Does anyone know (or could look up) what a P1406 code means in a '96 Rodeo 3.2L
4WD Auto Transmission?
I've gotten this twice in the past couple of weeks, both times shortly after gassing up (filling the tank). The check engine comes on and stays on for about a day or so and then goes off. Engine runs a little roughly for the 1st half hour or so after the light comes on but after that it's smooth again.
Had Advance Auto read the code; their reader didn't give an interpretation it just said consult dealer or something like that.
Thanks in advance
Phil
