REMOVAL AND INSTALLATION

Throttle Body

Removal

  1. Disconnect battery ground cable (14301).

  1. Remove air cleaner outlet tube.

  1. NOTE: Some coolant will be lost when throttle body (9E926) is removed.

    Partially drain radiator (8005).

  1. Remove accelerator control splash shield (9E766) from throttle body.

  1.  CAUTION: When disconnecting throttle cable from ball stud, use a screwdriver or similar tool close to the stud and pry slowly. Pulling by hand may damage the cable.

    Disconnect throttle linkage at throttle ball. Disconnect C6 (5.8L only) transmission linkage from throttle body.

  1. Disconnect throttle position sensor and idle air control valve wiring connectors.

  1. Remove engine coolant hose connectors and vacuum lines as necessary.

  1. Remove four throttle body bolts.

  1. Carefully separate throttle body from upper intake manifold (9424).

  1. Remove and discard gasket between throttle body and upper intake manifold.

Installation

  1. NOTE: If scraping is necessary, be careful not to damage gasket surfaces of throttle body and intake manifolds, or allow gasket material to drop into intake manifold.

    Make sure that both throttle body and upper intake manifold gasket surfaces are clean.

  1. Install throttle body gasket on the four studs of the upper intake manifold.

  1. Install throttle body to upper intake manifold.

  1. Secure throttle body to upper intake manifold with four retaining bolts. Tighten to 16-24 Nm (12-18 lb-ft).

  1. Reinstall engine coolant hoses and vacuum connections as necessary.

  1. Connect air control valve and throttle position (TP) sensor electrical connectors.

  1. Connect throttle cable and transmission linkage to throttle body.

  1. Install accelerator control splash shield on the throttle body.

  1. Replace coolant in the radiator as necessary.

  1. Install air cleaner outlet tube. Refer to Section 03-12.

  1. NOTE: When the battery (10655) has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

    Reconnect battery ground cable.
