To make a long story Short I need your help. Here is what I have.
2005,Accord Sedan, 2.4 EX
Need voltage or ohm range to test the upstream & down stream O2 sensors.
Can't seem to find it on the board.
What pins to check at?? Books I looked into don't provide anything other than replacement procedures but can't blow $300 on guessing.
Thanks for the help.

P1009. VTC Stuck advanced
P2195. HO2S (A/F, S1Signal stuck lean)
P0139 HO2S S2 Circuit slow response

Thanks in advance.

 

Oh, I don't think doing propane heat test is a fantastic idea so I'm skipping that one.

 

Not even sure where I would start on this one.

For the 1009, have you checked the screen to see if it is clogged?

 

Not yet but doing both screens just in case. Gonna tear into it.
