High sensor Voltage for switch time calculation problem

Question

Hello,

I have fitted CNG kit in my petrol Chevrolet Optra car 7 months back.
Recently the Engine check light was turned on and it goes off by itself and again on.
I tried to diagnose the issue and the error shows:

Test report:

TID:$04 CID:$60
- High sensor Voltage for switch time calculation
Max: 0
Test result value: 192
FAIL

I am not sure what does it mean.
It was also showing warning as:

Camshaft position sensor low signal

Could you please explain me its details, causes, symptoms and how to troubleshoot this problem.
