We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. Look up the other , please use the search box. Look up your code definition. As pressure readings change, the sensor varies the voltage and the computer reads that to determine input.
In the case of a broken wire, the sensor never sees the voltage and the computer assumes a major fault. In such cases, other components like the catalyst can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction. The underlying cause might be fouled spark plugs, bad plug wires, a weak ignition coil, dirty injectors, a shorted or open injector, low fuel pressure, a vacuum leak, a leaky head gasket, burned exhaust valve or a camshaft with a bad lobe. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. If it is damaged, repairing it should solve the problem. Now don't ask yourself; What should you do with P0404 code? P0404 Acura Auto Trouble Code P0404 Acura Auto Trouble Code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.
Due to the amount of free content we provide, we cannot guarantee the accuracy of all information. You should also check that the spark plug gap is set properly. If there is a link to a specific diagnosis strategy for the code then follow that and start testing. When it fails to recirculate this gas it can raise the combustion chamber temperature. If this is the case, the engine may idle rough, or not at all. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. But, they are not very likely.
Detonation can lead to engine damage. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Misfires can be caused by ignition problems, fuel problems or compression problems. We do our best to update these Acura check engine light codes as frequently as possible. The list of automotive Makes at the right edge of the screen. The currently selected is for the Honda makes. P0404 Acura Possible Solution: Excessive air inflow can be caused by a vacuum leak, a dirty sensor or, an exhaust gas recirculation valve not closing properly.
These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Spark plugs typically need to be replaced every season or 25 hours of use. The information contained on this site is presented for informational purposes only. Now don't ask yourself; What should you do with P0404 code? Since exhaust gas is inert, it displaces oxygen and fuel, thereby lowering cylinder temps, which, in turn, lowers oxides of nitrogen emissions. If there is a good ground, then check the control circuit. If you have any doubt as to repairs on your vehicle, please contact your technician. If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator.
If it is, then the problem is likely intermittent. So you should chech it on our car models. These are listed in numerical order for easy searching. Please feel free to leave a comment below if there is anything that you would like to add that can improve this article. The problem is caused by the variable cylinder management system switching on and off during light throttle conditions, at cruising speeds, or when driving on flat roads. However, Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc.
Given the robust nature of today's emissions control components, it is entirely possible for an individual component to malfunction without leading to an immediate increase in emissions at the tailpipe. Since exhaust gas is inert, it displaces oxygen and fuel, thereby lowering cylinder temps, which, in turn, lowers oxides of nitrogen emissions. Please use the form on our Contact Page to get in touch with us. If you have any doubt as to repairs on your vehicle, please contact your technician. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. We do ask that you please read the info available on the site first so that we can help reduce repeat questions.
Since exhaust gas is inert, it displaces oxygen and fuel, thereby lowering cylinder temps, which, in turn, lowers oxides of nitrogen emissions. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. Below you will find the most complete list of Acura trouble codes available. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. We are not responsible for any actions you take on your vehicle.
