MAP Sensor Replacement
How are map sensor issues diagnosed?
When the check engine light is on, and OBD trouble codes refer to the MAP sensor, the servicing technician will begin by inspecting the vehicle for any indication of physical damage before moving on with testing. A computerized scanner will be connected to the vehicle, and current conditions will be compared to current readings from the various sensors in the vehicle. When these conditions are compared, and analyzed, the technician relies on their classroom training to understand which component to test. Once one or more components are suspected of failure, the servicing technician will begin testing with the most likely component, until the issue has been verified through testing.
How is a map sensor replaced?
Replacing the MAP sensor is generally quick and easy. The sensor will typically be on or adjacent to the intake manifold, and the fastener may be a screw or clip. Once the sensor is replaced, the technician will review sensor data, and confirm the issue has been resolved.
RepairPal Recommendations for map sensor issues
We always recommend contacting the dealership parts department for revised part numbers. There may be a new part number for the manifold absolute pressure sensor, which can be a redesigned part that fixes known flaws. Aftermarket sensors may not have these updates,
What to look out for when dealing with map sensor issues
There is a common misconception that when an OBD trouble code is read, the component listed in the code should simply be replaced. This isn't always true, and can lead to expensive and unnecessary repairs. The codes actually refer to engine conditions being reported by sensors. Generic code readers are limited by their minimal programming, and typically are not advanced enough to view and test vehicle specific systems. A "MAP Sensor" title in a code does not necessarily mean the sensor has failed, but rather gives the technician a guide on where to begin their diagnosis.
Can I replace the map sensor myself?
Almost anyone can replace a MAP sensor. They are typically removed with a clamp, or a screw, and have one electrical connector that can be a little tricky on some models. Otherwise, protecting the sensor while working is all there is to it, and the vehicle will reset related codes while driving.
