Buy Motorsport Sensors in Australia
If you are looking to buy motorsport sensors in Australia, 12Volt Motorsports stocks temperature, pressure, position, speed and wideband O2 sensors from Raceworks, Bosch Motorsport, Honeywell, Variohm, Texas Instruments and Haltech. These are the sensors we fit in our own ECU installs and custom harness builds. We are based in Altona Meadows in Melbourne's western suburbs and ship Australia-wide.
Sensor Range by Type
Speccing Sensors for an ECU Install
A typical standalone ECU install runs intake air temperature, coolant temperature, MAP, oil pressure, fuel pressure, throttle position, crank and cam position and a wideband O2. Pick pressure sensor ranges to suit the job: the lowest range that covers your target reading gives the best resolution. Every sensor needs the correct mating connector, and we stock the matching OEM style and Deutsch DTM plugs so the sensor and its connector arrive together.

Wiring Sensors Properly
Run sensor circuits in 22 AWG M22759/32 Tefzel, and use M27500 shielded Tefzel for crank, cam, knock and wheel speed signals routed near ignition or high current wiring. Sleeve branches in Raychem DR25 and seal connector exits with Sumitomo W5DL. Many sensors need a 5V reference, sensor ground and signal wire, and some need pull-ups, twisted pairs or specific ECU input setup, so follow the ECU manufacturer's wiring requirements. Clean sensor wiring is the difference between stable readings and chasing phantom faults.
Frequently Asked Questions
Where can I buy motorsport sensors in Australia?
12Volt Motorsports stocks Raceworks, Bosch Motorsport, Honeywell, Variohm and Haltech sensors in Melbourne, covering temperature, pressure, position, speed and wideband O2, shipped Australia-wide.
What sensors does a standalone ECU install need?
A typical wire-in ECU install runs intake air temp, coolant temp, MAP or boost pressure, oil pressure, fuel pressure, throttle position, crank and cam position, and a wideband O2. Your tuner may add EGT, brake pressure or wheel speed depending on the build.
Should I choose a Bosch or NTK wideband sensor?
Bosch LSU sensors suit most pump fuel and E85 street and race cars. NTK sensors tolerate leaded race fuels better and are the choice for engines running leaded fuel. Both Haltech wideband kits report over CAN.
What is the difference between a 5 bar and 8 bar MAP sensor?
A 5 bar sensor reads to roughly 58 psi of boost, an 8 bar to roughly 100 psi. Pick the lowest range that covers your target boost for the best resolution.
How do I choose the right pressure sensor?
Choose on pressure range, thread type, output type, connector and your ECU input requirements. The range should suit the job: oil, fuel, brake and boost pressure all measure differently, and the lowest range that covers your target reading gives the best resolution.
Do sensors need special wiring?
Some only need basic signal wiring. Others need a 5V reference, sensor ground, pull-ups, shielded cable or twisted pair wiring, and specific ECU input configuration. Follow the ECU and sensor manufacturer requirements.
Do your sensors come with connectors?
Sensor product pages list the mating connector. We stock the matching OEM style and Deutsch connectors, so you can order the sensor and its plug together. Call us if you are unsure which plug suits.
What wire should I run to sensors?
22 AWG M22759/32 Tefzel for most sensor circuits, and M27500 shielded Tefzel for crank, cam, knock and wheel speed signals routed near ignition or high current wiring.
Do you ship sensors Australia-wide?
Yes. We ship to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between, usually same or next business day.
