Also, jerking can be caused by bad spark plugs or coil packs. It’s bad for your motor mounts when this happens.

Jerking– As you go down the road, you’ll feel your Civic really jerk and hesitate as the engine speed changes erratically.And when it does, it doesn’t usually run very well. Hard to Start– Without knowing the proper amount of air entering into the intake, it can be really difficult for the engine to start.The exhaust color usually doesn’t change. A lean condition is when there is too much air relative to fuel in the air fuel mixture. The exhaust color is usually darker when running rich. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. Idle Issues– Your Civic may run rich or lean when idling, or it may also idle erratically.Here are the most common symptoms of a bad or failing MAF sensor: When the mass airflow sensor has gone bad, you’ll definitely feel it. And, most of the time they are right by the air box and easy to replace.įaulty Mass Airflow Sensor Symptoms: Honda Civic If you do determine that you need a new mass airflow sensor, they aren’t too expensive. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. It passes this information onto your Civic’s ECU. A bad mass airflow sensor can leave your Honda Civic’s engine running rough, or even inoperable.Ī MAF sensor measures the density of the air entering the intake manifold.

For maximum performance use CRC Throt-L-Body and CRC Mass Air Flow Sensor Cleaner every time the air filter is serviced.The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. Located between the air filter and the throttle body, the MAF sensor can easily be cleaned with just a few sprays of CRC Mass Air Flow Sensor Cleaner – it only takes a few minutes. A contaminated sensor is likely to cause poor fuel economy, excessive emission, power loss, hard starting, stalling and even gear problems. Engines rely heavily on accurate readings from the MAF sensor to run smoothly and efficiently. CRC 5.56 Marine Multi Purpose LubricantsĬRC Mass Air Flow Sensor Cleaner is a safe and effective way to clean delicate Mass Air Flow (MAF) sensors in modern vehicles.
