1. Make sure the throttle linkage operates smoothly.
2. Start the engine, disconnect the vacuum hose, check the vacuum with a vacuum gauge and compare with the table data.
Replacement
1. Disconnect the battery from ground.
2. Remove the air duct by loosening the clamps.
3. Disconnect the cable from the damper, remove the cable bracket and move it to the side.
4. If the vehicle is equipped with an automatic transmission, disconnect the transmission throttle cable, remove the bracket and set it aside.
5. Identify and disconnect all vacuum hoses from the throttle body.
6. Disconnect the connector from the housing and unscrew the bolts.
7. Remove the damper housing and gasket. Clean the housing, blow out all channels with compressed air. Do not wipe the damper sensor with solvent.
Installation
1. Installation is carried out in reverse order.
2. Tighten the mounting bolts to the specified torque.
