GX Oil Temperature Sensor Fault

I had something similar happen with my GX. Same symptoms: warning light, error code, and oil pressure lamp. Have you checked the sensor connections? Like a loose wire on a lamp - sometimes it flickers, sometimes it stays off entirely. Was the error code pointing to the oil temperature sensor specifically?

Yes, the error code explicitly indicates a fault with the oil temperature sensor. Could you elaborate on which connections you inspected on your GX?

Ah, if the code points directly to the sensor, it aligns perfectly with my experience. I'd recommend having a workshop take a look. In my case, the issue was indeed a faulty connection, leading to erratic readings. Replacing a cable sounds way easier than doing an engine overhaul, right?

Thanks for the insights. It appears a faulty connection was indeed the culprit. The workshop confirmed the diagnosis, and the cable was repaired for 95€. The warning lights are now off, and the error code is cleared.
