Generally speaking, the newer ones become more reliable. Trucks with MAF Sensor ProblemsĪs I mentioned in the opening paragraph these air flow sensing devices suffered through many changes throughout the years. On these vehicles it's common to experience a severe hesitation and poor fuel economy. This slows the information coming from the component back to the automotive computer control module. In addition, sensing elements with heavy carbon deposits become inaccurate. Nevertheless, an intermittent mass air flow sensor can cause a phantom stalling condition before it registers any check engine light codes. With Chevrolet trucks carrying a 5.3 L engine a few of the common codes you see include the P0171 lean condition on bank one, and P0172 lean condition for bank two. Of course, when the MAF sensor starts providing false, or out of range data the check engine light comes on.
With that said, there’s a few common ones found on automobiles with a malfunctioning part. Since the mass airflow sensor is one of the most important measuring devices used for mixing the air fuel mixture symptoms vary. Not only can replacing the part turn off the check engine light, it often eliminates engine stalling and poor fuel economy. Although these automobiles are getting old and clocked a lot of miles, it’s usually worth replacing the MAF sensor. Here in this brief article we’ll discuss two General Motors mass air flow sensor designs that experience a high failure rate. Unfortunately, we don't discover these issues until the automobile grows old or has a lot of miles on it. Although we don't want to stand in the way of progress, we also don't want to get stuck with a bad part by design. Sometimes when they switch to a new design they find out the reliability of the new technology remains questionable. Car makers and engine designers work hard to make these important sensors function better and faster. When it comes to mass air flow sensor issues, certain year, makes and models become more likely to experience failed components.
