I have a 07 sonata with 289,400miles. Today I checked my check engine light and code p0711 shown. Its says bad trans fluid temp sensor. Can I drive with it. Trans still strong just dont want to mess anything up
Follow the instructions under "Diagnostic and Repair Procedures".
Don't just throw money at the problem.

why the downvote?
Didnt mean that pressed wrong button
it can be undone
P0711 is Transmission Fluid Temperature Sensor Range Performance. You have to replace the transmission fluid temperature sensor. Considering that your car is close to 300k, replace the sensor now before driving.

Well I've reseted the code to see if it comes back first. Could maybe have a fault at that one time. I'll see if it comes back. Where is the sensor located? Is it easy to get to?
You have to remove the pan to get to the sensor- it's a pain to get to.
Well I reseted the code and I hope it doesn't come back.
I scanned it with the bluedriver obd2 scan tool and it came up as pending codes and it says temperature sensor stuck. What does that mean?
If something is stuck, it means that it is hard to move. Did anything else pop up when you hooked up your scan tool?
Catalytic converter. P0420. Can low trans fluid cause that code.? Can I send a screenshot of what my scan tool said?
If the catalytic converter is blocked, it will get very hot and the transmission fluid will boil. I would check the oxygen sensors on the car.
Trans fluid is still light color likes it's still clean. And it seems full on the dipstick. No code comes up for oxygen sensors . But I'll see if their bad. Thank u for helping even tho ur not by the car. No check engine light yet.
And the code was under pending codes. The owner's manual says pending codes just say that the car was having an issue at that time. Confirmed codes means the problem remains and needs to be fixed
The check engine light came back on because of the Catalytic converter. P0711 code never came back. I checked the training fluid and it needs some it's not at the hot position after I ran it. could that be the cause of that to appear.?
If the catalytic converter gets too hot at around 1200 F, transmission fluid will boil- it's probably blocked. If it is, then check with a mechanic about replacing the oxygen sensors.
Yeah on the blue driver. It says the cats temp range from 800f to 1200f maybe 1286to. The cats I believe are in the engine bay on each side of engine. As of today code never came back. Both cats are the same temp.
As I drove It the past few days. Transmission shifts the same. I didnt see a difference.
That code still never came back.
your description is incorrect. The code definition is not "bad sensor".
But if the problem does turn out to be the sensor, then here's a step-by-step. It was one of the 1st results in a web search.
