Mitsubishi OEM Cam Position Sensor for Evo X (1865A066)

Firstly, Buy Mitsubishi OEM Cam Position Sensor Evo X 1865A066 online. The Mitsubishi OEM Cam Position Sensor Evo X 1865A066 is a genuine Mitsubishi factory replacement designed for the 4B11T engine in the Mitsubishi Lancer Evolution X. The camshaft position sensor is an important engine-management component that allows the ECU to monitor camshaft position and maintain proper synchronization between the engine’s mechanical timing and electronic control systems.

Part number 1865A066 is identified by Mitsubishi as an Engine Camshaft Position Sensor and is listed for the Lancer application with the 2.0L turbo engine. Evo X-specific OEM parts sources confirm that this sensor fits the 2008–2015 Mitsubishi Lancer Evolution X.

The Evo X 4B11T uses two camshaft position sensors in the cylinder head, covering the intake and exhaust camshaft positions. The 1865A066 sensor is sold individually, so one sensor is included per purchase. The replacement sensor also includes the required O-ring.

Mitsubishi OEM Cam Position Sensor Evo X 1865A066

The camshaft position sensor provides the engine control system with information about camshaft position. This information is important for engine timing and control functions, including determining the position of the camshaft relative to the crankshaft.

On the turbocharged 4B11T engine, accurate position information is essential for the ECU to manage the engine correctly. A faulty or unreliable camshaft position sensor can interfere with normal engine operation and may contribute to starting, running, or engine-management problems.

Replacing a questionable sensor with the correct genuine Mitsubishi component provides an OEM-specification solution for the Evo X.

Genuine Mitsubishi OEM Sensor

Firstly, the Mitsubishi OEM Cam Position Sensor Evo X 1865A066 is a genuine Mitsubishi component rather than a generic aftermarket replacement. Mitsubishi’s official parts catalog identifies 1865A066 as an Engine Camshaft Position Sensor and lists it as a new component with an O-ring included.

Using a genuine OEM sensor is particularly valuable on an Evo X when maintaining the factory engine-management system. The 4B11T relies on accurate sensor signals for proper electronic engine control, making the quality and compatibility of the replacement component important.

For owners restoring a factory engine, troubleshooting a sensor-related issue, or replacing an aging original sensor, 1865A066 provides the correct Mitsubishi OEM part number for the application.

Designed for the Evo X 4B11T

Secondly, this camshaft position sensor is specifically documented for the Mitsubishi Lancer Evolution X. Evo X parts specialists list 1865A066 as fitting 2008–2015 Evolution X models, while Mitsubishi’s official catalog describes the part for applications using the 2.0L turbo engine.

Nengun’s Mitsubishi OEM catalog also specifically identifies 1865A066 with the Lancer Evolution X CZ4A and 4B11T engine.

This makes the sensor an appropriate OEM replacement for Evo X engine repair, maintenance, diagnostics, and restoration.

One Sensor Per Purchase

Thirdly, the 1865A066 sensor is sold individually. Evo X-specific documentation confirms that two camshaft position sensors are used in the cylinder head, with the sensors covering the intake and exhaust camshaft positions. The product package contains one sensor and its O-ring.

If both sensors require replacement, two units should be ordered.

The mounting bolt is not part of the standard sensor package. The Evo X OEM parts listing identifies MF140205 as the applicable camshaft sensor mounting bolt.

What Does the Evo X Camshaft Position Sensor Do?

The camshaft position sensor monitors the rotational position of the camshaft and sends a corresponding signal to the engine control system. The ECU uses this information as part of its control strategy for the 4B11T engine.

Because the camshaft and crankshaft must remain synchronized, reliable position information is important for correct engine operation. A sensor that produces an inaccurate, intermittent, or missing signal can interfere with the ECU’s ability to determine the engine’s position.

That is why the camshaft position sensor should not be overlooked when diagnosing engine-management problems.

Symptoms of a Faulty Camshaft Position Sensor

A failing camshaft position sensor can potentially contribute to symptoms such as:

• Difficult starting
• Extended cranking
• Intermittent starting problems
• Engine hesitation
• Rough or inconsistent engine operation
• Reduced engine performance
• Engine-management warning lights
• Intermittent stalling
• Cam/crank synchronization-related faults

These symptoms can also be caused by other components, including crankshaft position sensors, wiring, connectors, timing components, ignition components, fuel-system problems, or ECU-related issues. Proper diagnosis should therefore be performed before replacing the sensor.

If diagnostic testing identifies a camshaft position sensor problem, replacing the affected unit with the correct OEM sensor is a sensible repair.

Why Choose a Genuine Mitsubishi Camshaft Sensor?

The Evo X 4B11T is a sophisticated turbocharged engine with electronically controlled ignition and fuel-management systems. Sensors provide the ECU with information required to control the engine.

Choosing the genuine Mitsubishi 1865A066 sensor provides several advantages:

• Genuine Mitsubishi OEM component
• Correct Evo X application
• Designed for the 4B11T engine
• Factory-specification replacement
• O-ring included
• Direct replacement for the specified OEM part number
• Suitable for maintenance and repairs
• Ideal for OEM restoration projects
• Available individually

For an Evo X owner who wants to retain the factory engine-management system, an OEM sensor is a straightforward replacement option.

Evo X Camshaft Position Sensor Installation

Before installing a replacement 1865A066, inspect the sensor connector and surrounding wiring for damage, contamination, corrosion, or loose connections. A sensor fault can sometimes be caused by an electrical or wiring issue rather than the sensor itself.

The supplied O-ring should also be inspected before installation. Since the sensor seals against the cylinder head, the sealing surface should be clean and free from debris.

The mounting bolt should be installed according to Mitsubishi’s applicable service procedure and torque specification. Avoid overtightening the sensor or mounting hardware.

If both camshaft position sensors are being replaced, replace them individually and ensure each connector is correctly installed.

1865A066 vs. Crankshaft Position Sensor

The camshaft position sensor and crankshaft position sensor perform different functions and should not be confused.

The 1865A066 is the camshaft position sensor. The Evo X crankshaft position sensor uses a different Mitsubishi part number, 1865A126. Mitsubishi’s parts catalog separately identifies these two sensors.

If an Evo X is experiencing a sensor-related fault, the diagnostic trouble code and applicable service information should be used to determine whether the camshaft or crankshaft sensor is responsible.

Buy Mitsubishi OEM Cam Position Sensor Evo X 1865A066

If you’re looking to buy Mitsubishi OEM Cam Position Sensor Evo X 1865A066, this genuine Mitsubishi sensor provides a factory replacement for the camshaft position sensing system on the 2008–2015 Evolution X 4B11T. It is sold individually with the O-ring included, making it suitable for replacing one faulty sensor or refreshing the camshaft position sensors during a larger engine service.
