One Stop Purchase Pulse Sensor 038907319F for Jetta

This pulse sensor OE 038907319F is an essential electronic component specially produced for Jetta models. It is also known as crankshaft position sensor, responsible for detecting the real-time rotational speed and crankshaft angle position of the engine crankshaft while the vehicle is running. It converts mechanical rotation signals into accurate electrical signals and transmits these data to the engine control unit. The ECU relies on this information to adjust fuel injection timing and ignition timing precisely, which directly affects engine starting performance, idle stability and power output. Adopting high-quality internal sensing chip and reinforced sealing housing, this pulse sensor features excellent vibration resistance, high temperature resistance and anti-interference ability. It can operate reliably in the harsh high-temperature and high-vibration environment inside the engine bay and resist electromagnetic interference from other on-board electrical parts. Each finished sensor will pass strict signal detection, high-low temperature aging test and waterproof sealing inspection before shipment. Once the pulse sensor becomes worn out or fails, the vehicle may show symptoms such as hard starting, sudden stalling during driving, unstable idling, loss of engine power and illuminated engine warning light on dashboard. Delayed replacement may lead to vehicle breakdown on road and secondary damage to related engine parts. This premium aftermarket pulse sensor fully matches original installation size and electrical parameters, simple to mount without extra modification. It can restore accurate signal feedback of engine crankshaft system, help the engine work smoothly and keep fuel consumption at normal level, serving as a reliable replacement solution for Jetta maintenance and repair.
