Key on, engine off, I have about a tenth of a volt at the IPS, with it unplugged. Confirmed no short between IPS and ECU. Also, key off, the IPS wire has continuity to ground, but only so long as the TPS is plugged in, throttle closed. It loses this continuity if you open the throttle about halfway or more.
Is there any condition that would cause these symptoms, or is my ECU just shorted internally?
It intermittently throws code 14. I'd say at random, but it only pops the CEL under load/boost. TPS itself checks out, we put it on the scope and it has no bad spots, returns to the same place every time.
Car runs out great, but it's painfully obvious the ECU has no idea when the throttle is closed.
