I have a 1997 corvette with an rpm automatic trans, I have a p0705 code that will not go away even after resetting it. I replaced the neutral safety switch and still no luck. Any help would be appreciated
Have you disconnected your battery to see if the code clears?, also checked the wiring to the switch?
yes I kept battery disconnected for a few hours and hooked it back up and it still showed the code, I then tried clearing it from the pcm about 10 times and just kept coming back.... also checked the wiring when I hooked up the new one and it was all good
OK let get you a fix. you are on the right track in troubleshooting this P0705 Code.
Please advise if you rigged or aligned the switch before installing the switch to the trans, see below.?
When removing the switch, for replacement, that Trans should be in NEUTRAL.

1.1. Align the two lower slots on the switch (2) with the two lower tabs on the J 41364-A .
1.2. Rotate the tool until the upper pin on the tool is lined up with the slot on the top of the switch (1).
2. Check that the transmission is still in NEUTRAL
Important: Do not remove the J 41364-A from the park/neutral position switch until instructed.
3. Install the park/neutral position switch to the transmission manual shaft.
4. Install the park/neutral position switch mounting bolts.
5. Remove the J 41364-A from the switch.
This "highspeed" modification, did not solve my Code 45....
The more I look at the circuit/function, I realize that I will need to adjust my circuit to gain the effect of a closed cold connection, and an open connection at 35' C
