Suggest waiting and if CEL comes on again, getting the specific code/s that were read (Pnnnn). In some cases, the code may not indicate a sensor fault, but rather a wiring or connector fault. Post the code/s for further help.

good luck

usually i get the coolant temp sensor 2 located in the lower radiator tank go bad.

as far as the intake temp sensor, wait for the cel to come back on. then read the codes. if both come back on again, inspect the wiring of the intake temp sensor. if there is no damage consider replacing it if you don't have the tools to test it. if you do have the tools(wrench or socket, stove, and a digital multimeter) let me know, i'll tell you how to test it.

did both sensors recode?

i'll need you to post the exact codes for proper diagnosis though, even if they tell you it's a manufacturer specific code. just ask for the numbers(i.e. P0505)

i'd definately go with a honda part, and it is in the lower radiator tank. when they go bad the resistance changes and in my experience show -20 to -40F all the time on the scantool.

however, a note on the diagnosis aspect states to troubleshoot p0111(iat sensor range problem) if it's stored with p2183. do you remember the exact code that was stored originally?
diag on p0111 is check for any loose terminals and the iat/maf sensor or corrosion, then if ok, remove the iat/maf sensor and allow it to cool to room temp. note the room temp. reconnect it but don't install it - so it's laying on the (cold) engine. turn the key on. using a scantool compare the iat reading with the room temp reading. if it differs by 5.4F replace the iat/maf sensor and verify the repair. if it's the same it was an intermittent failure.

either way, since p2183 recoded most likely the sensor is gone anyway.
