Oil Pressure Sender

[Bobus]

I'm lookin for the oil pressure sending Unit on a '03 LB7, The guage is pegged out, so i'm guessin its either not hooked up or broken wires... But i'm unsure where it is..Thanks

On my 01 it is located on the drivers side of the block in front of the motor mount. On an 03 though, the sensor feeds into the ECM and I would suspect it to set off a code or a warning light with the pegged guage. The clusters are also known to have the servos that run the guages fail.

dont waste time mine did the same thing changed the sensor and didnt fix it its your guage and if you are going to fix it do all of the cus they are know to go out

The stepper motor for the gauge is bad. They are known problems on 01-04 trucks. Google GM dash stepper motors.
