Symptoms of a bad or faulty ignition trigger

If your car is hard to start, won't start at all, or the Check Engine light comes on, you may need to replace the ignition trigger.

The ignition trigger is an electronic mechanism in a vehicle's engine management system commonly found in some form or another on a wide variety of road cars and trucks. Most ignition triggers work like a magnetic sensor that "fires" when the device is rotated. When the mechanism fires, a signal is sent to the computer or ignition module so that the ignition system can be properly timed and fired. Most ignition triggers are in the form of a magnetic Hall effect sensor combined with a magnetic wheel. The components are usually located inside the distributor, under the ignition rotor, or next to the crankshaft pulley, sometimes with the brake wheel being part of the harmonic balancer. The ignition trigger serves the same purpose as the crank position sensor, which is also common on many road vehicles. Both provide a vital signal on which the correct operation of the entire engine management system depends. When a trigger fails or has problems, it can cause serious handling problems, sometimes even to the point of incapacitating the vehicle. Usually, a faulty ignition trigger will cause several symptoms that may alert the driver to the problem.

1. The car does not start well

One of the first symptoms of a faulty ignition trigger is a problem starting the engine. If there is any problem with the ignition trigger or the brake wheel, it may cause the signal transmission to the computer to fail. An incorrect trigger signal to the computer will cause the entire engine control system to shut down, which can lead to engine starting problems. The engine may require more starts than usual to start, or it may take several turns of the key before it starts.

2. Check Engine light comes on.

Another sign of a possible problem with the ignition trigger is an illuminated check engine light. Some systems will be equipped with redundant sensors that will allow the engine to run even if there is a problem with the ignition trigger. In addition to performance issues, any ignition problems can be detected by the engine's computer, which will illuminate the check engine light to notify the driver of the problem.

3. Car won't start

A no start condition is another sign of a possible problem with the ignition switch. Some engine management systems use the ignition trigger as the main signal for the entire engine management system. If the trigger does not work or there is a problem, this signal may be compromised or disabled, which may result in an inability to start due to the lack of a basic signal for the computer. The no start condition can also be caused by problems with the ignition and fuel system, so it's a good idea to run a proper diagnosis to be sure of the problem.

Ignition triggers, in one form or another, are found on most vehicles and are an essential component to the proper operation and handling of a vehicle. If you suspect that your vehicle may have a problem with the ignition trigger, have the vehicle checked by a professional technician such as AvtoTachki to determine if the trigger should be replaced.
