Knock Sensor Replacement. Chevrolet Beretta 1996

For 1990-2009 cars

### Removal Procedure

1. Disconnect the negative battery cable from the battery.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2. Raise the vehicle and suitably support.

Caution: Provide additional support when a vehicle is on a hoist in the following ways:

• | Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

• | Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
3. Disconnect the KS wiring harness connector from the knock sensor.
4. Remove the knock sensor from the engine block.

### Installation Procedure

1. Clean the threads thoroughly. Install the knock sensor into the engine block.

Tighten
Tighten the knock sensor to 16-22 N·m (143-196 lb in).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Connect the KS wiring harness connector to the knock sensor.
3. Lower the vehicle.
4. Connect the negative battery cable to the battery.
