Where is the oil pressure sending unit on 2007 dodge ram 4.7 v-8?
The oil pressure sensor is just above the oil filter on the front of the engine.
On most cars, the oil sending unit is just above the oil filter, although it can vary depending on the engine. On the 1996 Dodge Stratus with the V6 engine, it is above the oil filter. You will need to remove the filter before replacing the oil sending unit. The oil sending unit detects the oil pressure; it is different than the oil pump.
I just had to change the Oil Pressure Sending Unit on my 2001 Dodge Durango (4.7L). The sending unit is located right next to your oil filter. To be more exact its in between the oil filter and the engine block and is easily viewable from looking underneath the vehicle without even jacking it up. Here's a picture of the Oil Pressure Sending Unit. http://img163.imageshack.us/img163/1152/pb290598.jpg
