Without a crankshaft pulse sensor, the engine management system has no way of knowing where in its rotation the crankshaft sits at any given moment โ and without that reference, it cannot time fuel injection or ignition events. The sensor reads a toothed reluctor ring mounted on the crankshaft and sends a series of pulses to the ECU that allow it to calculate both rotational speed and absolute position with sub-millisecond precision. When the sensor begins to fail, the symptoms can be intermittent at first: a random misfire at idle, hesitation during warm-up, or an occasional stall that restores itself once the sensor cools down. In more advanced failure the engine refuses to start at all, because without a valid crank signal the ECU will not enable the injection system. ERA and MEAT & DORIA supply crankshaft sensors across a wide range of European applications, including Renault, Opel, and Volkswagen platforms where this sensor type is especially common. Because the OE number specifies the signal type (inductive vs Hall-effect), connector pinout, and mounting bracket geometry, substituting a non-matching part risks triggering fault codes even if the unit physically bolts on. Replacing a failing crank sensor is one of the more cost-effective diagnostic interventions on a misfiring engine.
Use the make-model-engine selector or your VIN to narrow down the listings on this page, then check the OE number against any part numbers visible on your existing sensor body or in your vehicle's service history. The sensor signal type โ inductive or Hall-effect โ and its connector pattern are encoded in the OE reference and are not interchangeable. Using the wrong type will trigger a persistent ECU fault even if the sensor physically fits the mounting bracket.
OEM crankshaft sensors are calibrated to produce the precise pulse waveform the ECU expects for injection and ignition timing. Quality aftermarket suppliers such as ERA and MEAT & DORIA manufacture sensors to equivalent signal specifications and include the appropriate wiring connector. Budget alternatives occasionally produce subtly incorrect signal edges that cause intermittent misfires difficult to diagnose, since the fault may not trigger a stored code consistently.
Yes โ this is one of the most common causes of a no-crank or crank-no-start fault on modern injection engines. The ECU requires a valid crankshaft position signal before it will enable the fuel injectors or ignition coils, so a fully failed sensor prevents the engine from firing at all. Partial failures often present first as intermittent stalling when hot, because the sensor's internal resistance rises with temperature and the signal drops below the ECU's threshold.
Early symptoms include random misfires at idle with no apparent pattern, difficult hot-starts where the engine cranks but takes longer than usual to fire, and occasional stalls at low speed that resolve once the car cools. A check engine light with a stored P0335 or similar crank position sensor code is a direct indicator. In some cases fuel consumption rises as the ECU falls back to a conservative injection map while the sensor signal is intermittent.
