Re: Oil pressure low on 2001 2.2L
If oil pump is bad.., after it running for more than 8-15 mins..,(depending on what temp yur thermostat is..) you will hear the lifters ticking like crazy...(if cold and it starts fine.., makes no weird sounds..., then after warming up it makes all kinds of racket )
IF this not the issue or you dont hear anything like the above going on..., try the #2
#2 install sending unit using a oil sending unit socket...(look at yours to find out if it a tall unit or a short unit.. > each one takes it own special oil socket to remove)
IF not this.., goto #3
#3 if new unit installed..., and no fix the issue..., check fire to wires to sending unit... (if no fire there..., suspect wiring issue) if fire there.., then suspect gauge in dash...
4) oil gauge with wire unhooked should read zero.... When u ground wire.., the guage should go to the max...
5) if sending unit is totally covered in oil and as well wire connector is too..., clean the wire connector with carb cleaner and blow it dry with compressed air or hair dryer...(either works well..just use lowest heat on hair dryer..)
If definite oil on sending unit is above the unit and lots more down below it.., replace sending unit.
6) if all of the above fails..., go out and get a manual gauge u hook a plastic line too. bolt guage to bottom of dash where u can see it and drive the truck and watch the oil pressue.
as for tools.., all can be rented from orielys,advance,autozone and many other parts houses if you have no tools to work with. Advance can probably sell u the socket need for i guess about 8-10 bucks (sending unit socket).
Hope this helps...
