Lotus Elise Mass airflow sensor replacement
Is it time to replace your Lotus Elise mass airflow sensor?
When your Lotus Elise has been driving like a dream but suddenly starts driving like a dog, it could be the mass airflow sensor (MAF sensor) or airflow meter. This little device will certainly let you know when it decides not to play ‘happy cars’ anymore.
You’re sure to notice when the MAF sensor fails or is on its way out on your Lotus Elise. And you’ll be looking to renew it quick smart.
The sensor is an electrical device that plugs into the Lotus Elise and is typically situated between the air filter and engine intake manifold.
The MAF sensor measures the air that travels through the air cleaner and into the throttle body. That information is sent to the vehicle’s computer (ECU), which then works to provide the correct air-fuel mixture to the engine to ensure optimal combustion and effective engine management.
The sensor will be either a hot-wire or hot-film type. A constantly heated wire or membrane within the sensor responds to the air flowing over it by cooling down or as the airflow lessens by warming up. This signals to the Lotus Elise's ECU how much air is flowing and it responds accordingly.
The air that flows into the engine comes from the exterior of the car. This does mean that various contaminants - such as dust and debris - can enter the sensor. While the air filter is designed to stop these contaminants, some may get through and impact the MAF sensor and over time it can collect dirt or simply fail through wear and tear.
Here are some signs your mass flow sensor might need replacing:
- Check engine light is on
- Car lazy on acceleration
- Rough engine
- Increased fuel consumption
- Car runs better when the MAF sensor is disconnected
- Lack of engine power
- Engine surge at idle
- Data diagnostic points to MAF sensor
- Sensor fails to respond to signal
The symptoms of a faulty MAF sensor can be similar to various other issues. Check the sensor is receiving power and a signal before considering having it replaced.
Have the MAF sensor checked and replaced as soon as possible if you're noticing the symptoms. A rough running engine will eventually cause damage and other issues.
It is important to ensure the Lotus Elise's engine is functioning correctly to optimise output and performance and reduce instances of failure.
The MAF sensor is important in creating the conditions to provide the cleanest and most efficient ignition in the combustion chamber. It is advised to replace the MAF sensor as soon as there is a failure detected.
