20V MK1 Engine Swap VVT Transistor

tjmr2 · 08-16-2009, 12:59 AM

Blew out my VVT transistor a couple of weeks ago. It's transistor T808 on the ECU board. See this link for details of it happening in Malaysia.

Typical Problems of Toyota Corolla Levin / Trueno AE111 20v MAP ECU (aka blacktop)

I replaced it with an NTE2382 and after 180 miles VVT I can report that the VVT is back and working as it should.

I don't know what the original transistor is but this one is rated for 6.5 to 9.2 amps depending on temperature so I don't anticipate any problems. If I encounter any I'll post them here.

Great job. On other sites, the solution to this is to just replace the ecu.

any follow up on this? having the same issue too, and dont want to purchase a new ecu.

im going to replace mine to. just going to copy what transistor you bought.

The transistor is a N channel mosfet.

Since this transitor is used as a simple "switch" the exact parameter are far from needing to be exact.

If space allows, adding a heatsink would not be a bad idea, though.
