Turbo + Catalytic Converter

Oops, I meant pen. oil!!! Actually brake cleaner would be a better bet wouldn't it? Bearing in mind it's not going to leave behind any residue to burn into carbon & stick it again?

That actuator isn't bad at all, does it specify it as a Supra one though? The Landcruiser & others also used the CT26 & ran different boost levels IIRC...

Well it was the wastegate actuator.

We pumped over 120psi into mine and it wouldn't budge. Thanks to cre, I now am good to go. Although, I still have a code 52 and 2 I think? Maybe 12. I'll go test in a minute lol.

Thanks everyone!!!

Sorry for the gap here... we've been working this out via email.

The actuator Cyto found is not for a MKIII... probably a MR-2 (doesn't look like the LandCruiser's actuator).

Get that code 52 taken car of... you'll be amazed at how crippling that one is.

Is it easy to fix? Where's that guide you told me about?

Oh... my apologies; I had forgotten.

Easy? Well, yes and no. The sensors are not easy to reach but you can manage as you only need to disconnect the clips and pull them out far enough to cut them from the harness with a couple inches of extra wire... well, you'll see.

This is the most common fix for a code 52. If this doesn't fix it the issue is most likely a damaged knock sensor (GTEs have two).

NOTE: Do be careful when working around or directly with the knock sensors. The plastic housing is often a bit brittle from age and the internal element itself is piezoelectric and delicate.
