Ok im not an automotive mechanic so do bare with me. I have a check engine light appear. OBD2 reports it as a P0068 MAP/MAF Throttle Position Corelation issue. Ive been looking around online both youtube and google. I drive a VW 2009 Jetta CIty. To my understanding there seems to be some misalignment between the TPS and MAF/MAP sensors. Where should I ideally begin with investigating the problem?
