The crankshaft angle sensor is a vital electronic component in a vehicle's engine management system. It acts as the "eye" that monitors the crankshaft's movement and transmits precise data about its position and rotational speed to the electronic control unit (ECU). This data is used to precisely adjust ignition timing and fuel injection, achieving high engine efficiency and reducing harmful emissions.
Crankshaft sensor specifications:
- Country of Origin: Japan
- Product Brand: Mitsubishi
- Product Number: MR985145
- Compatible models: Mitsubishi Pajero 3500 engine
- Mitsubishi Pajero Sport 3500 engine
Main functions:
- Accurately locate the crankshaft:
- The sensor detects magnetic or optical signals (depending on the type) from the crankshaft sprocket teeth to determine its angular position.
- It sends electrical signals to the ECU to know which cylinder is in the ignition or injection phase.
- Ignition Timing:
- The control unit determines the optimal spark timing based on sensor data, preventing engine knocking.
- Fuel Injection Regulation:
- It controls the amount of fuel and the moment it is injected into the cylinders to achieve complete combustion.
- Engine Speed Monitoring (RPM):
- It helps calculate the engine revolutions per minute to display on the instrument panel and adjust the performance of other systems such as the automatic transmission.
Common symptoms of a malfunction:
- Difficulty starting or engine not starting.
- Sudden engine stop while driving.
- Engine shudder or loss of power.
- Increased fuel consumption and black smoke emission.
- The Check Engine warning light on the dashboard is on.
Product advantages:
- Rugged design: resistant to vibration, moisture and dust.
- Fast Response: Transmits real-time data to adjust engine performance.
- EASY INSTALLATION: Compatible with standard modern vehicle mountings.
comments:
- It is recommended to use an original or high-quality sensor to ensure stable and long-lasting performance.
- Verify part number compatibility with vehicle before purchase.
