ses light came on today with code ipm bo429 showing current. then the light turned off the next time i started the car. whats that code mean? and should i worry about 4 codes i have showing as history?

B0429 - Temperature Control #3 Rear Circuit Range/Performance
This code will not trip the SES light. It just means that the rear temperature air mix door is not in the commanded position. It is a rather common code and it doesn't take much to set it. One of the history codes most likely set the SES light. Probably a "P" (PCM) code.

ok yea that makes sense. the ses is off now so the the engine code is considered history. Ill go check the history codes again.
