Your knock sensor is located Under the hood, center, front engine area, below intake
manifold, mounted on block.
A defective knock sensor may cause engine detonation or reduced
spark advance and fuel economy. When a knock sensor is removed and
replaced, the sensor must be tightened to its specified torque. If the
knock sensor is installed tighter than it should be, it may become too
sensitive and provide an excessively high voltage signal, resulting in
more spark ****** than required. When the knock sensor is installed
looser than it should be, the knock sensor signal will be lower than
normal, resulting in engine detonation.
To replace the knock sensor:
- Disconnect the knock sensor wiring connector.
- Then, unscrew the sensor.
- Remove the knock sensor.
- Reverse the procedures to install the part.
