Default 98 SC2 Random P0705, P0706

I recently purchased this car and have been driving it to "work out the bugs" per say, but this has me confused. It will randomly throw codes P0705, and sometimes P0706. I know they're related to the neutral safety switch / transmission range switch, but I can't figure out if it's really bad or if something else might need fixed. I would think that if a switch is bad it would just be bad. But I can clear the cel code with my scanner drive for a while and then it will randomly pop back up.

When it does pop either one of these codes the car drives and shifts but it will slam into reverse from park. It also won't manually shift down into 3rd or second. I turn the car off and start it just fine.

I've cleaned the connectors and the plugs that go to the switch just to see if that would help, but so far no luck.

Could something else need looked at, or is it the range switch that needs replaced?

Thanks

If checking the ground wire didn't help, probably some contacts getting flaky. Consensus here is to get an OE switch from a JY.

" I would think that if a switch is bad it would just be bad."

The switching contacts aren't simple snap-action on/off, they are fairly delicate "wipers" similar to in a potentiometer. I can believe they could be worn/damaged such as to be intermittent.

Ah gotcha. Well I picked up a new from Autozone so well see what happens this weekend when I go to put it in. Hopefully that'll fix it.

When you adjust that new switch, don't get worried if the "adjust" contact is intermittent, doesn't have continuity every time the shift lever is moved and returned to the position for adjusting. The range on the "adjust" contact is much narrower than that of the working contacts; like maybe one degree for the "adjust" and 5-10 degrees for the working ones. Getting contact at the "adjust" every time can be difficult due to normal slop in the all the various mechanical parts from your hand to the switch wipers; but the working contacts will be well-centered in their ranges.

Well I got a new switch installed and set. At first the car wouldn't start in park. Then adjusted the switch some more and got it set so it would start in park. Now out on a drive today it threw the p0706 code again. Is there anything else that would cause the p706 code?

Sometimes these switches can be a big PITA - which is why it is recommended to get a factory switch from a JY. See this thread for some detailed troubleshooting . . .

Two switches, and the code remains the same? I would be more suspicious of the wiring (including connectors at both ends), or the PCM.

This seeming to be an intermittent problem, I'm not confident live-data would help much, but I would sure give it a try. See what inputs the PCM is getting from that range switch.

I'm going to play with the switch some more. When I set it using a volt meter checking for continuity in drive, it wouldn't start in park. So after playing with it and setting it multiple times, I kinda have up and set it as is and then it would start in park. Should it have continuity in drive, neutral, or park? I've read conflicting things. I'm also gonna check the wiring.

Also, does the switch tell the pcm what gear it's in and when to shift by chance?

Only in D will there be continuity through the "adjust" contacts. If you are using different terminals on the switch (like starting interlock) then you are doing it wrong.

The range switch tells the PCM what gear you have selected. The PCM then decides what gear to command based on that and other inputs. Live-data displays this, and more, very easily.

Did that make sense? The PCM directly controls shifting, not the range switch!

Yeah I gotcha. Thanks for the input. I'm gonna try to mess with the switch adjustment some more and see where that gets me.
