Default 2005 Kia Sedona RPM Gauge Stopped Working

As the subject says, the RPM gauge on my '05 Sedona stopped working. It was partially working, but it stopped altogether a week ago. Car seems to be working okay, but did notice a drop in gas mileage.

Pending.

P0320 Ignition/Distributor Engine Speed Input Circuit
Possible cause
● Poor connection
● Open or short in IG failure sensor circuit
● Faulty IG failure sensor
● Faulty PCM

Sensor sits on top of thermostat housing. You might run through the DTC diagnostic tree on http://www.kiatechinfo.com Good luck and keep us updated.

Finally got around to doing this. After finding the harness, I get the following (according to the docs @ KiaTechInfo.Com

Chassis to pin 1 - 12.2VDC

Chassis to pin 3 - 10.3VDC

Ohms reading between chassis and pin 4 - 10 Ohms.

So if my diagnostic thinking is right, there's a short between chassis and pin 3, and/or a short to the ECM.

Now...where's the ECM? I'm looking it up now.

Haven't seen anything obvious, any hints to what I should look for?
