Where is the knock sensor on a 1997 Chevy Tahoe?

The knock sensor location on a 1997 Chevy Tahoe (assuming a Vortec 5.7L or 4.3L engine) varies slightly depending on the exact engine. However, it's generally located on the engine block, near the distributor (if equipped) and close to the cylinder head.

To be certain:

1. Consult your owner's manual: This is the best source for the precise location for your specific Tahoe's engine.

2. Use a repair manual (like Haynes or Chilton): These manuals include detailed diagrams showing the location of all sensors.

3. Look online: Search for "1997 Chevy Tahoe knock sensor location [engine size]" on sites like YouTube or repair forums. Images are very helpful.

Important Note: Before attempting any work on your vehicle's engine, disconnect the negative battery terminal to prevent electrical shorts or damage. If you're not comfortable working on your vehicle's engine, take it to a qualified mechanic.
