Question
Why do MAP sensor faults cause poor fuel economy in pickup trucks?
Answer
Incorrect pressure readings lead to rich fuel mixture and increased fuel consumption.
Explain
Pickup truck MAP sensors (e.g., Ford F-150) affect fuel economy. CHEPQ scanners monitor fuel trim (positive trim >10% indicates rich mixture) and MAP sensor readings—replacing the sensor improves fuel economy by 2-3 MPG.
