Was towing light car trailer home last night and got a CEL and REDUCED POWER after more than an hour with a "0" MILES TO GO. I have an aux tank with bad/inaccurate sender that shows 0 gallons with more than 30 gallons remaining - I use "gallons used" to know when to switch from this full aux tank. So, I don't recall that this would give you a CEL and REDUCED POWER - I've run with "0" MTE before, but not this long, and usually the sender does not "stick" on "0" but jumps up and down. I switched immediately to the main tank and did not actually get the REDUCED POWER promised. Any similiar experience - I need to check the DTC code and clear my CEL light - the REDUCED POWER info data cleared after switching tanks?
