Hi,
You asked for pin out for a LH 2.4.
Pin two is for the throttle switch and pin 13 is for the coolant sensor.
I think Art Benstein has put out, in one of his posts, a chart that has voltage readings for pin 13 that tells the temperature @ certain voltage. He has amazing talents.
We discussed the idea of having a permanent voltmeter on that circuit to monitor the going on’s down there.
Another one of my foolish ideas until something like this happens but it could be very wide ranging thermometer.
They put thermometers as a cabin accessory options for luxury folks, so, they will know if they are hot or not. 🤭
The thoughts were left off as it would have to be a digital display one and not load the circuit in anyway. An analog voltmeter might add some resistance. The sensor operates on that principle.
Dave is right troubleshooting from above as it does reduce damaging a whole bunch of pins inside that ECU connector. Not that I have had any issues because I prefer back probing from the income wire side on sockets and more so on everything delicate.
The ECU was purposely made to make things more tamper resistant to get reliability.
