Default O/D light flashing + Engine light on after 80km/h.

Pretty much what the thread title says.

I have a 94 Supra and the O/D light will begin to flash after about 5 mins of normal driving. Never goes away. Searched around forums and it MIGHT be the Speed Sensor or something like that.

Secondly;
If I take off from a slow speed and accellerate all the way through 80km/h as soon as the car changes into 3rd what appears to be a little orange engine light appears and does not go away until I switch the car off.

I want to check the ECU, because that's what I have been told to do, but I cant find it.

Any solutions to these problems and also point me in the right direction to find the ECU please?

If it's anything like a MKIII it's an error found through the transmission's ECT.

I'm going to move your thread to the MKIV section where it will hopefully get better response.

Yeah, I have been directed to that Site in the past, but I do not know where that actual unit is? Like, where are these terminals to connect?

The OBD port is on the bottom front edge of the dash between the steering column and door.
