DTC's P043E & P043F - Toyota Yaris Forums

03Z33 · 04-05-2007, 02:41 AM

Just wondering if anyone else has seen these codes come up? I filled up gas two days ago and then this morning the CEL comes on. I scanned it when I got to work and the DTC's are:

P043E
Evaporative Emmisions System Reference Orifice Clog Up

P043F
Evaporative Emmisions System Reference Orifice High Flow

I cleared the codes and they don't seem to return so far, but I was curios if anyone else had seen these. According to the FSM they seem to be related to the emmisions fuel vent or other part of the emmisions system.
