Sensors and switches

The technological core of the brand: ignition coils, EGR valves, throttle bodies, sensors and switches that let the engine and vehicle systems measure and react in real time. Every unit is calibrated for accurate signal output across the full temperature and vibration range.

The full VOLTREK range of sensors, switches, coils and EGR valves

Product types

  • VOLTREK three-output ignition coil

    Ignition coil

    VOLTREK ignition coils step the battery voltage up to the high voltage the spark plug needs to ignite the mixture in petrol engines.

  • VOLTREK EGR valve and EGR cooler

    EGR valve and EGR cooler

    VOLTREK EGR valves and coolers route part of the exhaust gas back into the intake to lower combustion temperature and NOx emissions.

  • VOLTREK electronic throttle body

    Throttle body

    The VOLTREK throttle body meters the air entering the engine according to the pedal and the engine control unit.

  • VOLTREK throttle position sensor

    Throttle position sensor (TPS)

    The VOLTREK throttle position sensor reports throttle-plate opening to the control unit for accurate response and optimal consumption.

  • VOLTREK NOx sensor with control module and harness

    NOx sensor

    The VOLTREK NOx sensor measures nitrogen-oxide concentration in the exhaust so the engine and the SCR system can keep emissions within limits.

  • VOLTREK pressure sensor

    Pressure sensor

    VOLTREK pressure sensors measure air, fuel or oil pressure and report it to the control unit for accurate metering and protection.

  • VOLTREK steering column switch with indicator and wiper stalks

    Steering column switch

    The VOLTREK steering column switch controls indicators, lights, wipers and other functions from the stalks behind the wheel.

  • Various VOLTREK switches: pressure switch, thermal switch and brake switch

    Various switches

    VOLTREK control, function and auxiliary switches: oil pressure switches, brake light switches, thermal switches and door switches.

  • VOLTREK coolant temperature sensor

    Temperature sensor

    VOLTREK temperature sensors measure coolant, oil, air and exhaust temperature for accurate engine control.

  • VOLTREK crankshaft sensor with cable and connector

    Crankshaft and camshaft sensor

    VOLTREK crankshaft and camshaft sensors give the control unit engine position and speed for correctly timed ignition and injection.

  • VOLTREK air flow sensor with housing

    Air flow sensor (MAF / MAP)

    VOLTREK air flow sensors measure the mass or pressure of the air entering the engine for accurate fuel metering.

  • VOLTREK ABS sensor with cable

    ABS and speed sensor

    VOLTREK ABS and speed sensors measure wheel and transmission rotation for safe braking and an accurate speedometer.

  • VOLTREK lambda sensor with cable and connector

    Lambda and level sensor

    The VOLTREK lambda sensor measures exhaust oxygen for an optimal mixture; level sensors monitor oil and fluid levels.
