Camshaft Position Sensor > MAZDA 2 (DE) & MAZDA 3 (BK) 1.3L / 1.5L / 1.6L GASOLINE ENGINE > ZJ01-18-230 | GENUINE PART (Mazda Original Equipment)

This is a Genuine OEM Camshaft Position Sensor (CMP Sensor), identified by the Mazda part number ZJ01-18-230. This part is the factory-original sensor designed for the popular 1.3L, 1.5L, and 1.6L gasoline engines used in the earlier generations of the Mazda 2 and Mazda 3.

 
 
The sensor is essential for engine management:

Timing Reference: It monitors the camshaft's position and speed, sending a signal to the ECM.
Sequential Operation: The ECM uses this signal to perfectly synchronize the firing of the spark plugs and the injection of fuel (sequential fuel injection), which is necessary for efficient combustion and smooth engine operation.
Fitment Assurance: The part number ZJ01-18-230 is consistently verified as the correct genuine Camshaft Position Sensor for the 1.5L Mazda 2 (DE chassis) and the 1.6L Mazda 3 (BK chassis) for the specified model years.

Using the Genuine Part (ZJ01-18-230) ensures:

Precise Signal Accuracy: Required by the ECM for accurate engine timing. Inaccurate signals often cause P0340/P0341 fault codes.
Guaranteed Fitment and Durability: Provides the correct fitment, connector, and reliable performance necessary for this specific engine platform.
