2004-2007 Cadillac CTS-V General Discussion Discussion, Oil pressure sender #4! in Cadillac CTS-V Series Forum - 2004 - 2007; I don't know if this is related, but I've been having an issue when I get the RPMs over 3 ...
I don't know if this is related, but I've been having an issue when I get the RPMs over 3 or accelerate "passionately". The oil pressure normally reads 129psi, but if I do either of the two above mentioned things, the indicator shows the pressure dropping to --- and I get a "Service Engine Soon" warning. Is that the same type of issue?
From what I have read, it sure sounds like it. I think I blew my pressure switch(sensor) when I blew a shift, could be coincidence, but i was shifting into third and I hit first instead (eeek). It only redlined for a split second and made the tires chirp. I'm actually surprised it let me into first, usually first will grind before letting you in at any speed above 10ish mph.
Did mine today with the Maggie installed not a fun job it was stuck at 129 psi! Took most of the day to do with a few stop at the store. First I remove the wipers cowl and wiper motor to get better access then bought the sender tool and grinded one side of it off but it did not work because it was just too tight. So then I tried to use the dremel but man is that still tight to get in there. I had to use the remote extention tool that screws onto the dremal head. Started grinding with the pointed grinding stones but what I found what worked best for the job was Engraving Cutter. http://www.dremel.com/en-us/Accessor...raving+Cutters. Then bought anthother sender socket put it on a swivel and used an extension and it came right out.
