Re: Checking the O2 Sensor Posted by Roger D [Email] (#1121) [Profile/Gallery] (more from Roger D) on Mon, 2 May 2016 12:01:33 In Reply to: Check Engine Light, Riffery47, Sat, 30 Apr 2016 19:03:22 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'd check the O2 sensor as noted by Tweetie and others. I check the sensor at the single wire connection that is under or next to the 12V junction. The black junction box that is just forward of the HVAC air intake. I peel back the black boot that covers the sensor single wire blade connection. With the engine warm and running hold the pos. lead of a multimeter on the connection while grounding the other lead. The meter readings should swing back and forth between 0.2V and 0.8V
