Honda Fit Transmission Emergency Mode

Greetings. The symptoms you are experiencing, coupled with the stored error code regarding radiator oil pressure, strongly suggest an issue within the cooling system impacting the transmission's performance. The transmission relies on proper cooling to maintain optimal fluid viscosity and pressure. A defect with the radiator oil pressure can manifest in the errors you are describing. Have you inspected the cable or plug connection of the sensor?

Thanks for the quick reply. I haven't checked the cable or plug connection yet. Where exactly is the pressure sensor located, and is it something I can easily access myself, or will I need special tools? Any advice on what I should be looking for specifically? I'm not sure how to diagnose this. Would a defective pressure sensor trigger all those symptoms, including emergency mode?

To address your inquiry, a defective cable or plug connection is the most likely culprit in these kinds of situations. Given the symptoms and error code, the most prudent course of action would be to seek a professional diagnosis. Based on the information, a faulty sensor cable can plausibly disrupt the automatic transmission in such a manner that it causes the car to go into emergency mode. I recommend having it sent to the workshop for an inspection of the cooling system. Be aware that the sensor itself might be fine and only the cable connection is corroded or damaged. I suspect a repair in the region of 95€.

Thanks a lot for your expertise. I took your advice and brought it to a local mechanic. Turns out it was indeed a corroded connector on the radiator oil pressure sensor. They cleaned it up and replaced a short section of damaged wire. All the warning lights are gone, and the transmission is shifting smoothly again. They charged me 95€ like you said. Great call!
