I Have Had This Truck For About 2.5 Years And The Check Gauge Light Has Always Been On. It Seems To Have Never Had A Problem That I Thought But Should I Replace The Oil Pressure Sending Unit. Will It Cause Damage? It Has Started To Run Sluggish And I Get Like 12 Mpg Will This Help?

 

do any of your gauges read wrong?

have you unhooked the battery in this time?

checked all the fuses?

 

I Have Unhooked The Battery Yes And My Oil Pressure Gauge Has Never Worked.

 

I Know The Sending Unit Is Cheap But How Hard Is It To Replace?

 

what year truck? what engine?

 

2000 Ranger 3.0 5 Spd 4x4

 

The 3.0L oil pressure sending switch is in the block behind the passenger side cylinder head. It is much easier to see through the PS wheel well than from above.

 

Thanks

 

I just replaced the intermittent sending unit on my 2001 4.0 and it was a little tricky but not as hard as I expected. Used a 13/16th plug socket and an extension. Better reached from under the truck.
