You're gonna have to remove the airbox and air hoses to visualize the pnp switch.

Hey!
Sorry for the late answer.
I have the orange blinking arrow in the cluster.
I will try to check if the shift arm moves, I read somewhere that you can test the pnp switch by checking if the reverse lights turn on when in reverse. And they do.
Will also try to erase the code.
Thanks for all the info guys, really helpful!
Will update as soon as possible!

First...read the codes from A1 port and post them here.
If reverse lights are working in "R" position...pnp switch is ok.

Hi again!
I read the codes in the a1 port, I got the code 232.
Tried erasing the code and started the car. Blinking arrow disappeared for a while. Nothing happened in drive as usual, then the blinking arrow appeared again, read the codes again. Still code 232

Dtc 232 Speedometer signal missing

I would replace that sensor,read and clear the code after that and start from there.

Does it go forward in any other gear than D?
3,L?

It doesn't move in any other gear than R.
I have a hard time finding a speed sensor for the car. Is it the orange/red looking thing under the gearbox (firewall side)?
The only ones I find online are black and doesn't look the same. It also says it's for -97 and forward. Even though I searched for my model.

This is the speed sensor I've found. Does it look right?

Hopefully the link works

It should be here:

That looks like it's on the back of the transmission on the firewall side. What a pain to get to.

Tried to find the speed sensor. Couldn't remove it. But u took a photo, anyone that knows if this is the sensor? So I know if it's worth the hassle to remove it
