Jeep Grand Cherokee Ignition Relays, Sensors & Switches

Elegant and impressive, the Jeep Grand Cherokee was introduced to the American market in 1992. Popular among both the public and automotive press, the vehicle proved to be a top seller: some 2.7 million units were sold in the US and Canada from 2000 to 2015. Featuring a unibody chassis and independent suspension, the Grand Cherokee is praised for its safety, precise steering, and comfortable ride. The model can handle virtually any terrain: its off-road capabilities are just unsurpassed. Powered by a variety of large engines, the Grand Cherokee is equipped with an automatic eight-speed transmission.

Normally, the air-fuel mixture is ignited when it is fully compressed; sometimes, however, the mixture detonates when the piston is not in the right position. This situation is known as ‘knocking’ or detonation: it can lead to irreparable damage to the engine. As soon as the knock sensor detects detonation, the ECU automatically adjusts ignition timing until the sensor stops determining detonation. There are also other devices like an ignition switch, which starts and stops operation of the vehicle’s electrical system, ignition modules, and so on. We offer you Jeep Grand Cherokee ignition switches and ignition knock sensors that were manufactured by renowned aftermarket companies such as Dorman, Crown, Standard, ARC, and Beck Arnley.
