The P0720 code indicates a problem with the output speed sensor, which doesn’t function properly for a few reasons. These reasons may include the sensor itself and things like old transmission fluid, ...

Learn how to diagnose active wheel speed sensors, avoid ABS misdiagnosis, and prevent costly comebacks in your shop.

If the throttle-position sensor fails, the engine can also run using just the engine speed and MAP sensor info as a failsafe. The system is always sequential fire, no matter the rpm.

All electronic engine-management systems use a throttle position sensor to monitor the percentage of throttle opening. Connected to the throttle shaft, it tells the computer whether the car is ...

All but the speed sensor can be sourced from the donor vehicle. The fuel-injection system needs to know vehicle speed, but we imagine you also want to maintain the mechanical speedometer.

Engine speed measurement is instead already performed in modern engine control systems and therefore being capable of obtaining MFB50 related information from this signal means obtaining it at ...

When talking about modified cars, one term that gets thrown around a lot is ECU tuning. If done right, it can be really beneficial to your car's performance.

SAE Transactions, Vol. 111, Section 3: JOURNAL OF ENGINES (2002), pp. 961-968 (8 pages) The paper presents the development of a methodology for the evaluation of the Wide-Open-Throttle (WOT) torque ...

The FADEC monitors sensors and based on the inputs received through other systems, it can adjust things like fuel flow and engine speed automatically; sometimes even overriding the pilot controls.
