What does a knock sensor do?
The knock sensor is located on the outside of the engine block. Its job is to record knocking noise from the engine in order to prevent engine damage.
The knock sensor "listens out for" vibrations from the engine block and converts these into electrical signals. The signals are filtered and evaluated in the engine’s control unit. If the vibrations are determined to be outside of the predefined ‘normal’ limits, the engine management control unit will alter the ignition timing until it returns to within the correct limits.
Dacia
Dacia is a Romanian automobile manufacturer, established over 50 years ago in 1966, and has been a subsidiary of the French car manufacturer Renault since 1999.
Dacia is Romania’s top company by revenue and the largest exporter, constituting 7.3% of the country’s total exports in 2014.
###How popular is Dacia in the United Kingdom? Dacia offers great value budget motoring—but don’t think just because they’re cheap they’re not worth the money. The Sandero hatchback is Britain’s cheapest new car and has been receiving high praise from many of the critics and car reviewers throughout the country.
There are currently 137k Dacia vehicles on the roads in the UK, but that number is showing steady, solid growth year by year. Having only been introduced into the UK market in 2013, and with the popularity growing through their more than affordable yet reliable cars, it’s looking like they’re only heading from strength to strength.
###Superb value city cars, MPVs and SUVs With a neat but tidy range featuring the Logan estate, the Sandero hatchback, the Duster SUV and the Lodgy MPV, Dacia looks to be aiming primarily towards budget conscious family drivers.
Yet with the provision of new technologies, the model platforms and the support of Renault behind them, they’re in a great position to offer not only the low prices they’re renowned for but with real substance to back them up.
###Dacia: Don’t let the UK numbers fool you Despite being a relative newcomer to the UK market, Dacia has been manufacturing and selling cars around the world for a lot longer than they have here. The global success of this Romanian marque stands at over 4.5m units sold worldwide since the Renault supported relaunch in 2004. It became the fastest growing retail brand in Europe in 2017, with sales of the Sandero rising by 16%, and selling almost 200k units.
How often should a knock sensor need replacing?
Replacing a knock sensor is not part of routine car maintenance so should only need to be fixed when it breaks or begins to fail. On most modern vehicles, the knock sensor should last over 150,000 miles or the lifetime of the vehicle.
The law, vehicle regulations and your MOT
A fault with the knock sensor will often illuminate the Engine Management Light in your car. Your vehicle will fail its MOT if your Engine Management Light remains on when the engine has been started. Under the new MOT rules, it is now classed as a major fault so will need to be fixed before a mechanic can pass your car. Therefore it’s crucial that you keep an eye out for engine warning lights and have your car inspected by one of our vetted mechanics when necessary.
