XJ8 Knock Sensor

The knock sensor on a 2003 Honda CRV is located on the engine block. Specifically, it is located under the intake manifold, which means it can be difficult to access. Here are the steps to locate and replace the knock sensor on a 2003 Honda CRV:

1. Disconnect the negative battery cable to prevent electrical shock.
2. Remove the intake manifold. This involves removing several bolts and electrical connections.
3. Locate the knock sensor, which is located near the rear of the engine block, under the intake manifold.
4. Disconnect the electrical connector from the sensor.
5. Remove the sensor from the engine block. This may require a special tool, depending on the specific design of the sensor.
6. Install the new knock sensor, making sure it is properly aligned and tightened to the correct torque specification.
7. Reconnect the electrical connector to the sensor.
8. Reinstall the intake manifold, making sure all bolts and electrical connections are properly secured.
9. Reconnect the negative battery cable.

Note that if you are not experienced with working on engines or are unsure of how to proceed, it may be best to seek the assistance of a qualified mechanic to replace the knock sensor on your 2003 Honda CRV.

I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.
