What is a Mass Air Flow Sensor Relay?
A Mass Air Flow Sensor Relay (MAFS Relay) is an automotive component that regulates the delivery of electrical power to the mass air flow sensor in order to ensure the correct amount of air is entering the engine.
What is the purpose of a Mass Air Flow Sensor Relay?
The purpose of a MAFS Relay is to ensure the mass air flow sensor is receiving the right amount of power to accurately measure the incoming air into the engine. This, in turn, helps the engine run more efficiently and prevent engine damage.
How do I know if my Mass Air Flow Sensor Relay is faulty?
There are a few signs that may indicate your MAFS Relay is faulty. These include: decreased engine performance, engine stalling, decreased fuel economy, and the check engine light coming on.
Can a faulty Mass Air Flow Sensor Relay cause damage to my engine?
Yes, a faulty MAFS Relay can cause damage to your engine. If the relay is not providing the correct amount of power to the sensor, the wrong amount of air can enter the engine, leading to decreased performance, increased fuel consumption, and increased pollution.
How do I replace a Mass Air Flow Sensor Relay?
Replacing a MAFS Relay is a relatively simple process. Here are the steps:
- Locate the relay. It is typically located near the air filter or the intake manifold.
- Disconnect the negative battery cable.
- Unplug the harness from the relay.
- Remove the mounting screws holding the relay in place.
- Install the new relay and reattach the mounting screws.
- Reconnect the harness to the relay and the negative battery cable.
