⁉️ Why won't the car start? This video describes the operation of the crankshaft position sensor, how to check it, and types of malfunctions. How does the crankshaft position sensor work? The crankshaft position sensor is positioned so that the teeth on the pulley attached to the crankshaft pass near the tip of the sensor. The pulley is missing one or more teeth to provide the ECU with a reference point for the crankshaft position. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 👉 Blog for car enthusiasts - https://blogproavto.ru 🖥 Video on lambda probe diagnostics - • Lambda probe - checking the sensor and rem... 💻 MAF diagnostics - • Mass air flow sensor MAF.... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ⁉️ As the crankshaft rotates, the sensor produces a pulsed voltage signal, where each pulse corresponds to a tooth on the pulley The ECU uses the signal from the crankshaft position sensor to determine when to produce a spark and in which cylinder. 👉 The signal from the crankshaft position is also used to monitor misfires in any of the cylinders. 👎 If there is no signal from the sensor, there will be no spark and the fuel injectors will not work. ✍️ A faulty crankshaft sensor can cause intermittent problems: the car may randomly shut off or stall, but then restart without problems. The engine may have trouble starting in wet weather, but then start normally. ☝Sometimes you may see that the crankshaft position sensor behaves erratically. - ... ECM Malfunction P0337 - Crankshaft Position Sensor "A" - Low Input Crankshaft position sensor malfunction Incorrect installation of the crankshaft position sensor Starter malfunction or low battery voltage An electrical fault is present (such as a short circuit) P0338 - Crankshaft Position Sensor "A" - High Input The most common causes of the P0338 code are: Damaged crankshaft position sensor Damaged crankshaft position sensor connector Damaged crankshaft position sensor wiring Damaged gear Damaged timing belt In rare cases, a malfunction of the powertrain control module (PCM) P0339 - Crankshaft Position Sensor "A" Circuit Intermittent Malfunction of the crankshaft position sensor Damaged crankshaft position sensor electrical connector Damaged crankshaft position sensor wiring Damaged Gear Worn or damaged timing belt In rare cases, PCM malfunction P0340 - Camshaft Position Sensor "A" Bank 1 - Circuit Malfunction Shorted, corroded, or damaged in the camshaft position sensor wires Shorted, corroded, or damaged in the camshaft position sensor connector Malfunction of the camshaft position sensor Malfunction of the crankshaft position sensor PCM malfunction P0341 - Camshaft Position Sensor "A" Bank 1 - Range/Performance Code P0341 is stored in the ECM memory and the Check Engine indicator on the instrument cluster illuminates. Loss of power and engine stalling. Misfires in cylinders and rough engine operation. Problems with starting the engine.
