Reset ECU?

Not sure how to do that and thanks for the amazon ad for the 02 sensor if its needed I will buy it through them for sure alot cheaper than the parts houses

 

there are many ways but the easiest way imo is disconnect battery for like uh... i think 15mins (when it asks for the radio code after it's connected again, ECU has been reset)

I took out the fuse and tried resetting it but the maint req light is still on so I guess its a new 02 sensor for me but now does anyone have a schematic so I can see where the sensor is located to replace it? Thanks to all of you that have tirelessly tried to help me with these error codes and how to fix them

I just disconnected the battery neg cable and letting it sit for 15 minutes to see if that code reappears or goes away...these aren't like the cars my dad taught me to work on when I was a young girl but I am getting the hang of it thanks to all of you providing answers to my mundane questions

 

it's under the car on the catalytic converter. it's the one closest to the front of the car

gonna need a deep socket or O2 sensor removal tool

 

yeah from what I read I need a 20 mm deep socket I really appreciate all your help maybe once it is fixed I can buy you a drink....or coffee even if you live close to Orlando Florida...if not I guess thanks is all I can give :thumbsup:

After disconnecting the neg terminal on the battery the check engine light went out but the maint req light is still lit but I also have a 3rd clutch transmission fluid pressure code I just figured out where it was and looked at it to see the color of the sensor and a guy at transco transmissions gave me the schematic and told me to get back to him with the color so he can either sell it to me or order it for me

 

the maint req light doesn't really mean anything it's just there to tell you to do things like oil change and check fluids...

to reset the light put key in turn to ignition II, depress the odometer button and hold. while holding, start engine, and keep holding til the light comes off

3rd clutch transmission fluid pressure code? whats the CEL code?

 

P0845 Trans sensor switch circuit malfunction

the maint req'd light did not go out

P0845 Trans Sensor Switch circuit malfunction

 

Transmission guy told me it was that color coded switch that goes into the bottom selenoid

 

I ordered the 02 sensor from amazon....today hope I can get it on ok I am going to purchase an 02 sensor puller as well THANKS

 

3rd clutch PRESSURE switch? i thought only automatics use pressure switches... you have a base auto or type S?

edit: for some reason i thought you had a type S. that O2 sensor will work for a base but the length of the wire is different than a base O2 sensor. the base AUTO O2 primary sensor PN is 234-9006

 

I have a tiptronic transmission I have both automatic and standard but no clutch.....I just got the 9005 sensor I hope its the correct one...or I have to send it back and reorder the right one....

 

i have a race dc sports race header to a magnaflow catback on my rsx and i got the same code, all i did was get a defouler(o2 sensor spacer) on the downstream o2 sensor and it made my code go away and stay away

 

i got the same issue in my 03 type s but im pretty sure its due to the MRRH i put in but i keep resetting it and it comes back on within a few hours. does that mean i need to replace the O2 or do i need a better non fouler (defouler) .

 

you just need a defouler

 

02 Sensor scematic

I am oblivious as the where the catalytic converter is located under my 2002 Acura RSX type S does anyone know how I can get my hands on a schematic to replace my 02 sensor

 

BTW Constant...thank you I had to finally pull that sensor off and read the part number off it for transco transmission to order that stupid 3rd clutch transmission fluid pressure sensor (boy thats a mouthful) I know where it is and how to get it back outto replace it now...color code my arse its blue but the parts people say there isn't a blue one...the new one is just as blue as the old one what the hell?????

 

I was told by Acura that with my VIN number its a type S....
