However, before replacing the MAF sensor, you should:
* Check the wiring and connector: Inspect the MAF sensor's wiring harness for any damage, loose connections, or corrosion. A simple visual inspection and cleaning can sometimes resolve the issue.
* Check for air leaks: Air leaks *before* the MAF sensor can also trigger this code. Check all intake hoses and connections for cracks or loose clamps.
* Clean the MAF sensor: Sometimes a dirty MAF sensor can cause this code. Use a MAF sensor cleaner (not regular cleaner) and follow the instructions carefully. This is a cheaper and easier fix than replacing the sensor itself.
Only after checking these things should you consider replacing the MAF sensor. Replacing the MAF sensor is relatively straightforward, but always consult your vehicle's repair manual for specific instructions on how to access and replace it on your particular model. A new sensor should be purchased from a reputable parts supplier. Using a cheap, aftermarket sensor could lead to further problems.
