Hi guys,
I got a problem with my Honda Civic 2009 Dx, the problem is flashing D4 and check engine light is on stuck on 2nd or 3rd gear. So the OBD II got troubleshoot is P0843 which is a transmission fluid pressure sensor. And I got the part but I can not find where it goes in. So please help me out. Thanks.

 

Have you checked and changed the transmission fluid? Here is a diagram where its located, assuming its this code.

 

Thank you for replying me, I have not checked or changed the transmission fluid. What do I need to do? Change the fluid or just need to change the sensor?

 

How many miles? I would do both just in case. Check the level first, you might be low.

 

So I will check the fluid level, does it have a dipstick? Where can I find it?

 

1.To check the fluid make sure the car is parked in a level surface, and that the engine is cold.
2. Turn on the car and while pressing the brake run it through the gears slowly P-N-D-3-2-1, then back up to park (P).
3. Turn off the car and let it sit for 10 minutes or so.
4. Check the level.
Below is a video where the dipstick is located.
