What Does ABS Mean on a Car?
What does ABS mean on a car? An anti-lock brake system helps to bring a vehicle to a full stop safely in an emergency braking situation.
What does a Throttle Position Sensor do for your vehicle?
The throttle position sensor moves with the throttle and sends a voltage signal to the computer indicating throttle angle and speed of movement data. The computer uses this data to … Continue Reading What does a Throttle Position Sensor do for your vehicle?
What does a Yaw Rate Sensor do for your vehicle?
A yaw rate sensor (or rotational speed sensor) measures a vehicle’s angular velocity about its vertical axis in degrees or radians per second in order to determine the orientation of … Continue Reading What does a Yaw Rate Sensor do for your vehicle?
What does a MAP Sensor do for your vehicle?
There are a myriad of sensors underneath your hood that quietly do their jobs day in and day out without making a fuss. They may not be as visible as … Continue Reading What does a MAP Sensor do for your vehicle?
What does an EGR Position Sensor do for your engine?
The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage. Where … Continue Reading What does an EGR Position Sensor do for your engine?
What does a Camshaft Synchronizer Assembly do for your engine?
The camshaft synchronizer assembly consists of a camshaft position sensor mounted on an oil pump intermediate shaft. The synchronizer is driven off the camshaft, and sends the camshaft rotational position … Continue Reading What does a Camshaft Synchronizer Assembly do for your engine?
What does an Accelerator Pedal Sensor do for your vehicle?
The accelerator pedal sensor (APS) indicates the position of the accelerator on vehicle models with electronic throttle control. The APS is basically a throttle position sensor (TPS) with a pedal … Continue Reading What does an Accelerator Pedal Sensor do for your vehicle?
Velocity Check: What does a Vehicle Speed Sensor do?
The vehicle speed sensor or VSS measures transmission/transaxle output or wheel speed. The engine control module (ECM) uses this information to modify engine functions such as ignition timing, air/fuel ratio, … Continue Reading Velocity Check: What does a Vehicle Speed Sensor do?
Combustion Control: What does a Knock Sensor do?
The knock sensor creates a voltage signal based on the vibrations caused by engine detonation. The computer uses this signal to retard timing when spark knock occurs. Where are these … Continue Reading Combustion Control: What does a Knock Sensor do?
What does an Air Charge / Manifold Temperature Sensor do?
