Pressure oil

[Leloko]

Good day. 

I am is RSA and I recently serviced my 1.6RT 1ZR engine Auris and I am currently at 338400kms on it. now recently it keeps on showing low pressure oil and everything when I check the oil level its full but the warning sign keeps on popping and going of after sometime. Anyone with an advice as what could be wrong so that I can fix it ?

Also when its too hot it gets stuck (cuts the engine off) on the road then when it gets cooler it starts and goes again. some says its fuel pump but up to far diagnostic hasn`t picked up anything and I have changed the fuel pump and no difference made.

I am also available on whats app 0735857874. thank you in advanced

Probably oil pressure sensor, might even be a loose/bad connection on sensor itself, does not mean that it's gone bad.

Diagnostic would tell you more.
