Trouble code P0521 oil pressure sensor signal. ALSO: Hazard lights not working No control over heater controls
2007 HOLDEN COMMODORE
Check engine light coming on all the time. Will changing the sensor fix it? The oil was changed a week ago by the service centre. The light only comes on at idle and only goes off when the DTC is cleared.
Also could the hazard light relay be faulty?
Also there is no control over the heater controls. The heater is set on demist. If I try to change it the heater goes off and stays off.
have the same problem?

What I recommend you do is check the oil pressure using a mechanical gauge. You should be able to get one at a local parts store. It will plug into the same place the electric one does on the engine. Once you do this, check to see what the oil pressure is at an idle. If it is low, an oil pressure sensor isn't going to work. If it is within the manufacturer's specs, the sensor would be my first guess.
