How to repair a throttle position sensor on a pigtail?
Crimp the butt connectors onto the pigtail with the crimping tool or pliers. Gently tug the wires to ensure they are crimped into the butt connectors. Wrap the butt connectors, including 1 inch of wire on each side of the butt connectors, with electrical tape. Plug the code scanner into the data link port on your vehicle.
What should the throttle position sensor be at idle?
At the idle position, the reading should be 0.45 volts. Before you think of replacing the throttle/pedal position sensor, it is a good idea to first have the sensor cleaned and serviced as a dirty sensor transmits incorrect data to the PCM.
How do you clean a throttle position sensor?
Clean the sensor using a cleaning solution but ensure that you do not clean the actual sensor with anything liquid. Clean thoroughly around the sensor until all dirt is removed. Once the sensor is cleaned, use a dry cloth and gently rub to remove any liquid residue. Then connect the sensor back in its place, close the hood and you are good to go.
How many wires on the throttle position sensor?
The TPS sensor is a potentiometer, a variable resistance that decreases in proportion to the throttle plate position. So the more open the throttle is, the less resistance is applied in the potentiometer. The TPS sensor is usually a 3 wire configuration.
What does the throttle angle sensor do?
The purpose of a throttle position sensor is to keep your car working by controlling the throttle. With the passage of time, the sensor loses its efficiency and thus has to be replaced.
What does the idle position sensor do?
An idle air control valve, also called an idle air sensor control motor, is an electrically operated valve that controls the amount of air that bypasses the throttle plate in cars with a fuel injection system [source: Autozone ]. This causes the idling speed of the engine to change as needed.
What is a throttle control sensor?
A throttle position sensor is a device that can detect a difference in throttle position. The Engine Control Unit (ECU) uses throttle position sensors in internal combustion engines to gauge the throttle’s position as well as the rate of change in the throttle’s position in order to relay this information to other devices in the engine.
