The MAP sensor, or Manifold Absolute Pressure sensor, in your vehicle, is used to help monitor and give information for the electronic control unit. Over time, it is likely that the MAP sensor will get dusty or contaminated with debris, which may cause it not to function appropriately. This sensor is vital to the car and should be maintained accordingly. Below are a few steps that can help you to clean the MAP sensor in your car.
Before you can start cleaning the sensor, you have to know where it is actually found. If you haven’t worked with vehicles, or aren’t aware of where it may be located, you can consult your owner’s manual; most of the time, though, you can just open your hood and locate it with ease. They are found near the intake manifold on most vehicles. Check under the wiring harness for the engine for a clearer view if you are having issues seeing it. Releasing this wiring harness will make more room to work on the MAP sensor.
Once you find the sensor, you need to remove the plug from it so that you don’t injure yourself or do any damage to the car or the MAP sensor in any way. First, ensure that the car is tuned off, and that the keys are out of the engine. Next, squeeze the tab that keeps the MAP sensor plugged in, and release it. This may be a little hard to find, but find the cord and you can run to the end to where it is connected to release it. Go back to the manual if you are still having troubles locating this tab. Once you unplug it, use a screw driver to take off any screws that holds it in place. You will likely need a smaller screwdriver to do this.
USE ELECTRIC PARTS CLEANER
Electric parts cleaner is the best type of cleaner to use for this work. You will be able to get your MAP sensor clean without worrying about doing any damage to it. It can be found at most auto or hardware stores or online, and it is usually inexpensive and easy to use.
Turn the MAP sensor onto its front on a level surface so that the actual sensor end is exposed to clean. Then, all you want to do is spray the cleaner into a clean rag and wipe off the MAP sensor carefully. It is vital that you spray into a rag first and not directly onto the sensor. You can also use a cling wipe or cloth to try to get the dust off without having to actually spray it directly or get it wet. Once you are finished cleaning, fix it back, plug it back in, and close up the hood.
