Chevrolet Silverado, Suburban: Engine
Affects Chevrolet Silverado, Suburban · 2001 — about 741 vehicles.
The hazard
On certain vehicles equipped with an 8.1L engine, the crankshaft position sensor may fail. If the sensor operates intermittently, the Service Engine Soon (SES) light may illuminate and the vehicle may run rough. In addition, the engine may stall, and if so, may re-start immediately or after a cool-down period. If the sensor becomes inoperable permanently, the engine will quit running and will not re-start. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will replace the crankshaft position sensor.
