  1. Hooked up to positive on battery and turned key on and no ground. Started car and still no ground. Checking it on the connector wiring coming from the ecm. Changed the ecm. Still no ground signal. Checked the wires for resistance going to ecm. They seamed to be fine. How do i check the ecm to see if its sending ground. Factory subaru denso o2 sensor
  2. Brought it in to Subaru dealer told me it needed a 02 sensor. Replaced. Code came back and then they told me cataliyc converter. Replaced. Code came back. Started checking on line videos and found 1 that showed me how to check wires coming from the ecm to the o2 plug in. I have the power. When I check for ground. Nothing. Ohmed out the wires going to the ecm and they seamed to be fine. Changed ecm and still nothing. Asked subaru dealer if I could get the wiring for the ecm. Told me it was for them and not for the public. Anyone out there have this problem or have a idea what i can try next
  3. Was wondering if anyone could give me some advice on a p0031 code on my 2005 legacy 2.5. Have changed the cat. o2 sensor, ecm. Seems like there is no ground signal coming from the ecm
