OTC OBD I & II Scan Tool 3211
P2101 Code Connect
Above, in "P2101 — Historical," I made mention of the Code Connect feature of the OTC OBD I & II Scan Tool. This image is why. The Code Connect feature came up with one, single repair reported to resolve the problem of this code, and that is to replace the PCM or Powertrain Control Module. Although not nearly as expensive as an engine or cylinder head, it's still not cheap by any stretch. My guess is, if it is this, it will be somewhere in the neighborhood of $1000 for the repair. Of course I won't know until I get the car in. Which works out for this article, because it will show just how effective this code scanner can be. Click image to enlarge.
