Land Rover Part Number: LR126181 - Crankshaft Position Sensor
LR126181 is a crankshaft position sensor fitted in the timing gear cover area at the front of the engine. The sensor's pick-up faces the crankshaft reluctor (tone wheel) and provides a timed electrical signal the engine control unit uses to determine crankshaft angle and rotational speed, which is a primary input for ignition timing and fuel injection. Its location makes it sensitive to oil contamination and physical impact, so correct sealing and careful handling during timing cover removal are important. Typical applications include 2.0 L Ingenium four-cylinder petrol and diesel engines and 3.0 I6 timing assemblies; use the compatibility list to confirm the correct variant before ordering or installation.
