Here's how you can find the right diagram:
1. Identify your engine: Look for a sticker or plate on the engine block, usually near the valve cover. This will have information like the engine size and code (e.g., 2.5L, V6, etc.).
2. Use online resources: Search for "1989 Chevrolet Celebrity [engine size] crank sensor diagram" on Google Images or other online resources like AutoZone, AllData, or Chilton.
General information about crank sensors:
* Function: The crank sensor sends pulses to the engine control unit (ECU) based on the crankshaft's rotation. This information is used to determine the timing of ignition and fuel injection.
* Location: The crank sensor is usually mounted near the crankshaft pulley, often on the bellhousing or in the timing cover.
* Appearance: The crank sensor is typically a small, cylindrical device with a wire harness.
If you can't find a specific diagram, consider these general points:
* Follow the wiring harness: The crank sensor wire harness will lead to the ECU.
* Look for a magnetic pickup: The crank sensor will likely have a magnetic pickup that senses the crankshaft's rotation.
Remember: Always consult the owner's manual or a repair manual for your specific vehicle before attempting any repairs.
