What does the code vtm 4 mean on a honda pilot?
Variable Torque Management 4WD System
The Variable Torque Management 4WD System (VTM-4) automatically transfers varying amounts of engine torque to the rear wheels under lower traction conditions. Because of the amount of torque applied to the rear tires, they should not spin.
What happens if you have a misfire on your Honda Pilot?
The P0304 trouble code will trigger the Pilot’s service engine soon light. The vehicle itself may begin to run rough. It depends on how serious the misfire is. The vehicle may produce excess vibration, especially at lower RPM. Fuel mileage may suffer. You may smell raw gas coming from the tail pipe.
What does cylinder 4 on a Honda Pilot mean?
The engine is also not firing all of the fuel, so raw fuel is also passing through Cylinder 4 into the exhaust. Mileage may suffer as well when your Pilot has P0304 as well. P0304 is a cylinder specific misfire code, which means that Cylinder 4 is misfiring and causing the code.
How does a Honda car know its idle speed?
What you have is a computer that’s literally “chasing” a good idle speed. Techs call this a surge. Honda uses most of those same components to determine idle in their vehicle. However, they use a fast idle valve that has engine coolant running through it.
What causes the p0304 trouble code on a Honda Pilot?
There are quite a few things that can cause the P0304 trouble code to trigger the Honda Pilot. Here are the most common problems that will throw the code. They are presented somewhat in order from most to least likely to be causing the code: Bad Spark Plugs– Spark plugs are one of the most common causes of P0304.
What causes Honda Pilot to run rough at idle?
These packs are fired by the engines computer at exactly the right time to provide the optimal ignition timing. If a coil pack goes bad, it’ll cause a misfire and rough idle condition. Really, your Pilot will be running rougher at any RPM, but a misfire will be most pronounced at idle.
Why are the spark plugs on my Honda Pilot not working?
Spark Plugs – One of the absolute most common causes (if not the most common reason that your Pilot may be misfiring) is the spark plugs. Although most modern vehicles use iridium spark plugs, they still need to be changed at the manufacturers recommended interval.
What are the O2 sensors on a Honda Pilot?
The oxygen sensors that are equipped in your Honda Pilot are responsible for monitoring the exhaust to help the ECU determine the correct air/fuel mixture. Of all the sensors equipped in your vehicle, the O2 sensors may have it the hardest. They deal with super hot exhaust that can cover them in deposits that can leave them ineffective.
What causes an Audi A4 to idle rough?
A super lean running engine will often idle rough. The fuel injection systems job is to atomize the fuel into fine mist. If a fuel injector has an issue with this process, it will either let too much or too little fuel into the combustion chamber relative to the amount of air.
