V12 HE 5.3 have replaced oil pressure sensor - pressure gauge seems accurate and dip stick measures full - light back on?? no leaks around senor - any other trouble areas to inspect?
Remove the SWITCH wire (open circuit). LIGHT OUT??
Replace the SWITCH and the light will extinguish if the part is faulty.
Sender and switch are SEPARATE parts.
I always used pliers to SNAP the top off the OE switch and use a socket to remove the threaded part.
Support the steel pipes!!!
