Where is encoder motor sensor for a 1999 Chevy Suburban?

The 1999 Chevy Suburban's encoder motor sensor, more accurately called the crankshaft position sensor (CKP), is located on the engine block, near the crankshaft pulley. Its exact location will vary slightly depending on the engine (e.g., 5.7L Vortec, 6.5L Diesel).

To find it, you'll need to:

1. Consult a repair manual: A Chilton's or Haynes manual specific to your 1999 Suburban's engine will give you a diagram and precise location. This is the most reliable method.

2. Use an online repair database: Sites like AllDataDIY or Mitchell 1 (subscription required) offer detailed diagrams and repair information.

3. Visual Inspection (with caution): Look near the crankshaft pulley on the engine block. The sensor will typically be a small, cylindrical unit with a single wire connector. Be extremely careful near moving engine parts. Never attempt this with the engine running.

Important Note: The distributor (in older vehicles) contains components that might be incorrectly called an "encoder motor." The 1999 Suburban does *not* use a distributor; it has electronic ignition. The critical sensor for engine position is the crankshaft position sensor (CKP).
