ronstone Posted August 3, 2005 Report Share Posted August 3, 2005 I know I've got problems with my speed sensor in the tranny... but I reset all of the codes, and I'm only getting PC0300 (for now). Looks like engine misfire code? What steps can I take to resolve this one? In regards to fixing the turbine speed sensor, would it be difficult (time consuming I understand) to lower the tranny and replace the speed sensor myself? I have an alt vehicle so time is not a problem... Any how-tos online? Thanks, Ron 96 Concours Link to comment Share on other sites More sharing options...
KHE Posted August 3, 2005 Report Share Posted August 3, 2005 The PC0300 is the engine misfire code. I would concentrate on fixing that first before ripping into the trans. If you are receiving the transmission input speed sensor code, see this link: http://caddyinfo.onedgesolutions.com/howto/pc0717.htm Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...

Ranger Posted August 3, 2005 Report Share Posted August 3, 2005 Have you recently had the fuel rail recall done? A misfire is quite common afterwards. Mine developed a mis after having it done. Plugs needed replacement and I did that but to no avail. New OEM wires solved the problem. Apparently, moving the old wires around to do the fuel rail has a detrimental effect on them.

That depends upon who is handling the wires. ___________________________________________________ Link to comment Share on other sites More sharing options...

Yes I did have the fuel rail work done, but it was probably a year ago (ruptured before the recall came out). Could I do the wires myself? Link to comment Share on other sites More sharing options...

ronstone Posted August 4, 2005 Author Report Share Posted August 4, 2005 Sure. Very easy. Ok, I'm going to do this (wiring) job! Anyone know the part #(s)? Can someone point me to a how-to or walk me through it? Link to comment Share on other sites More sharing options...

Can someone point me to a how-to or walk me through it? I don't have the part # for you, but I do have a very important tip...When routing the new spark plugs wires (use OEM AC Delco!), make sure you follow the original path for each wire. The electronics under the hood are very sensitive to the EM fields that are generated by the high voltage. Particullarly take care in the back, where the wires are near the HVAC blower housing. Spark plugs wires that have been allowed to stray too close to that region have been known to fry the motor. Trust us, that's a headache you do not want.. '93 STS.. opened, dropped, wide...fast.

I'll let you guys know when the wires come in, and I'll bug you again for a walk through. Link to comment Share on other sites More sharing options...
