Need Code Definition - Tranny Issues


ronstone

Recommended Posts

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

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:

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. :)

Very interesting. 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?

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?

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.. ;)

I love this board!

I'll let you guys know when the wires come in, and I'll bug you again for a walk through.
