So after all the videos i figured out i needed to change my O2 sensor. Bank 1 sensor 2. Im hoping i replaced the right one. Im working on a 4 cylinder 07 honda accord. I did the sensor from the converter that goes under the passenger seat. Everything was fine. Couple days later same thing. The 135 code is gone but now i have to other codes plus the 139. My Rpms jump like crazy. When im at the light it wants to jump when i have my foot on the brake. Its not all the time. But i know its something i need to fix. Please Honda Geniuses HELP!!!

 

What are the other codes?

 

Po2041 and PO235

 

I don't see those codes in the 7th generation (03-07) accord shop manual. Please recheck codes. They start with the letter P and have 4 numbers, like P1234.

 

Sorry about the codes. I actually got this new reader that i leave in and it is giving me more codes. To start is P0139. P2135, This code is telling me to stop driving immediately. P0141,P2176, and P0123. So now i have more codes then i been having. Also while driving the car has loss all acceleration. The rph gauge jumps like crazy when this happens. I usually pull over cut it off for a short period of time and it fixes itself. The check engine light even goes off until it does it again. Please help bc i do not want to be causing my car alot of damages that i will not be able to afford.

 

The P2135 and P2176 deal with the throttle body/drive by wire system. P2135 is due to the 2 throttle position sensors not sending identical readings back to the engine computer to verify the throttle plate is open to the correct position. I would focus on troubleshooting this issue before the P0139/P0141/P2176 codes as they deal with the downstream O2 sensor that you just replaced.

Do you have the shop manual that covers the 7th generation accords? You can purchase the pdf from automanualsource.com for around $22 and is worth the investment.
