FAQs

What is the primary function of a crankshaft sensor?

The crankshaft sensor measures the rotational speed and position of the engine's crankshaft. This information is crucial for the Engine Control Unit (ECU) to manage fuel injection and ignition timing.

Which vehicles is the Febi 28126 compatible with?

This sensor is designed for specific Alfa Romeo and Lancia models that use the OE part number 46798345.

Does this sensor come with installation instructions?

No, this product is not supplied with fitting instructions and is intended for installation by a competent individual or professional.

What are the signs of a failing crankshaft sensor?

Common signs include the Check Engine Light illuminating, the engine cranking but not starting, rough idling, stalling, and poor acceleration.

Can I install this sensor myself?

While technically possible for individuals with automotive mechanical experience and the correct tools, professional installation is recommended due to the critical nature of the part and the absence of instructions.

What does 'RPM / Crankshaft Sensor' mean?

It refers to a sensor that detects the engine's Revolutions Per Minute (RPM) by monitoring the position and speed of the crankshaft.

What is the OE number mentioned for this part?

The Original Equipment (OE) number associated with this Febi 28126 sensor is 46798345.

Troubleshooting

Check Engine Light is on

A common cause for the Check Engine Light is a faulty crankshaft sensor. This sensor's readings are vital for engine operation, and deviations can trigger the light. Consult a diagnostic tool for specific error codes.

Engine cranks but won't start

A failed crankshaft sensor can prevent the engine from starting because the ECU does not receive the necessary data about crankshaft position to time fuel injection and ignition.

Rough idling or stalling

Inconsistent or lost signals from the crankshaft sensor can cause irregular engine operation, leading to a rough idle or the engine stalling unexpectedly.

Poor acceleration or engine performance

If the sensor provides inaccurate data, the ECU may miscalculate fuel and ignition timing, resulting in reduced power and poor acceleration.

Setup, Compatibility & Care

Compatibility: This Febi RPM / Crankshaft Sensor 28126 is specifically designed for certain Alfa Romeo and Lancia models that use the OE number 46798345. Always verify your vehicle's existing part number or consult a professional to confirm compatibility before purchase.

Setup: Installation of a crankshaft sensor requires mechanical knowledge and specific tools. It is typically located near the crankshaft pulley, often at the front or rear of the engine block. The sensor needs to be securely fastened to the engine block, and its electrical connector must be properly attached. Due to the critical nature of this component and the lack of included instructions, professional installation by a qualified mechanic is strongly recommended.

Care: Once installed, the crankshaft sensor requires no regular maintenance. However, it is important to keep the engine bay clean and free from excessive dirt and debris, which could potentially interfere with the sensor or its wiring.
