Knock Sensor: Service and Repair
2006 Dodge Magnum SRT-8 V8-6.1L VIN 3SECTION Service and Repair
SENSOR-KNOCK
REMOVAL
Two knock sensors (1) are used. Each sensor is bolted to the outside of cylinder block below the exhaust manifold (3).
1. Raise vehicle.
2. Remove heat shield (1) from knock sensor. Shield snaps to sensor.
3. Disconnect knock sensor electrical connector (5).
4. Remove sensor mounting bolt (2). Note foam strip on bolt threads. This foam is used only to retain the bolts to sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
5. Remove sensor from engine.
INSTALLATION
1. Thoroughly clean knock sensor mounting hole.
2. Install sensor (1) onto cylinder block.
NOTE:
- Over or under tightening the sensor mounting bolts will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensors. The torque for the knock senor bolt is relatively light for an 8mm bolt.
- Note foam strip on bolt threads. This foam is used only to retain the bolts to sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
3. Install and tighten mounting bolt (2).
4. Install electrical connector (5) to sensor.
5. Install heat shield (1) to sensor (shield snaps on).

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
