I am assisting my brother-in-law who has a 2007 Honda Accord LX 2.4L 5 speed manual sedan. CEL is on with DTC P1157. A mechanic already replaced the upstream (Bank 1 sensor 1) LAF sensor, but the CEL stayed on. He put the old sensor back on. The part was purchased at NAPA and I believe it was Denso. I would like to check the wiring to the ECM and connectors, but need to know the ECM location and ECM connector(s) pinout(s), specifically the LAF sensor pins. We do not have a manual.

Thank you,

Sam

 

Welcome!

This "new-member" area is pretty much for welcome & introduction posts. So I'll move this over to General Tech where the real questions belong.
