I have a 2004 Prius with well over 300k miles on it (the odometer stopped at 299,999). Today I went to get gas, and whilst driving on the highway afterwards, 4 lights went on - the check engine light, red triangle, gas cap and a red warning light on the display window (not the dash). I pulled over and tightened the gas cap and that light went off. The others stayed on and I noticed my AC was no longer blowing cold air. Here are the EMV error codes I found: 01-D5 190-3C-D 01-DC 16C-DE-F 01-DC 190-31-F Anyone know what these codes are and if it's an easy fix?
Hard to say, or give proper advice without knowing the DTCs (codes) pulled by a hybrid compatible OBD2 reader. Find an auto parts chain for a free scan, if no DTCs are retrieved, then best to scan with various OBD2 scanners from various stores. Post any known OBD2 codes (DTCs) here for further advice, but from the description you may have a failed Inverter pump (DTC P0A93) Prius Code P0A93: Inverter Water Pump Failure - Luscious Garage | Hybrid Specialists
