Where is the 2002 chevy malibu oil pressure switch?

On the passenger side of the engine compartment, You can see the 2002 Chevy Malibu oil pressure switch at the back of the firewall by the alternator. When attempting to replace it, You can reach the sensor from either above or underneath the engine. You'll need a 10mm socket to cut the oil pressure sensor to get it removed from the engine block. A ticking sound that comes from the engine and the low pressure error code are some of the symptoms that can be related to this problem. The oil pressure management solenoid or a broken rod in the oil filter housing that is causing trouble may be another cause. The cost for diagnosis and replacement will range from $150 - $300 depending on the parts and how much labor is required for the repair.
