The Honda P code is displayed when the mass air flow sensor signal is lower than expected. This code can be caused by a faulty mass air flow sensor, a vacuum leak, or a malfunctioning engine control module. The mass air flow sensor measures how much air enters the engine. The engine computer PCM uses the mass air flow signal to determine how much fuel to inject. If the mass air flow sensor signals are lower than expected, the code P is set.

Advertiser Disclosure. With a P code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the MAF circuit. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P code. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P code. When it comes to making repairs associated with the Pcode, one or more of the below repairs may be needed to solve the underlying issue.

Today's cars can let you know there's an issue by illuminating a warning light and throwing up a fault code that you can explore using a fault-code reader. The MAF sensor measures the amount of air entering the engine and sends that information to the car's computer so it can make necessary adjustments to fuel delivery. If this sensor experiences a problem, it will cause a decrease in engine performance, poor fuel economy, or even stall completely at times. The most common symptom of a P code is a decrease in engine performance. Your car may feel sluggish or have difficulty accelerating. You might also experience an increase in fuel consumption as the car struggles to compensate for the MAF sensor issue. Usually, you'll see one or more warning lights lit up on your dashboard when this fault code is triggered. The most common cause of a P code is a faulty MAF sensor. This could be due to debris, contamination or an electrical issue. The wiring and connector of the MAF sensor may also need to be checked for any faults.

If the code returns, the MAF Sensor must be replaced. Check the snorkel for these signs. An exhaust back pressure test must be performed if it is suspected that a catalytic converter is clogged. For the hot film to maintain its temperature, the ECM must supply more electric current as air flow increases. Sort by Oldest first Oldest first Newest first Most reactions. It is necessary to compare the airflow sensor readings with the known good sensor or with the readings from another car of the same model using the scan tool at different RPMs. Footer Subscribe Newsletter. In fact, yes. The engine computer PCM uses the mass air flow signal to determine how much fuel to inject. Explore Our Forums. Maybe run a can of cat cleaner through as a start.

An exhaust back pressure test must be performed if it is suspected that a catalytic converter is clogged. Lack of power at higher RPMs is one of the symptoms of a clogged catalytic converter. I spent a few years in aviation manufacturing after 34 years in the Acura and Honda repair field. Don't use brake cleaner or other solvents. Check the wiring harness for obvious damage. I'd do that before loading the parts cannon. Good luck and please keep us informed. There are two reasons why this is important. You may very well have a clogged catalytic converter if you get P and a noticeable power loss at speed in your Civic. I didn't have my code reader and waited until I got home to check the codes but during the trip I could definitely feel a lack of power. Their first disadvantage is their high price. I worked as Honda service technician for a long time. The following sections will explain what this means and possible fixes. As a result, it is possible for the car to start and run at idle but bog down as soon as the engine is revved.
