What makes knowing the position of the throttle so important that it needs a sensor? This question usually pops up when you look at the small sensor attached to the throttle body. And with that statement, you have unconsciously doubted the function of one of the important parts in your car. The throttle position sensor determines the position of the throttle valve every time the engine operates. The signals given out by the sensor are high-frequency and can actually cause different - and sometimes dangerous - reactions from the other parts. Thus, proper installation of the sensor is vital for the survivability of your vehicle. To make sure that the sensor is properly installed, here are the basic -INGs to guide you:
Open the hood of your vehicle. On most car models, the throttle position sensor is located at the air intake hose which is near the engine. The sensor is mostly plastic so it is easy to differentiate it from the rest of the assembly.
The sensor is usually put in place by four bolts. You can easily remove the bolts using a screwdriver or a ratchet and socket. Next, you need to remove the wire connected to the sensor. To do this, simply press the lock on the side and pull the connection out. You should now be able to take the entire sensor out of the throttle body.
Before connecting the new sensor, check if the new part matches the old sensor's harness connection and side structure. If it matches, place the new sensor where the old one was. Make sure that it fits the throttle body well. Incorrect installation greatly harms the performance of your car. Place all the bolts back in place.
Connect the male harness to the female port. You should hear a click and lock sound. A test drive would help check if the installation is done properly. Observe carefully the way the transmission shifts at low RPMs.
Known as the vehicle's brain, the engine control unit (ECU) controls ignition timing, fuel delivery, transmission shifting, cruise control, engine torque reduction, and charging output of the alternator. However, the ECU wouldn't be as effective at all these tasks if the throttle position sensor is down. Positioned on the butterfly spindle, the throttle position sensor is tasked to monitor the throttle position, measuring the engine's load, acceleration, deceleration, idle or wide open. The ECU controls the ignition timing and fuel injection timing depending on the throttle's position as well as on the rate of change of such position. Eventually, your factory throttle position sensor will wear out and therefore lose its ability to send proper signals to the ECU. So when this happens, get a replacement right away.
