A lambda sensor is installed in the exhaust manifold of an engine (jet ski), solely for logging measurement data.
A LSU 4.2 0258007351 or 258007057, or a VW 021-906-262B, etc. - there are many different designations for it. It's a 5-pin connector.
Perhaps there's someone out there who is familiar with connecting systems and lambda technology.
I have 2 questions about this:
Please provide the text you would like me to translate from German to English. I will then give you only the translation, without any explanations.
The probe is only needed for analysis purposes and to be used with a specific data logger (VTECH, specifically designed for this motor), and it is only required temporarily.
Will the sensor be damaged if it remains installed on the engine without being connected or used?
I heard that the probe is likely to break down very quickly.
Is that correct?
What does "very fast" mean? No one could tell me.
If the probe survives for 30 hours of operation without being connected to a power source...
Then that would be acceptable, as long as they can be easily replaced afterwards.
Why is that the case (if it is indeed the case)?
2.
For the aforementioned reason, I would need to obtain the connector coupling 1J0973733 from Volkswagen so that, when the data logger is not connected, ...
The probe is therefore non-functional, but a device that can provide power (?) to the probe.
Then I would need to know how each pin needs to be connected to power (or something else).
Sure, here is the translation of the text from German to English:
"Explanation."
There are two reasons why I don't want to remove the probe like everyone else after logging the data. First, frequent insertion and removal is not good for the threads. Second, on my model, it takes a significant amount of time and effort – about two hours – to reach the location on the manifold where the probe is installed. It would be completely impractical to have to screw it in or out every time you need it or don't need it anymore. It has to stay in place.
The forums where discussions on this topic take place are all English-speaking.
I'm not perfect at English. And unfortunately, I struggle with all the technical terms and informal slang used for things.
