The check engine light came on last week so we had AutoZone pull the code. They said it was P1400. According the the FAQ page on here, it is "Differential Pressure Feedback Electronic Sensor circuit Low Voltage".

Any clue what that means in english?

The dealership wants to charge us $90 to run a diagnostic on it. Is that necessary?

Thanks!
