How to replace the mass air flow sensor?
Here is the tsb on replacing the Mass Air flow sensor. You only have to reprogram the computer if necessary. Here is the instructions. See for yourself. 1. Remove the air filter element. Then, vacuum out all dust/dirt/debris found inside both halves of the air filter housing.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
What are the symptoms of a bad air flow sensor?
The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.
How does the MAF sensor work on a Trafic?
The MAF (mass airflow) sensor basically measures the amount of air that is going into the engine. It then feeds this information to the ECU, which decides how much fuel it’s going to then deliver to the engine.

Where is the MAF sensor on a Trafic Vivaro?
The MAF sensor is in the flow of the intake air. It is situated behind the air filter, which will clean the air to some degree, but there are still many thousands of litres of air that flows past this sensor. Over time, it will get dirty.
What happens when I Change my MAF sensor?
When you change a MAF sensor, you need to disconnect the battery for about 10 minutes so the computer forgets the learned parameters and resets to the factory parameters. Then it goes into learn mode and may take a little while before it learns all the parameters of the new MAF sensor.
What causes rough idle after replacing mass air flow sensor?
Replaced air filter and maf sensor. Problems with vehicle turning off seemed to go away but now I have a rough Idle. Car will drop below 1000 rpms and then rev back up to over 1500 like it wants to shut off. Idle problems seem to go away when maf sensor is disconnected. Car throwing codes p0171 and p0102.

How do you replace the mass air flow sensor?
Step 1 – When replacing a mass air flow sensor, first locate the sensor which is positioned in the air intake tube between the air filter housing and throttle body. Mass Air Flow Sensor. Step 2 – Release the safety clip and gently pull the connector from the sensor.
What are the symptoms of a bad mass air sensor?
The most common symptoms from a bad mass air flow sensor are slow accelerating and reduced engine power. You can also notice a difference in the fuel economy as the main function of the mass air flow sensor is to let the engine know how much fuel it should inject.
What are the symptoms of a bad Mas sensor?
Signs of a bad MAF sensor may mimic problems such as low vacuum, low compression, or low fuel pressure due to a bad fuel pump. The most common symptoms of a malfunctioning MAS sensor include: • The engine is hard to start or has trouble turning over. • The engine stalls soon after starting.
What is a bad mass air flow sensor?
An MAF , or Mass Air Flow, sensor is a device used to measure the density of air flowing into the engine. The MAF sensor can go bad for numerous reasons, resulting in symptoms a car operator can use to help determine and resolve the problem. A lit “Check Engine” light is an early symptom of an MAF sensor going bad.
