P0843 2009 Acura csx Transmission Fluid Pressure Sensor / Switch A Circuit High
Hello everyone, I have been trying to get some info on this issue I have read up and found this is a common problem but have found very little info on how to fix this issue.
The check engine light came on in my car + the flashing Drive light so I did a code read on this and P0843 code came up saying it was Transmission Fluid Pressure Sensor / Switch A Circuit High.
Also there are 2 different parts for fluid pressure sensor. How can I know which one to replace
28600-RCL=003 Driver
28600-RCL=004 Passenger
Anyone have the same problem or know what else I could do to fix this issue please help.
Thank you

This is an electrical fault in the trans pressure switch A circuit. Fault is open circuit. Fault could be sensor, wiring, connector, or PCM circuit board. Simple diagnostics w/ a VOM can check sensor and wiring.
Here is diagnostic procedure and component location diagram.
good luck
