Knock sensors are devices used in internal combustion engines to detect engine knock or detonation. The knock sensor detects vibrations and sends a signal to the engine control module (ECM), to ...

The ignition control module plays a pivotal role in the ignition system by controlling the ignition timing and generating sparks at the right moment. It receives signals from various sensors, such as ...

In module 2 you will learn how sensor software is adjusted for optimal performance in the field. First, you will review how non-linear sensor response curves are linearized for more predictable ...

If the brake pedal moves rearwards while accelerating, it may result in an inaccurate Learned Release Position in the Engine Control Module (ECM), with the ECM Brake Pedal Position sensor showing ...

These sensors work in tandem to send the powertrain control module (i.e., the computer that manages the engine and transmission) the speed difference between the engine crankshaft and the ...

The powertrain control module isn't the only computer that you can find on contemporary cars, but it is the primary computer that controls most systems and functions for vehicles that utilize a PCM.

According to NHTSA, the recall covers 552,188 of the pickups due to a loss of signal between the transmission output shaft speed sensor and the powertrain control module causing the truck to ...
