2001 Chevrolet Chevy K Silverado Crankshaft Position Sensor Engine Stall

Download Models: 2001 Chevrolet Silverado, Suburban 2001 GMC Sierra, Yukon XL Equipped with 8.1L V8 (RPO L18 – VIN G) Engine. Condition General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2001 model year Chevrolet Silverado, Suburban; GMC Sierra and Yukon XL model vehicles, equipped with an 8.1L V8 (RPO L18 – VIN G) engine. Some of these vehicles have a condition in which the crankshaft position sensor can fail intermittently or permanently. If the sensor fails 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 fails permanently, the engine will quit running and will not re-start. Correction Dealers are to replace the crankshaft position sensor. Vehicles Involved Involved are certain 2001 model year Chevrolet Silverado, Suburban; GMC Sierra and Yukon XL model vehicles, equipped with an 8.1L V8 (RPO L18 – VIN G) engine and built within these VIN breakpoints: Subject: 06083 — Crankshaft Position Sensor Engine Stall Models: 2001 Chevrolet Silverado, Suburban 2001 GMC Sierra, Yukon XL Equipped with 8.1L V8 (RPO L18 – VIN G) Engine Year Division Model From Through 2001 Chevrolet Silverado iE100004 1E200999 1F100006 1F116767 1M100002 1M103668 1Z100010 1Z100042 2001 Chevrolet Suburban 1G100001 1G174359 1J100010 1J100058 2001 GMC Sierra 1E100003 1E2012022 1F100004 1F113912 1M100023 1M103669 1Z100013 1Z100026.… Read More

1997 – 2001 Infiniti Q45 ENGINE WILL NOT START

Download 2000 – 2001 I30 (CA33) 1999 I30 (CA32) 1999.5 – 2001 QX4 (JR50) 1997 – 2001 Q45 (FY33) 2000 – 2001 G20 (P11) APPLIED VINS: All APPLIED DATES: Start of production SERVICE INFORMATION This bulletin describes and introduces new features of the Infiniti Vehicle Immobilizer System/Nissan Anti-Theft System (IVIS/NATS). The system is standard equipment on each of the applied vehicles listed above. The IVIS/NATS will not allow the engine to start without the use of a registered ignition key. If a vehicle will not start and the Security lamp is on solid, it may be because the ignition keys were not properly registered into the vehicle’s NATS IMMU (Immobilizer control unit). In this case, there will be a “DIFFERENCE OF KEY” code stored in the NATS IMMU. When the NATS ignition key, IMMU, or ECM (ECCS control unit) are replaced, C/U initialization is necessary. It is also necessary when registering keys and as part of many NATS Service Manual diagnostic procedures.… Read More
