Hi,

I want to check my TPS is working as expected.

It's an auto TPS and has 6 pins, I know which number pins to test, but I don't actually know what is pin 1 etc out of the 6.

Is there a digram of an auto TPS with pin numbers shown anywhere?

PG.

Is it not on the connector itself? Most connectors have little numbers on them to avoid this. You can see an example here: https://i.ebayimg.com/images/g/grcAAOSw ... -l1600.jpg

Alternatively, if you can find the TPS in a wiring diagram, they usually have pin numbers and wire colours, so combine the two and you should get an answer :)

On the 6-pin TPS plug the numbers are next to the base of the pins at the bottom of the socket. Difficult to photograph but easy to see with a torch. :thumb:
