what is a distributor pick up

by Catherine Block Published 3 years ago Updated 2 years ago

The function of a distributor pick-up is to provide a timing reference signal to the Ignition Control Module (ICM) or Engine Control Module (ECM) to indicate the mechanical dwell period for each ignition event. The mechanism requires a rotating reluctor and a stationary pick-up coil with a magnetised core.

How does a distributor pick-up work?

The function of a distributor pick-up is to provide a timing reference signal to the Ignition Control Module (ICM) or Engine Control Module (ECM) to indicate the mechanical dwell period for each ignition event. The mechanism requires a rotating reluctor and a stationary pick-up coil with a magnetised core.

What is the purpose of the pickup coil on a distributor?

They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation of the distributor and triggers the ignition system at the optimal moment to produce the best timed spark for best engine performance.

How do you test a distributor pick-up?

The purpose of this test is to check a distributor pick-up’s Hall effect signal during engine cranking or running conditions. View connection guidance notes. Use manufacturer’s data to identify the distributor pick-up circuit. Connect PicoScope Channel A to the distributor pick-up signal circuit. Minimize the help page.

When to replace the ignition pickup on an electronic distributor?

If your car has an electronic distributor ignition system and the engine stalls or car does not start, you may have to replace the ignition pickup. Electronic ignition pickups are a component found on traditional electronic distributor ignition systems.

How do distributors work?

As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly. Instantaneously, when the points open (separate) current flow stops through the primary windings of the ignition coil. This causes the magnetic field to collapse around the coil.

Distributors can sell to the final consumer or other businesses, while suppliers almost always sell to other businesses that will eventually sell to the final consumer. Distributors and suppliers may also both provide physical products to a company.

Further guidance

The function of a distributor pick-up is to provide a timing reference signal to the Ignition Control Module (ICM) or Engine Control Module (ECM) to indicate the primary circuit dwell period for each ignition event.
