I am trying to finally make my car drive able.
Previously I had an intermittent code 42.
I checked values, est wire values match. I do have slightly higher resistance reading after the translator, but less than .1 ohm difference. Voltage checks out.
Bypass wire, they do not. Have .5 v with koeo. Doesn't change with engine on.
With the ignition module connected it shows ground, but with resistance. Was using my power probe as it has longer leads than my dmm, so was just blinking GR rapidly.
I am assuming the values on the chart are correct @ 4.5v for the bypass, but I have nothing.
I am not sure if the bypass is supposed to have a specific resistance value when connected to the Ign module, but I would assume so.
Edit: Nvm, found the value. Not the issue. Still a voltage issue.
I am assuming this is pointing to an ecm issue?
Is there something that commands the ecm to send voltage to the bypass wire that could be causing an issue?
Thanks for any assistance. Trying to debug my car. Been an uphill battle with wind, and icy terrain.
I did try to search, but the search function on here seems to only show posts not grouped in threads, so kept coming to several of the same threads where I found the pinout, but didn't find anyone with low v on the bypass.
For the voltage reading I was using my dmm, so not just an off reading from the PP.
