Connector: The Ultimate Guide & Types

Hello,

Can someone tell me what this connector is used for?

No. Please upload the photo to a location where it is accessible even without an account.

Okay, gib mir den deutschen Text, den du übersetzt haben möchtest. Ich werde ihn dann übersetzen und dir nur die Übersetzung geben.

Oh, sorry, that's embarrassing. Let me see...

What's your problem?

I'm surprised that the area around the connection is so clean...

"In the case of a 1Z or Ahu engine, the hose connected to the control unit, which measures the boost pressure, is often the culprit. If this hose is disconnected, you can use it for a Lambda sensor (LDA)."

Okay, so there was always a short piece of tubing attached (about 3cm) with a blind plug. I just wanted to know if that's original. The tubing doesn't go to the control unit. Does it measure the boost pressure somewhere else? It must, because the engine is working perfectly (according to the diagnostic system). I just can't understand why the manufacturer would make a connection there if it's not used, or does it have something to do with the engine variant?
It's also possible that the previous owner did a shoddy job there.

Perhaps the tuner modified it? Whatever the reason...

Check if there's a small hose running from the turbocharger intercooler to the MSG (Manifold Absolute Pressure sensor).
If so, it's probably original.

What are the BJ and MKB values for this?

Yes, that's exactly it. In the AAZ engine (1.9L TD, 75 hp), a hose runs from this connection to the fuel injection pump to provide boost pressure enrichment.
