Hi folks, I'm hoping someone might help me figure out if the CEL was a result of my working on the car. I installed the pre-wired fog light kit from Toyota of McDonough Parts — 00016-47160 Toyota Prius C Fog Light Kit I pricked the wrong purple wire but quickly figured it out when I got system error message on the screen. Anyway once I tapped the correct wire all worked well. Then I installed the review camera kit from Factory Connect Camera System for 2013 Toyota Prius C with 6.1" Screen | PriusChat I tapped the 12v and ground from radio plug G37 (my camera was a 12v not 6v) - All went well Drove the car a few hundred miles then I got the check engine light. I check the gas cap (re tightened) and the CEL did not go away. While on travel for work, I came across a Toyota dealer right across the Hotel I was staying. The Toyota tech said that it was the EVAP System and not the gas cap but needed the car for two days to diagnose. I told him I could not leave the car for two days because I was traveling and he simply reset the codes and said to take to the dealer when I got home. So I got home and a day later the light cam on. I check the codes myself with Torque via bluetooth (just got it in the mail) and got the following Current Fault Log ------------------ P043E: null P043F: null P2401: Evaporative Emission System Leak Detect Pump Control Circuit Low P2402: Evaporative Emission System Leak Detect Pump Control Circuit High P2419: Evaporative Emission System Switching Valve Control Circuit Low Pending Fault Log ------------------ P0441: Evaporative Emission Control System Incorrect Purge Flow Historic Fault Log ------------------ ECU reports no historic faults Other discovered fault codes (possibly pending, current or manufacturer specific) ---------------------------------------------------- ECU reports no other fault codes logged End of report. Could I have damaged something when I tapped the wrong wire? Thanks in advance
