2021 Volkswagen Jetta Engine Sensors, Relays, Switches

Volkswagen has always been known for its innovative and fuel-efficient engines, both gasoline and diesel ones, which have been used by many VW brands including Porsche and Audi. Actually, Volkswagen is one of the first companies that started a common tendency to decrease engine displacement with the addition of a turbocharger and direct injection. Such an approach allows for achieving higher performance, better fuel economy, and lower emissions; however, motors became much more complex and require more careful servicing. In order to ensure the smooth operation of such an engine, all of its sensors and switches have to be in perfect working condition, and some of them may need attention sooner than expected.

The main sensors of your 2021 Volkswagen Jetta responsible for accurate engine work are crankshaft and camshaft position sensors – their impulses enable the ECU to ensure proper injection and ignition. When any of them is faulty, the engine won't even start, so these parts have to be utterly reliable and durable. But unfortunately, nothing is immune to malfunctions. In our assortment of 2021 Volkswagen Jetta engine sensors, relays, switches, and some other components, you will find both the original and aftermarket products sourced from reputable manufacturers.
