I have a 2005 Volkswagen beetle. Sometimes the car will turn

Customer Question

I have a 2005 Volkswagen beetle. Sometimes the car will turn over but no start. Sometimes it will take 10 minutes, sometimes up to 30 minutes before te car will finally start. Sometimes the car acts like it wants to die when slowing down or going around a corner. Have taken it to the shop, nothing shows up on the scanner. I thought it was the fuel pump at first but the pressure is fine. The car will not act up while at the shop of course.

Hello, Welcome to Just Answer.

This behavior is usually caused by the crank sensor that over heated and is now giving a weak signal to the ECM. (Engine Control Module) This will not cause a fault code as the ECM is still receiving the signal but it is too weak for the ECM to receive a proper reading. I would suggest replacing the crank shaft sensor.

Greetings,

Martin.

Is there a test i can run to determine if the sensor is bad?

Hi,

Yes if you have a VAC-COM scanner tool you can test the signal strenth
