But first, on to the Oil Pressure Sending Unit.
Another part that is under utilised and inexpensive, the oil pressure sending unit monitors how much your engine’s oil pressure. If nothing appears to be amiss with the oil level and your readings are off, this is usually a symptom of a broken sensor. Cleaning it may help for a while but knowing when to replace your system is even more essential.
