Dealing with a check engine light for a knock sensor code on your GM truck or SUV? This WMPHE kit has everything you need: two new knock sensors and a new wiring harness. The sensors are made from a durable alloy with a heat-resistant coating, and the harness is ABS plastic—both designed to withstand engine bay heat and last. This set replaces common OEM part numbers 12601822, 12589867, 12597415, and others. It fits a massive list of GM vehicles from 1999 to 2007, including: Chevy Silverado 1500/2500/3500, Avalanche, Suburban, Tahoe, Express vans; GMC Sierra 1500/2500/3500, Yukon, Savana; Cadillac Escalade; Hummer H2; and more with popular engines like the 4.8L, 5.3L, and 6.0L V8s. Always verify your exact year, model, and engine. Installation involves locating the old sensors on the engine valley under the intake manifold (a common job on these motors), unplugging the harness, and replacing them. The new harness ensures good connections and prevents future corrosion issues. A complete, quality repair kit to fix misfire codes and restore engine performance.
