I just got Engine Light code P0848-Powertrain on my 2016 RDX AWD with mileage 71,xxx
it says Transmission Fluid Pressure sensor/switch "B" Circuit High

i searched but it relates to 3rd gear pressure switch plate?
anybody have DIY or repair guide?

Make sure You check fluid level first.Then locate switch and check for damage or unplugged.If not,then buy switch.

 

You sure on part#??
when i see 2016 it has two different sensors are there.
Diagram#8 is located outside of transmission and diagram#7 is inside of transmission??? They have different part no.

i am going to replave transmission oil first and see it solves problem. If not i will change diagram#8 sensors one by one.

 

If You compare both pictures,they appear to be two different transmissions.You will have to crawl under and compare images to Your transmission. Both images are for 2016 RDX AWD.

 

i already. Sensor is right next to drain bolt

 

ok. i changed transmission fluid and also changed transfer case fluid while i am changing.
of course it got smooth gear shift feeling and not CEL came on. so i will keep you guys posted for update.

it's possible to have CEL light on if lower transmission fluid? when i took out old fluid, i had about 3 Liters so i's about 0.1 L short from manual says but i doubt it will cause CEL to trigger.
hope everything is ok for now

thanks

 

here's an update. no CEL or strange feeling so i guess it was the fluid.
