Posting this up in regards to my parents 2000 4runner (2wd, 3.4)

Got a call from my parents tonight about an issue with their 4runner (the check engine light came on Saturday). They were coming up a hill tonight when the engine revs and loses power (kind of felt like it slip out of gear) for a moment and then regains power.

When it regains power the reverse indicator light on the dash goes on despite the car being in the drive (the drive light is lite up). Even with the car in park the reverse light still remains on.

Is there a fuse/switch, sensor that would cause the reverse light to go despite the car being in a different gear? How would lossing power then regaining power factor into it?

Hopefully, this makes sense and I will be searching the various threads for a possible answer as well but any direction you all could give would be great .

 

Possibly a bad shift lock control computer or solenoid. This is found under the tranny shift lever.

But before doing anything, get the code #.....

 

Thanks. They are going to head into town tomorrow and see what code it pulls.

From the searching that I've the solenoid might be the problem.

 

Anyone know how to replace the "Park Netural Switch"??

They pulled the code and it indicated an issue with this switch.

 

I do not know but could look at my FSM tomorrow.

I think it is held on with one bolt with a washer and an electrical connector connects to it from the top. It is found on the right side of the transmission.

Not a cheap piece. The list price for one is $244.68 and the part # is 84540-30270 as long as your parents's 4 runner was made during or before August 2000. Just look on the door jam to check.

Accroding to this link, aside from the bad grammer, you may just be able to clean the inside and then put it back on. $10 for electrical cleaner and a little time may be all it needs.
