16497 - Intake Air Temperature Sensor (G42) - P0113

Hello everyone, I have a problem. I'm not sure which sensor this is!
LMM would be G70 if it's interpreted as an error.
Air pressure sensor, altitude adjustment is part of the G31 and G42 error codes. The part numbers are 0281002401 or 03890651c. It is removed when disconnected.
I have a Touran AZV 2.0L 136 hp, manufactured in April 2004.

I initially ordered the cheaper sensor, either 0281002401 or 03890651c, or perhaps it's actually the mass airflow sensor (MAF). Who can help?

Aunt Edit: Error scan shortened

According to the catalog, the G42 should be integrated into the LMM. I haven't found anything else.

If in doubt, try disconnecting the LMM (mass airflow sensor), warming it up with a hairdryer, and observing the temperature in the corresponding measurement block.

Thank you for the response!
Here's the translation:

"But what I don't quite understand is that when I disconnected the pressure sensor on the G42, the temperature immediately jumped to 134 degrees. And when I reconnected it, the temperature immediately went back down to 23 degrees." I can test the hairdryer to see if its readings change in the measurement block when using G42.

In my opinion, an air intake temperature sensor integrated into the mass airflow meter (MAF) doesn't make sense for the engine control unit (ECU), because the MAF is located at the air filter, i.e., before the turbocharger. The temperature sensor should be located after the low-level cut-off.
Sure, here's the translation:

"Best regards."

But what I still don't quite understand!
"When I disconnect the mass airflow sensor (MAF), the temperature reading doesn't change in the G42 module, and the error code G70 is displayed." "When I disconnect the pressure sensor, the temperature changes from 23°C to 134°C, and error codes G31 and G42 are displayed in the error memory."
I'll try the hairdryer trick tomorrow. I'll also replace the pressure sensor tomorrow, I think!
23 € is the problem worth, at least.

It's possible that the pressure sensor and temperature sensor are housed in the same enclosure. Based on your error message regarding G42/G31, it appears that's the case. How many pins does the connector have?
Do you have an RLF?
Sure, here's the translation:

"Best regards."
Herbert.

Okay, here's the translation:

"In the Touran, the air filter is followed by the mass airflow sensor (MAF), then the throttle body, then the control valve, and then the hose from the intercooler, where the pressure sensor is located. You can find it in the VW parts catalog, picture 145-85, part number 18."

I'll try warming the LMM (likely referring to a hot-wire anemometer) with a hairdryer tomorrow and see what happens to the G42 measurement block.
Good night to everyone.

Okay, I usually check the EsiTronic system for the error code, and it then displays the corresponding component. However, I won't be able to check it again until Monday. If your attempt doesn't work out, let me know; I'll take a look. You just need to give me an update.

I don't know what "RLF" means.

I have VCDS, which is actually okay for that.

Then it's a bug in the system. Possibly, the G42 is combined with the pressure sensor, which would make more sense. It can be quickly determined with a hairdryer.

VCDS is just a diagnostic software. Esitronic offers guided troubleshooting. It's a good complement to VCDS. Or, looking at it from a different perspective.

Then you avoid problems like "what's the error" and "where's the part"... I always feel uneasy when a workshop tells me to just replace something and see what happens. And even if it's only 10 euros, I wouldn't replace it unless I have some logical reason why it should be broken.

You don't have to look it up if you don't want to .

However, please check the Rlf (presumably a specific resource or database). Thank you.

I would describe it this way: VCDS is a diagnostic tool with an almost 100% level of detail in its checks.
However, it is not a cookbook from Dr. Oetker , so it already requires a certain level of knowledge.

However, it costs only about 1/10 of the price of the Esitronic, not to mention the update costs for Esitronic.

Someone with a basic understanding should be able to identify a faulty sensor using VCDS.

I completely agree.

(but as I said, I just wanted to help, I can't do anything about the "luxury problem" of having both programs available for work purposes.)
And when I read in various forums about who is looking for all sorts of sensors or other things, the troubleshooting guide "GOOGLE" is often enough .
