Types of Mitsubishi speed sensors

A Mitsubishi speed sensor is an essential component in a vehicle's engine control unit, as it helps monitor the speed of the vehicle. There are different types of speed sensors, including:

• Wheel speed sensor

The wheel speed sensor is used for monitoring the speed of the wheels. It does this by measuring the revolution speed of the wheel. The information on the wheel speed is sent to the ABS system, traction control, and the engine control unit. The ABS system uses this information to regulate the breaking, while the ECU uses it to control the engine functions. The evo x wheel speed sensor is an example of this type.

• Transmission speed sensor

As the name implies, the transmission speed sensor is used for monitoring the speed of the transmission shaft. The sensor is mounted on the transmission case in such a way that it detects the rotation of the selected shaft. A malfunctioning sensor may trigger codes like mitsubishi p0715.

• Vehicle speed sensor

The vehicle speed sensor, also known as the VSS, is a pulse generator that is used for measuring the speed of the vehicle. The VSS can either be analog or digital. The analog VSS generates a voltage signal that is proportional to the speed of the vehicle, while the digital VSS generates a square wave signal of 0-5V or 0-12V. If you experience issues with your 3000gt speed sensor, it might be time for a replacement.

• ABS speed sensor

The ABS speed sensor is used to measure the rotational speed of the wheels. The sensor is usually installed at each of the wheels near the ABS ring for monitoring the speed of the wheel. It helps to prevent the wheels from locking up during emergency braking. For instance, the abs sensor mitsubishi outlander plays a crucial role in this system.

• Crankshaft position sensor

The crankshaft position sensor is responsible for monitoring the position and speed of the crankshaft. It does this by sending a signal to the ECU, which, in turn, adjusts the ignition timing and fuel injection timing. Due to this, the engine runs smoothly.

Specification and Maintenance of Mitsubishi Speed Sensor

Understanding the specifications and maintenance requirements of Mitsubishi speed sensors is crucial to ensuring optimal performance and longevity. Here are some key specifications and maintenance guidelines:

• Specifications

Mounting style: Different types of mounting styles are available. The compatibility and mounting method depend on the model of the vehicle. The mounting styles include bolt-on, screw-in, or push-in. The mounting method ensures that the sensor is securely attached to the transmission.

Number of wires: The Mitsubishi vehicle speed sensor has different numbers of wires to connect to the vehicle's ECU. The wires have different functions. Some wires provide power to the sensor, while others are for signal transmission. Most sensors have three wires: one for power, one for ground, and one for signal. The three-wire connection provides accurate speed information to the ECU.

Connector type: The connector type ensures compatibility with the vehicle's wiring harness. The most common connector type is the plug-and-play connector. It enables quick and easy installation without any modifications to the wiring harness.

Output signal: The output signal provides information about the speed of the vehicle. The most common output signal is the square wave signal. It has a voltage level of 5V and a frequency proportional to the speed of the vehicle. The signal is compatible with the ECU's input signal and provides accurate speed information to the ECU.

Operating temperature: The operating temperature is the temperature range within which the sensor can operate effectively. The operating temperature of most sensors is between -40°C and 120°C. It allows the sensor to operate in extreme temperature conditions without malfunctioning.

Material: The sensor's material is the substance used to construct the sensor. The sensor is made of durable and heat-resistant materials, such as plastic and metal, to protect it from the extreme heat generated by the transmission.

• Maintenance

Regular inspection: Regular inspection of the speed sensor and its wiring harness is essential. Check for signs of damage, such as cracks, fraying, or corrosion. Address any issues that may affect the sensor's performance.

Check the sensor's mounting: Check the sensor's mounting to the transmission. Ensure that it is securely attached and undamaged. Loose or improperly mounted sensors can cause inaccurate speed readings. Also, check the sensor's gear and ensure that it is in good condition and properly connected to the transmission.

Clean the sensor: Cleaning the sensor is essential to remove any dirt, debris, or buildup that may affect its performance. Use a soft brush or cloth to gently clean the sensor and the area around it. Avoid using harsh chemicals or high-pressure water, as this may damage the sensor.

Check the sensor's wiring: Check the sensor's wiring connection to the vehicle's ECU. Ensure that the wiring is not damaged, loose, or corroded. Address any issues that may affect the signal transmission. Also, check the sensor's wiring for interference from other electronic components that may affect the signal quality. Address any interference issues by adjusting the sensor's wiring.

Seal the sensor: Sealing the sensor with a waterproof sealant protects it from water, dirt, and debris. Apply the sealant around the sensor's connection to the transmission. Ensure that the sealant is completely dry before operating the vehicle.

Follow the manufacturer's instructions: Follow the manufacturer's maintenance instructions for the speed sensor. This ensures that the sensor continues to provide accurate speed information for the vehicle.

How to Choose Mitsubishi Speed Sensor

• Understanding the Needs

Consider the vehicle's specific needs and the sort of issues that are being experienced. If there is a consistency in problems related to speed, the speed sensor might be the right choice.

• Determine Compatibility

Ensure that the speed sensor is compatible with the vehicle's make, model, and year. Double-check the specifications to be sure that the correct sensor is selected.

• Assess Quality

When shopping for a new speed sensor, quality is always important. Be sure to research the manufacturer and read reviews to be sure the product is dependable.

• Choose Between OEM and Aftermarket

Decide if it is more important to stay with the original equipment manufacturer's parts or if an aftermarket part will suffice. Aftermarket parts can be more affordable and provide better performance.

• Consider the Sensor Type

Determine if a Mitsubishi ABS speed sensor or another type is needed. For instance, a Hall Effect sensor can be used to measure speed and position. A variable reluctance sensor is another option. It is important to choose the correct type for the vehicle.

• Check Warranty and Return Policy

Check that the speed sensor is covered by a good warranty. Be sure the warranty is sufficient and that the return policy is fair. These will protect the investment.

• Consult a Professional

If overwhelmed by the options or unsure of the correct decision, consider consulting a professional mechanic. A mechanic can provide advice and may also install the speed sensor if necessary.

• Price

Consider the benefits of spending a little more to get a better quality sensor. Cheaper is not always a better deal in the long run.

• Read Reviews

Look for reviews from other customers on the product in which there is an interest. This can help provide an idea of how it performs over the long term.

• Check for Counterfeit Products

Be wary of counterfeit products. Check that the speed sensor is genuine by buying directly from the manufacturer or an authorized dealer.
