The fuel injection system is responsible for adding fuel to the engine cylinders. The amount of fuel and the timing of the fuel injections are vitally important for successful combustion of the air and fuel mixture to take place. Then your engine can generate enough power to satisfy your acceleration demands. The powertrain control module

When you have an idle engine, the RPM must be managed to accommodate the other loads put on the engine. Some of the most common loads include the windshield wipers, heater, air conditioner, integrated GPS system, and radio. The more devices and systems that are activated, the more stress the idle engine is put under.

Engine knocking can be a very serious problem if it occurs. As you may know, the engine cylinders require the proper air to fuel ratio in order for successful combustion to take place. But when the air to fuel ratio is not correct, the mixture won’t burn evenly. It will ignite uneven pockets of fuel

There are a whole series of components in a vehicle which allow acceleration to take place. The accelerator pedal assembly has a pedal position sensor and the intake manifold has a throttle position sensor on its throttle body. Whenever you step on the gas pedal to accelerate the vehicle, you are basically demanding more power

People love to listen to music in their cars. You must have a high-quality sound control system if you want the music to sound smooth and crisp. A lousy sound control system would destroy the harmonics of the music and songs. Most people purchase sound control systems for their living rooms, but they forget their

Trouble Code P1345 means something a little bit different for each type of car because of the manufacturers. The big differences are really in how the code is described by each manufacturer. Generally, trouble code P1345 refers to a problem with the ignition system of the vehicle. But in a GMC or Chevrolet, P1345 means

Every vehicle has a crankshaft position sensor which monitors the crankshaft’s position and sends information about the position to the engine control module. As part of the ignition system, the crankshaft and the engine control unit work together to manage the spark timing. The crankshaft position also works in harmony with the camshaft position sensor

A diagnostic trouble code (DTC) is a code which identifies a specific problem with an automobile. If your automobile is not functioning properly and you don’t know why, then an auto technician will run a diagnostic check on the engine control unit to figure out the problem. The engine control unit is the central computer

The exhaust manifold of a vehicle contains oxygen sensors which track the amount of unburned oxygen coming out of the engine after the internal combustion process takes place. As you know, exhaust gases are produced when air and fuel are ignited after they’re combined. The engine control unit wants to track the amount of unburned

An automatic transmission allows the gear ratios of a vehicle to change automatically as you are driving. This means you don’t have to shift gears with a gear stick as you do in a manual transmission vehicle. Just step on the gas pedal to accelerate faster, and the torque demand will be met by the
