Bosch MAF Sensor - Monitors and controls air/fuel ratios

Your car's air flow sensor or MAF sensor is tasked with determining the flow rate of air entering a fuel injected car. When the ECU knows how much air is entering the engine, it is able to supply the correct amount of fuel for the car to run correctly.

Bringing together comprehensive expertise in vehicle technology and hardware, Bosch paves the way when it comes to switches, sensors and engine management. With impressive quality and reliability, Bosch incorporate the latest technology into their state-of-the-art range of switches and sensors inspiring confidence in drivers who use their products that their vehicles will continue to run properly and efficiently again and again. With a reputation for OEM production, Bosch switches and sensors are built to match or exceed the quality and performance of some factory-fitted pieces meaning you can rely on them to do their job while you focus on driving. Just some of the switches and sensors which Bosch offer include:

  • Oxygen sensors
  • Crankshaft sensors
  • Camshaft sensors
  • Fuel pressor sensors
  • MAP sensors
  • Fuel pressure sensors

Gone are the days of carburettors and points ignition, when it comes to running modern cars pretty much everything is electronically calculated, adjusted, transmitted and actuated by your ECU (Engine Control Unit) or ECM (Engine Control Module). Whilst the ECU is able to do all the clever calculations and literally operate your car, it relies on a myriad of switches and sensors to transmit all of the necessary information it requires in order to allow the ECU to do its job including oil pressure, fuel pressure, coolant temperature, A/C pressure, power steering pressure and even fuel temperature. Behaving as your car's nervous system, faults in automotive switches or sensors can cause issues such as a lack of power, poor efficiency, overheating, internal engine damage or a car that won't run, start or idle at all. Whilst your switches and sensors will take care of engine vitals such as oil pressure indication, coolant temperature and oil temperature, various switches and sensors also allow the operation of some of the extra features you wouldn't want to be without including air conditioning systems, electric windows and even interior lights.

Subjected to harsh under-bonnet conditions and tough road use, just like other components of your car, old switches and sensors can fail over time and give incorrect data or no data at all to the ECU. Often these issues will flag up a check engine light on the car which is handy if you have a code reader, however sometimes the issue will remain a mystery. We recommend testing your suspect sensors with a multi-meter to track down the issue. By testing for continuity, voltage and resistance, you can confirm the issue and get stuck into fitting a replacement sensor. By fitting quality replacement switches and sensors to your car, you can drive with the confidence that your car will run to its maximum potential in terms of power, efficiency and longevity and that all of your car's features will continue to operate correctly for time to come. If you're replacing a sensor or switch, shop our whole range on the Repco website or visit your nearest Repco store and speak with one of our team.
