The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance. Communicating these specific symptoms to your technician can save diagnostic time.

    One day, the check engine light went on. Before I could get it to a shop, it died at a stop sign. I had it towed to a shop, and they diagnosed it as a bad crank position sensor. I got it fixed for $250. It's been running great for over a year since then.

    My car was suddenly stop on the road without any notice, I tried to start but it didn't work, and I cannot pull over my car to the sideway. After 45 mins, I started my car and it worked, and the Check Engine light was on when I re-started my car. However; it stopped again after 10 mins driving. I took it to the dearler, they replaced the crankshaft position sensor.
