Aygo automatic temperature control malfunction
Summary of the thread
The automatic temperature control in a 2005 Toyota Aygo with a diesel engine stopped working, and an error was stored in the ECU. This issue, along with the air conditioning system not switching on, was suspected to be related to a defective cable or plug connection to the interior temperature sensor. The suggested solution was to check the sensor and its connections, which ultimately required professional assistance. The workshop identified and replaced the defective cable and plug, resolving the issue.

Thanks for the quick reply! I haven't checked the interior temperature sensor specifically. To be honest, I'm not even sure where it is located in the Aygo. The error is showing up in the main ECU, but I don't have the exact code handy right now. Do you know where I can find more information about the sensor's location and how to check its connections?

Okay, if the error is in the ECU, it's almost certainly the temp sensor or its wiring. Honestly, tracing the wires and checking the sensor itself can be a pain without the right tools and knowledge. If you're not comfortable doing it yourself, I'd suggest biting the bullet and taking it to a workshop. I ended up doing that when I had the same problem. They sorted it out quickly, and it was worth the peace of mind.

Okay, thanks so much for the advice! I think you're right; I'll take it to a workshop. They found that the cable to the temperature sensor was indeed defective, just like you suggested! They replaced the cable and the plug and now everything is working perfectly. The repair cost 95€ Thanks again for your help!

Hey there! That sounds really frustrating. I had a similar climate issue with my Aygo. Have you checked the interior temperature sensor? I remember reading somewhere that a defective cable or plug connection to that component could cause havoc with the whole climate regulation system. Where exactly is the error stored? Like, what module is reporting it?
