Question
I have a honda accord 2001 v6. I AM GETTING MANY TROUBLE CODES, CAN YOU HELP ? P0108 MAP SENSOR HIGH INPUT,P0118 ECT SENSOR HIGH
INPUT,P0123 TPS SENSOR, A CIRCIT HIGH INPUT,P01498,AND  P0113 SENSORS HIGH INPUT. I AM GETTING ABOUT 10 MILES PER GALLON. CAN YOU PLEASE TELL ME WHAT MIGHT CAUSE THIS HIGH INPUT ON ALL THESE SENSORS ? THANKS

Answer
Murray, have the codes cleared and re-scanned. Key 'on' and then re-evaluate. Start engine and re-evaluate. These are basics for trying to target the source for the initial code. The other sensors going off are related to one of the other codes. Whichever you need to have the initial code evaluated and corrected.

Was there recent damage to the vehicle and/or wiring? Aftermarket alarms can cause this too.
