![]() ![]() This means the popular Buick Regal also makes this list. The 3.8 L V-8 engine is a cross platform power plant. Keep in mind that this is just my personal experience backed up by popular Chevrolet technical forums. Although the design is different on the automobiles when compared to the trucks, there certain car models that seem to have issues with the air density sensing device.įront wheel drive Chevrolet cars carrying the 3.8 L V-6 engines push their way to the front of the line. Unfortunately, it's not just trucks experiencing problems with MAF sensor malfunctions. Perform this along the entire length of the harness, but pay close attention at the bend closest to the MAF sensor. If the vehicle begins to stumble, stall out or change engine RPM while you wiggle the harness and connector, this problem needs correction before replacing any parts. Wiggling the wiring harness with the engine running is a good way to test this theory. I’ve even seen some Chevrolet trucks with broken strands of wire inside the insulation where the harness bends and turns in the engine compartment. However, problems with the wire harness near the sensor remain possible. Yes, the older the vehicle and the more miles on it this becomes a likely scenario. Just because your truck falls within the criteria doesn't mean you actually have a failed part. This is particularly true of vehicles with the 5.3 L V-8 engines installed. However, since the website deals in older automobiles, visitors experience problems with the parts mentioned here.Ĭhevrolet Silverado pickups, Suburban and the Chevy Tahoe from 1999 through 2003 make the list of trucks that often experience air flow sensor problems. 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. See include the P0171 lean condition on bank one, and P0172 lean Of course, when the MAF sensor starts providingįalse, or out of range data the check engine light comes on.Ĭhevrolet trucks carrying a 5.3 L engine a few of the common codes you That said, there’s a few common ones found on American made automobiles with a Since the mass airflow sensor is one of the most important measuringĭevices used for mixing the air fuel mixture symptoms vary.
