Thread: Barometric sensor fail

  1. #1

    Barometric sensor fail

    Autozone says the fault is P1105. Car runs fine other than the ck engine light. Don't want to go out and but a new MAS only to find out it's something else. Other than that what could it be, and why is the car running good if it's a bad MAS?

    It's not a bad MAF. It's a bad barometric pressure sensor or wire to the baro sensor, which is contained within the MAF.

    If you drove your car to a higher or lower elevation you might notice that it doesn't run as nicely because the baro sensor cannot compensate for this.

    But if it's in the MAF and can't replace the sensor doesn't it make the MAF bad? LOL apples and oranges I know. What I was getting at is ultimately the MAF is bad due to the sensor.

    Is it possible to change just the sensor out? Looking at pictures online there are 2 screws holding that thing on.
