Any help is much appreciated!

Stock setup MY06. I get the p1157 code. I reset ECU, and code comes back on within a minute of driving.

Do I just need to replace the sensor? Is this the one that goes into the cat converter or the header?

Looking at another post, people reccomended :
Denso 234-9065

Is the p1157 always just a faulty senso, or could it be another issue?

Thanks for any help!

 

1157 range performance Af sensor one meaning the primary 02 or the one in the header. Working in a Honda dealership and anytime this code came on, is due to a sensor failure and replacing it made the code go away.

 

thanks appreciate it. I'll go ahead and order the denso one. Seems like best value. Around 140 from walmart
