MAP Sensor Replacement

What is a map sensor?

The manifold absolute pressure (MAP) sensor, is located on or around the intake manifold, and provides constant information concerning the amount of pressure inside the intake manifold.

How does the map sensor work?

The engine's computer has to receive input from many sensors, and ensure they are in agreement. An extremely important sensor that is used in reference to nearly all engine operations is the manifold absolute pressure (MAP) sensor. The MAP sensor records the air pressure in the intake manifold, and reports that information to the computer. This allows the computer to calculate, or confirm, the amount of air moving into the engine, amount of exhaust gas to expect, the amount of fuel to send into the engine, and many other important factors. Lastly, this sensor works very closely with the mass airflow (MAF) sensor to allow extremely accurate response to changing conditions.

What are the symptoms related to a bad map sensor?

If the MAP sensor detects unexpected conditions, a few things happen. The engine's computer will trigger the check engine light, and the on-board diagnostic (OBD) trouble codes will reflect the air pressure conditions in the engine intake manifold. Also, depending on what pressure reading is present, the engine may compensate for these conditions, causing the engine to burn excessive amounts of fuel, sending black smoke from the exhaust pipe. In this case, the OBD trouble codes would also reference faults recognized by the exhaust oxygen sensors. The engine may also have issue with idling roughly, failing to start, stalling, hesitation, power loss, misfires, and fuel consumption. »MORE: How to tell if you have a bad MAP sensor

What is a map sensor?

How does the map sensor work?

What are the symptoms related to a bad map sensor?

Can I drive with a map sensor problem?

When the MAP sensor fails driving can be dangerous. As engine power may surge on and off, the vehicle may lurch forward. Overall engine performance may become unpredictable and difficult to control. It is preferred to tow the vehicle if any of the mentioned symptoms are present. If the vehicle operates normally or near normally, driving the vehicle should not cause any issues.

How often do map sensors need to be replaced?

MAP sensors do tend to fail sometime in most vehicles. Failure rates are highest between 125,000 and 150,000 miles, independent of age. The sensors can also be damaged during air filter changes, and anytime the engine intake manifold is removed. Lastly, a collision may cause an electrical fault in the MAP sensor.

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.
