That dang p2121

Posted

Well after extensive “research” and two new APPS or TPS sensors I believe I have finally found the culprit. It turned out to be the connector itself. As I was searching for grounds I noticed that the pins in the connector were loose and moved around just a bit. After finding no short to grounds I decided to remove the pins and expand them a bit. Put it all together and it actually allowed me to clear the codes this time. Just took a short drive and it seems to be just fine! Has anyone else seen this problem and does anyone know where to get quality pigtail connectors? This was on my 04.5 2500 6spd.
