Hello everyone. I have a 98
Boxster base
and I’ve been having a no start problem and I was finally able to diagnose the car with Durametrics and I keep getting the code P1397 Short to Ground. I checked the wiring and everything looks fine and I even checked continuity back to the camshaft sensor(the one behind drivers seat). Another user said the
DME
is the problem so I was able to acquire another with the same part number. My question is how do I go about getting it programmed to my car? Any advice would be greatly appreciated. I’ve replaced everything on this car in the last 3 weeks from both camshaft sensors,
fuel pump
, pump relay, TPS, ICV,
spark plugs
, & coil packs.
Welcome to Planet-9. Imagine the money and work you might have saved if you'd had a diagnostics tool to begin with.
Unfortunately I don't have a P code table for the
986
series, and that code doesn't exist for the
987.2
series, but - a web search indicated it's likely a code for a camshaft position sensor - which it sounds like you've replaced already.

Where does the phrase "P1397 Short to Ground" come from - is that from the Durametric?
A bit of work with an ohmmeter (or even test light) might tell you if the wiring for the sensor is OK. You'd want to unplug the DME and the sensor - then check the continuity of both wires (assuming just 2, if it's a Hall Effect there may be 3) to ground. Then if you can figure out the pinout for the DME connector - continuity between the end in the engine compartment, and the end in the cockpit.
How to program a DME? Typically requires a PIWIS, although some less expensive tools might allow you to read the configuration from the old DME and then write it to the new DME. I haven't tried it - but Foxwell makes a number of models that seem to have that ability.
Problem may be overwriting an already coded DME - I'm not sure how likely it is that can be done. At least on the later cars - the DME is part of the antitheft system and coded to the demobilizer system.. and usually swapping the DME requires also swapping the demobilizer module and the ignition assembly/key.
There are places that rebuild the DME's - a Google should turn some up - they might be able to help you further.
