
The throttle body assembly also includes the Electronic
Throttle Control and Idle Air Control.
Throttle Body Service
The throttle body assembly is a non-serviceable
component. However, the fuel rail and fuel injectors can
be serviced separately (see “Fuel Injectors”). The
Manifold Air Quality Sensor (MAQS) attached to the end
of the throttle body is non-serviceable. If the sensor is
faulty, the entire throttle body assembly must be
replaced. Refer to “Throttle Body Removal” procedure.
Throttle Body Removal
1. Remove the cargo box assembly (See Cargo Box
Assembly Removal, page 5.21).
2. Be sure the engine has cooled enough to work on.
3. Loosen the hose clamps (Item 1) retaining the intake
plenum (Item 2) to the throttle body.

plenum.
5. Remove the driver’s seat and disconnect the
negative battery cable.
6. Disconnect the wire harness from the ETC (Item 4)
and the TMAP (Item 5) located on the ends of the
