If your sensor is faulty or contaminated, often due to dirty or over oiled air filters, you might notice issues like P0101 codes, a rough idle, poor fuel economy, or sluggish performance. Built to meet or exceed OEM standards, the Alliant Power MAF Sensor delivers the reliability and durability you need to get your Duramax back to peak performance.
