Ignition Trigger Replacement Service

What is the Ignition Trigger all about?

In order for your engine to crank, it needs fuel and electricity. The fuel is supplied by the fuel pump, and the electricity is provided by the ignition coil. There’s one more thing – the right location. The car’s computer needs to know the position of the crankshaft in order to start the car. This is provided by the ignition trigger. There are many different types of ignition triggers used on the market today, including:

  • Trigger wheels
  • Crankshaft sensors
  • Camshaft sensors

Regardless of the type of sensor, they do the same thing, which is to send position information to the ECU, so that the car’s computer can operate the ignition system and crank the engine. The sensor sends a reference signal to the computer, which then determines the appropriate timing for ignition.

Keep in mind:

  • The ignition trigger system is not inspected as a part of regular maintenance and only checked if there is a suspected problem.

How it's done:

  • The trigger wheel is installed
  • The defective ignition trigger sensor is removed
  • The new sensor is mounted and new ignition trigger sensor tightened
  • The trigger wheel removed and crank bolt is tightened
  • The engine is started and timing is checked for proper ignition

Our recommendation:

We recommend having any ignition problem inspected and diagnosed by our expert mechanics as soon as possible. Because the ignition trigger sensor is responsible for first determining crankshaft position, it is possible that erroneous information could cause damage to the engine.

What common symptoms indicate you may need to replace the Ignition Trigger?

  • Car will not start or will only start intermittently
  • Engine experiences hard starts
  • Check Engine light is on

How important is this service?

Without an operational ignition trigger system, your car’s computer has no way to determine the correct ignition position, and may not start at all. This can be a constant or intermittent problem. Have the issue diagnosed by our experienced mechanics as soon as possible to prevent any future damage.
