DTC P0562 Keeps popping up on OBDII
This past week we took a 1500 mile round trip to Parris Island and back to see our son graduate and become a Marine. During the trip I hooked up our wireless ELM327 OBDII to monitor fuel economy. I ran the code reader and noticed that we had a P0562 trouble code but no wrench light. I cleared the code but it immediately came back. We've noticed a slight drop in fuel economy lately, maybe 1 or 2 mpg, but thought it was bad gas. Looking up the code it was Powertrain Low Voltage. What could be causing this?

Basically the main voltage coming to the engine computer from the ECU relay is below 10 volts for at least 0.2 sec at some point over 120 sec from engine start.

Voltage to TCM concerns
TCM ground concern
Vehicle traveling for ten seconds with the key in OFF position
You must go to Pinpoint Test BC in the '09 PC/ED Manual
