Engine Sensors for Cars

Engine Sensors

The Rise of Engine Sensors

New vehicles are increasingly equipped with more engine sensors, sometimes more than 100 sensors per vehicle in high-end cars – and that trend looks set to continue.
Valeo has been a global powertrain sensors specialist for more than 40 years. They bring that experience and expertise to the independent aftermarket with an Original Equipment (OE) quality range of engine sensors.

 

A Continuous Range Extension

Over 1100 references are currently available for the 11 types of engine sensors , including mass air flow meter sensors (MAF), air intake temperature sensors, temperature manifold air pressure sensors (TMAP), camshaft sensors, knock sensors, crankshaft sensors, speedometer sensors, oil pressure sensors, oil level sensors, oxygen sensors, exhaust gas temperature sensors.

Valeo continues to extend its engine sensors range to offer a one-stop-shop purchasing experience.

 

Added Value

Speed Sensor

What is A Speed Sensor?

The speed sensor contains a pulse generator that converts the mechanical rotating movement into an electric signal to the speedometer through the Electrical Control Unit (ECU). This is mechanically driven from the gearbox in vehicles without ABS (before 2004). Inside the gearbox, the output shaft contains a gear wheel which rotates with the shaft. Linked to this gear wheel, and driven by it, is a small pinion gear, speedometer drive pinion.

 

Oxygen Sensor

What is An Oxygen Sensor?

Oxygen sensors, also known as Lambda sensors, are critically important for your vehicle. They work by comparing measurements of the remaining oxygen concentration in the exhaust gases and the oxygen content in the ambient air. They are the most effective way to monitor and regulate the combustion process. They control the air-fuel mixture ratio and ensure that the engine works at the optimum level.

 

Mass Airflow Meter

What Is a Mass Airflow Meter?

The Mass Airflow Meter measures the air density flowing into the vehicle’s air intake. The information provided helps the ECU deliver the proper mix of air-fuel mixture to the engine and the spark timing. The MAF measures the volume of air and compensates for its density.

 

Camshaft Sensor

What is A Camshaft Sensor?

The camshaft sensor monitors the engine speed and valve position and determines which cylinder is firing to synchronize the injector and the coil firing sequence. It sends signals to the Engine Control Module (ECM) to control the fuel injection, ignition timing and other functions. The camshaft sensor is essential for maintaining correct engine timing and proper engine function.

 

Crankshaft Sensor

What is A Crankshaft Sensor?

The crankshaft sensor detects the rotation speed and position of the crankshaft. This sensor sends information to the ECU to control the timing of fuel injection and the ignition system. It measures the RPM speed and is often mounted near the flywheel, which is a rotating TDC target (top dead centre.)

 

Oil Pressure Sensor

What is An Oil Pressure Sensor?

The oil pressure sensor measures the oil pressure in the sump and delivers the data to the ECU and the engine oil pressure gauge. In case of low engine oil pressure, the ECU will inform the driver and adopt control measures automatically to protect the engine.

 

Air Intake Temperature Sensor

What is An Air Intake Temperature Sensor?

The air-intake temperature sensor is mounted on the air intake manifold, detecting the mass airflow and sending a signal to the ECU. It detects boosts in air temperature by working in two stages with the mass airflow sensor, which also includes a temperature sensor.

 

Knock Sensor

What is A Knock Sensor?

The knock sensor detects the engine noises through different frequencies and sends a signal to the ECU. The ECU uses this information to limit the spark advance to prevent detonation from occurring. Every vehicle is equipped with a knock sensor for the control unit to the ignition system to anticipate a knock or detonation.

 

TMAP Sensor

What is A TMAP Sensor?

The temperature manifold air pressure sensor (TMAP sensor) detects the mass airflow and the pressure and sends this information as a signal to the ECU.

 

Oil Level Sensor

What is An Oil Level Sensor?

The oil level sensor ensures that the engine oil level does not become dangerously low without being noticed, which could cause damage to the engine. It can measure the oil level continuously, both in the dynamic and static range.

 

Exhaust gas temperature sensor (EGT) 

What is an exhaust gas temperature sensor (EGT)?  

According to the Euro Standard the exhaust system now has many parts which act on the reduction of a vehicle’s pollutant emissions. 

The Exhaust Gas Temperature Sensor is one of them.

This sensor, used on both petrol and diesel engines, measures the temperature of the exhaust gas and sends this information to the ECU as a voltage signal to regulate engine conditions and effectively reduce emissions.
