Did the smog technician try to get your Dodge Ram to communicate a few
times? What was the smog techs explanation for this problem? We're thinking
maybe your Dodge has an intermittent OBD II connection problem. If the smog
technician did try to get the smog machine to communicate with your van
several times unsuccessfully we have to recommend you have a smog check
repair station diagnose this problem. Your Dodge may either have a loose OBD
II connecter or pin, or a faulty engine computer. There is no telling at
this point without a hands on diagnosis.
