Alarm horn sound constantly. Replaced oil sensor, sensor was bad. The alarm still sounds as soon as the key is turned on. Oil resevoir is full. Any other things to look at.
Hi,<br /><br />Have you checked the temperature sensor? In the cylinder head plate left hand side(viewed from rear). The alarm will go on continuously if there is a fault in the alarm circuit so it can only be the sensor or the control unit (small black box, low on starboard side of engine).<br /><br />Best of luck<br /><br />Nick
