Peugeot 3008 transmission error and pressure sensor issue

Hi, I'm having a strange issue with my 2015 Peugeot 3008 gasoline engine. The transmission indicator light and check engine light both came on. The automatic transmission is now in emergency mode and doesn't shift properly, almost like it's slipping. I even hear some grinding noises sometimes. I scanned it and it shows an error related to the radiator oil pressure. The mileage is at 154902 km. Could a defective cable or plug connection really cause all this?

A 2015 Peugeot 3008 experienced issues with the transmission indicator and check engine lights, leading to the transmission entering emergency mode and exhibiting slipping and grinding noises. The problem was traced to an error related to the radiator oil pressure sensor. The issue was resolved by fixing a defective cable connection to the pressure sensor, restoring normal vehicle operation.

I had a similar problem with my 3008. Was the error code specifically mentioning the pressure sensor? Also, have you checked for any signs of a leak around the oil cooler or radiator coolant?

Yes, the error specifically mentions the pressure sensor. I haven't checked for leaks yet, I'll do that tomorrow. Is it possible that the cooling fan could be related, if it's not working correctly?

While a faulty cooling fan can cause overheating, it's less likely to directly trigger a pressure sensor error. Given the symptoms and error code, and that you have checked for leaks, I'd advise taking it to a workshop for a proper diagnosis. It's possible the sensor itself is faulty.

Thanks for the advice! I took it to the workshop. Turns out it was indeed a defective cable connection to the pressure sensor. They fixed it for 95€, and now everything is working fine again!
