At least this was my experience with bad sensor, though it may cause other conditions as well. My bad sensor was a Bosch, and I THINK OEM, (WHICH BECAME BAD AT 110,000 MILES) because it said on it that it was made in Germany, while in more recent years. most Bosch examples I have seen say that they were made in Romania. Having this sensor die on you, especially when you are many miles into the most remote areas possible, does not lend itself to your personal security. DOES ANYONE KNOW, IN GENERAL, THE LIFE EXPECTANCY OF THESE BOSCH CRANKSHAFT POSITION SENSORS? AM I CORRECT, IN THINKING THAT THEY MAY LAST AROUND 100,000 MILES, IF MY ANALYSIS IS CORRECT, OR AM I WAY OFF WITH WHAT I THINK IS AN EDUCATED GUESS? PLEASE SHARE WITH ME, AND OTHER READERS, YOUR EXPERIENCES WITH FAULTY BOSCH CRANKSHAFT POSITION SENSORS.
