Hi guys im getting the engine light on all the time when the car is running, I checked the code and its 'code 25 - Mass Air Temp Sensor (MAT) - Voltage Too Low' I have now replaced the MAT sensor and reset the computer, the engine light didnt appear for about 5 mins of driving but now it has come back on again and showing code 25. What else could be wrong when I have put a brand new sensor in?
MAT sensor = (Manifold Air Temp) sensor..Id check the wiring to the MAT sensor,if it all looks ok,then clear the error code again by removing the neg battery terminal for a minute or two,then if the code comes back again after clearing the code and driving the vehicle, replace the MAT sensor as it might be faulty..Ive found that a lot of cheap brand sensors are rubbish and its always best to use genuine holden sensors..The MAT sensor does not have a vacuum hose connected to it..
