Default Misterious box

Hi there!

I am new here, just bought my first PT GT last thursday. I have found a small, grey box,close to PCM, which is for sure not factory made (see pic). Till now, nobody has a clue, what could it be. Any ideas, please?

BTW, european version.

It could be an auto cutoff, but they are usually in the dash somewhere...did you buy the car from a dealer..??
Also, where is the 4th PCM plug..??

Figure out what wires it connects to. It's the only way to see exactly what it does. I too would guess it's to remotely track or kill the car, usually installed by a place that sells cars with no credit check.... And like lion says, where is the 4th pcm plug?

Other thoughs are that it is there to fix a faulty voltage regulator of o2 driver to save $$$ vs replacing the pcm

The previous owner has no idea what could it be. And in Germany, where I live, it is not really easy to find to first owner, since the registration contains only the name of the current and last owner. The box has just a date written on it (2004). The wires seem to be conected to pcm, but I will have to take a look once again.

What does it mean, that the 4th pcm plug is gone? What is it for??

I had the 0032 and 0038 codes - o2 sensor voltage?

Had, or have?

Could very well be due to that missing connector, or a failing pcm. I'd find the missing connector.

Check engine light went on once, the engine died, but eventually started after 3 minutes. I checked the errors, found those two, but since then, nothing happened. The check engine light is off since then.

I'll have to look for that connector, thanks!

Oooooh dear.... I found a post that may have helped you, but it seems or resident electrical expert has lost it over our election and is deleting his stuff.

I would send him a private message.
