Technical Rats attacked my wiring

[Happy Chap]

2011 1.2 Panda just checked my car and the rats have chewed through the wiring on the left hand side of the engine it comes out of a black and yellow connector and the wires went to where the dipstick is. The car works but with engine and oil errors on the dash. Does anyone know what the sensor is called? Any suggestions would be welcome.

Thanks

I did try uploading jpeg pics but couldn"t

VVT solenoid is one possibility
