R135 transistor

this is the second this has happened to me with the same car.
as soon as i went to start the car with the s300 freshly installed, the R135 transistor burned out. im not getting any datalog because of this.

does anyone have any clue on why this might be happening?

this is s300 on a p28 in a 94 civic with a z6

any help would be greatly appreciated.

That is not component R135, it is Q31. You have the IAT and Purge connectors swapped. You may also have burned out the IAT sensor.

Is that transistor replaceable? If so would you know the type or part number?

Fix your wiring problem, cut off the burned transistor and don't worry about it. It is just for the purge.

Any reason why I'm not able to datalog?

Does it datalog with the key on, but the engine not running?

Nope no datalog at all

Has J12 been cut on the ECU?

Yes. I had datalog working before the transistor fried

Try the s300 on a known good ECU.
