It happened again this evening. Same error.
I am glad that I kept my coding gear with me and after resetting the error, car started.
One symptom of crankshaft sensor failure is not charging the battery when car is running. (hope somebody can explain the reason for it)
And in depth of code reading revealed that on 2 ocassions my battery voltage dropped down to 10.6 volt.
Awaiting sensor delivery.
Away for 4 weeks. PM only if its urgent.
