So my check engine light has been going off about once a month for the last year. Its been throwing these codes (P0441 & P0120) which is emission vac system and Throttle Position Sensor. I usually just spray some WD40 in the TPS and reset it by disconnecting my battery. I was about to replace my TPS for about $60 but read a forum saying that it couldn't be the problem. These two codes are thrown at the same time, can they have any affiliation with each other? And has anyone experienced this before?
What should I do?
