The National Highway Traffic Safety Administration (NHTSA) is directing the recall of 11,974 2001-model-year heavy duty pickups built by General Motors to fix faulty crankshaft position sensors, under NHTSA campaign ID number 07V521000.Only Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 trucks with 8.1-liter Vortec V8 big block gasoline engines are impacted by the recall.According to NHTSA's website, the crankshaft position sensor can operate intermittently or fail completely. If the sensor operates intermittently, the service engine light may illuminate and cause the vehicle to run rough or stall the engine. The engine can be restarted immediately or after a cool down period. If the sensor fails completely, the engine will not run.GM dealers will replace the crankshaft positioning sensor free of charge when the recall begins in December.Taken from an article in pickup truck.com
I have a 2001 8.1 chevy silverado HD and I am having problems but I have never received a recall; I am afraid to drive on the freeway with this problem(so far I havbe been in the right lane, god forbid I am in the passing lane when it quits. Please help me thank-you JIm
Has anyone had to deal with this yet, My GMC 3500 8.1L is doing exactly what the supposed recall describes. I took it to the dealer and they said my truck VIN didn't qualify. I bought the position sensor does any one know where the sensor is located? I believe it is right behind the starter.Terry_russell
Yes Terry, I was let down on my 3500 Silverado Wed. 10, 2010 in Lakeland,Fl. I had to be towed to the nearest service station that Good Sams chose. They had to replace my crankshaft sensor at a tune of close to $300.00 for the part Plus labor & etc. I never got any recall in the mail on this recall. I guess GM doesn't value anyones life!! I don't know where it is exactly located, but it is about 9" long & about 3/4 of an inch in dia.Gary Howard .
I believe this sensor is located in the engine block near the transmission. I only hope this genuine part is safer & better than the old one!!! I have only 29,000 miles on the engine & the truck has never been run in the Winter. I sometimes wonder why GM took this block off the market after 5 years without explaining why.Gary Howard
