On Sat as I was driving my van just stopped running while at a stop light. I started right back up and drove about a block to the next light where it again died. However this time it took a few tries and minutes before it would restart and this time the engine light remained on. So I drove right to my local kia dealership and they ran a code check and it showed a code which was crank shaft sensor. I was told by the dealership that a van with 140,000 miles and over 9 years old can have this issue.
1. Is this true, is that kind of miles and age about when this sensor would begin to fail?
2. What does this sensor do and why does the engine shut off?
They told me that to repair it was a bit expensive due to it's location. They asked me if I have had my timing belt replaced. I told them I have an appointment with then in 2 weeks to get that belt changed. They suggested that if possible don't drive the van for the next two weeks and have all the work done then as it would save me money. They said to replace both timing belt and serpentine belt and the Crank Shaft sensor would run me about $700.
3. So does that seem like a fair price for all the labor and parts involved to do such work?
