Camshaft Position Sensor > MAZDA 3 / 5 / 6 / CX-7 / MX-5 MIATA 2.0L / 2.3L / 2.5L MZR/L-Series ENGINE > L3G2-18-230 | GENUINE PART (Mazda Original Equipment)

This is a Genuine OEM Camshaft Position Sensor (CMP Sensor), identified by the Mazda part number L3G2-18-230. This sensor is a factory-original component designed for the family of Mazda's popular MZR/L-Series 4-cylinder gasoline engines, which powered many of their mid-sized vehicles.

The sensor is critical for the reliable operation of these engines, particularly in models featuring Variable Valve Timing (VVT):

VVT Control: In VVT-equipped engines, this sensor provides the ECM with the necessary rotational data to precisely adjust the intake and/or exhaust valve timing for optimal power and efficiency across all RPM ranges.
Timing Reference: It maintains the correct phase relationship between the camshaft and the crankshaft, ensuring the ignition and fuel injectors fire at the exact required moment.
Fitment Assurance: The part number L3G2-18-230 is a confirmed genuine part for the listed engine applications within the specified model years, particularly the non-turbo 2.0L, 2.3L, and 2.5L engines. Please note that the fitment for the Mazda 8 (often called MPV) varies by region and engine type, so a VIN check is recommended for that specific model.

Using the Genuine Part (L3G2-18-230) ensures:

Precise Signal Accuracy: Essential for the sensitive VVT and electronic engine management systems.
Guaranteed Fitment and Durability: Designed to meet the stringent quality standards of Mazda for long service life.
