Light on the dash? NCT FAIL! Turn off the light with Denso

Dashboard lights such as engine management, ABS, brake fluid and airbag will all result in an automatic NCT fail as the car is indicating there is a problem. DENSO products can help rectify these issues and turn off the warning light, helping your customers get back on the road. With rigorous testing and precision engineering, DENSO is best in class and is trusted byOE manufactures worldwide.

Possible issues causing the engine management light to appear:

Why choose DENSO Mass Air FlowSensors? ​ • ​Integrated, compact design that minimizes air pressure drop • Reduced contamination of the sensing element, increasing reliability • More accurate airflow detection • Small size passage structure that is easy to install​.

Mass airflow sensor fault​ ​The mass airflow sensor (MAF) is vital for the efficient running of an engine. In its combustion chambers, an engine burns a mixture of fuel and air. The ECU (Electronic Control Unit) uses data from the mass airflow sensor to calculate how much fuel to add to the combustion chambers to match the amount of air flowing into the engine without this information, all it can do is guess.​

Engine Overheating​ ​To avoid overheating of the engine when the engine gets extremely hot, the cooling fans keeps the engine within a safe temperature range by forcing air through the radiator.​ DENSO’s cooling fans can have solenoids fitted with sensors to ensure they only operate when needed in either low- or high- speed rotation, supporting reliable and efficient operation​. Ignition System Fault​ ​Although many people refer to the starter button or key as their car’s ignition – it’s short for ‘ignition switch’ – a car’s ignition system is far more than just how it switches on and off. The ignition system is responsible for burning or ‘igniting’ the fuel that makes an engine work.​ In a petrol car, a mixture of fuel and air, in the form of vapour, are forced into the combustion chambers, where it’s rapidly burnt in a small, controlled explosion, started by a spark. This spark is provided by a spark plug, which is a component of the ignition system.

Why choose DENSO Spark Plugs? ​

• ​Optimum performance in a compact design • Built by DENSO in-house, with ‘zero defects’ as standard​ • Designs suitable for 90% of car models • Developed in-house for a wide range of applications.​

Why choose DENSO Cooling Fans?​

• ​Developed for specific applications. • Manufactured to OE quality standards • Rigorously tested and precision-engineered​ • Designed for maximum efficiency.​
