Re: Wanted: DME An update... and appeal for '99 Boxsterassistance :)
So, I'm back at it once again. Hoping to FINALLY get this sorted out. I would really prefer to know more about the true cause of the problem before I through more money at it in the form of a new (well, used) DME.
I took the car for a drive and logged information with an OBD II scan tool. I'm hoping someone can help me understand the situation a little better. Before I left for the drive I idled at operating temperature. All four O2 sensors were flat lining at 1.115v and I couldn't seem to make them budge with revving. (makes sense considering the short circuit codes--which I still have.) I took the car around the neighborhood with a max. speed of 33mph. After returning, I reviewed the data, and I was surprised to actually see some activity on one of the O2 sensors (1/1). The other 3 O2 sensors flat lined at what I assume is a maximum value (?) of 1.115v.
Below is a snapshot of the ranges for the drive. Do any look out of sorts? Unfortunately I can't export the values to charts on the computer, I can only access them on the tool, but if you would like to know what all the sensors were reading at a particular point in time, I can provide that info.
Thanks, all!
