What is an Ignition Knock (Detonation) Sensor Harness?

An Ignition Knock (Detonation) Sensor Harness is a specialized wiring harness used as part of an engine's ignition system. It connects the ignition knock (detonation) sensor to the engine's powertrain control module, allowing the module to monitor the level of engine knock (detonation) and adjust the timing of the spark plugs accordingly.

What is the purpose of an Ignition Knock (Detonation) Sensor Harness?

The purpose of an Ignition Knock (Detonation) Sensor Harness is to provide a reliable connection between the knock (detonation) sensor and the powertrain control module. This ensures that the module can accurately monitor the level of engine knock (detonation) and adjust the timing of the spark plugs accordingly.

How do I determine if my Ignition Knock (Detonation) Sensor Harness is faulty?

If your Ignition Knock (Detonation) Sensor Harness is faulty, you will likely notice that your engine is running rough, or that it is not running as efficiently as it should be. Additionally, you may notice that the engine is producing higher-than-normal levels of exhaust emissions.

Can a faulty Ignition Knock (Detonation) Sensor Harness cause damage to my engine?

Yes, a faulty Ignition Knock (Detonation) Sensor Harness can cause damage to your engine, as it can lead to incorrect timing of the spark plugs and thus higher levels of engine knock (detonation) than normal. This can result in engine damage, such as worn out pistons, valves and bearings.

How do I replace an Ignition Knock (Detonation) Sensor Harness?

Replacing an Ignition Knock (Detonation) Sensor Harness is relatively straightforward. To replace it, you should:

  1. Disconnect the negative battery cable.
  2. Locate and remove the old Ignition Knock (Detonation
  3. Sensor Harness.
  4. Connect the new Ignition Knock (Detonation
  5. Sensor Harness.
  6. Re-connect the negative battery cable.


How often should I inspect my Ignition Knock (Detonation) Sensor Harness?

You should inspect your Ignition Knock (Detonation) Sensor Harness at least once a year, and more often if you notice any signs of wear or damage. If you notice any signs of wear or damage, replace the harness as soon as possible to avoid further damage to your engine.
