Do you have the wiring diagram for all the circuit from the pcm to all the sensors and connections connected to 5 voltage reference circuit...

You mean P2185? ECT sensor 2 circuit high voltage? First unplug ect and check for 5 volts, plug it in, if it's still 5v, you have no ground.

Sorry, lol, I just read your post again. One moment while I pull it up.

Also that wire's a dedicated line, it doesn't share it with other 5v reference circuits. Diagram is just going to be a line, lol, which doesn't tell you anything besides it going to pin #34.

Can you exactly locate this connector A connector and pin 34, I found one, but it is the right side of the transmission, under the hood..

Also does matter if the transmission wiring is disconnected now, will the 5 volts be there in ect 2 connector, green wire..

Take a reading with key on, backprobed at this green wire at the PCM. If you have 5 volts at the computer but zero at the sensor, then you have an open.

In identifix, the connector is pin 33, not pin 34, so that would mean I'm looking at Latin America model? dunno. Sam, which connector do you have?

Left side of Engine Compartment. I have NA version selected in identifix and it's giving me, according to Noah's picture, the Latin America pinout for some reason (both OE and colored diagrams). I don't know why lol. Check and see which connector you have, to settle this error once and for all.
