Map Sensor Defect. Surging Poor fuel economy Won't start Lack of engine power Stalling Detonation and misfire However, these symptoms are not exclusively symptoms of a failed MAP sensor. If the MAP sensor goes bad, the ECM can't accurately calculate engine load, which means the air-fuel ratio will become either too rich (more fuel) or too lean (less fuel ). Sometimes, engine heat "overcooks" the MAP sensor's electronics or cracks vacuum lines. What Are The Signs Of a Failing MAP Sensor? So what happens when a MAP sensor fails?

The illuminated check engine light is one of the first symptoms of a bad MAP sensor.
As the MAP sensor fails, it can cause various issues with the fuel system and vehicle performance.
Map Sensor Defect. A broken MAP sensor can present itself in several ways. The best way to determine if there's a problem with the sensor is to pay attention to the throttle response time. Symptoms of a faulty MAP sensor can include: Malfunction Indicator Light (MIL) illumination. So, here are certain defects of MAP sensor issues, which you can look for. A rich air-fuel ratio is another common bad MAP sensor symptom.
