Sensors, Electrical Components and Controllers for Diesel Systems
Browse our selection of Sensors, Electrical components, and Controllers for modern diesel systems. These components monitor vital statistics such as rail pressure, air intake, and crankshaft position to provide your Electronic Control Unit (ECU) with the data needed to make micro-second adjustments.
A faulty sensor or a failing solenoid can mimic major mechanical failures, often resulting in “limp mode,” poor fuel economy, or a refusal to start. Whether it’s a Rail Pressure Sensor maintaining the equilibrium of a common rail system, or a Stop Solenoid providing a reliable fuel cut-off for a mechanical pump, these electrical components ensure that your engine operates within safe and efficient parameters. Using high-quality, genuine parts is the only way to ensure the data sent to your engine’s ECU is accurate and reliable.
At Cairns Diesel Service, we provide the technical-grade electrical components required for a diverse range of light vehicle, heavy transport, and industrial diesel engines.

Our comprehensive selection of Sensors, Electrical components, and Controllers includes:

Engine Management Sensors: We stock critical data-gathering components, including Rail Pressure Sensors for the Toyota 1KD, Cam and Crank Position Sensors for Hino, Mitsubishi, and Isuzu, and high-temp Exhaust Temperature Sensors.

Air Flow & Emissions: Featuring AFI and Bosch Air Mass Meters (Air Flow Sensors) and Oxygen (Lambda) Sensors to maintain correct air-fuel ratios and emission standards.

Control Units & Drivers: We supply specialised electronics such as Genuine Toyota Injector Drivers for Land Cruiser and Hilux (1KD/2KD) models, essential for the high-voltage operation of common rail injectors.

Solenoids & Fuel Control: A wide range of 12V and 24V Stop Solenoids from Bosch and Delphi, supporting everything from Perkins industrial engines to Denso and Bosch VE-type mechanical pumps.

Monitoring & Feedback: Including fuel tank sender units for the Hilux and speed sensors for specialised injector pumps like the Mitsubishi VRZ.

We proudly supply genuine electronics from the world’s leading diesel innovators, including Bosch, Denso, Delphi, AFI, and Toyota. Trust the experts at Cairns Diesel Service to provide the precise electrical components you need to restore communication and control to your diesel engine.
