throttle<\/a><\/strong> response as well.<\/p>\n\n\n\nIn this comprehensive guide, we\u2019ll share all there is to know about the process.<\/p>\n\n\n\nReset the Throttle Position Sensor<\/h2>\n\n\n\n The computer keeps track of the throttle position, whether it\u2019s open or closed. Once the throttle body is replaced, the computer must be reprogrammed or reset, otherwise, it wouldn\u2019t know the accurate position of the throttle.<\/p>\n\n\n\n
This is why it\u2019s important to reset\/reprogram the throttle position sensor after resetting the throttle body. Follow these steps to reset the throttle position sensor:<\/p>\n\n\n\n
\nTake your vehicle out for a drive, and make sure you\u2019re driving over 40 mph of speed.<\/li>\n\n\n\n Come back to the garage and remove the fuse. Leave the vehicle as it is for 10 minutes.<\/li>\n\n\n\n Now, use an OBD2 scanner. These are essentials if you want to troubleshoot your car, and can save you a lot of time. So, if you don\u2019t have one already, we recommend getting one asap.<\/li>\n\n\n\n Once the OBD2 scanner is connected, start your car and push the accelerator. Don\u2019t remove the ignition key in this process. If your vehicle features a push-to-start button, hold it down.<\/li>\n\n\n\n Then, remove the negative cable of the battery. Keep it like that for 15-20 minutes.<\/li>\n\n\n\n As for the final step, reconnect the battery. Make sure the cable is tightly attached. This shall reset the throttle position sensor or TPS.<\/li>\n<\/ul>\n\n\n\nEven after you\u2019re done with this process, it\u2019s important to check out the OBD2 scanner. If you see the \u201cCheck Engine\u201d light still on, then there\u2019s something else wrong with your vehicle.<\/p>\n\n\n\n
In this case, you need to check out for other problems in your vehicle.<\/p>\n\n\n\n\nhttps:\/\/youtube.com\/watch?v=No8z2xO57Gs\n<\/div><\/figure>\n\n\n\n
Calibrate the New Throttle Position Sensor<\/h2>\n\n\n\n Resetting the TPS, or throttle position sensor, isn\u2019t enough. To ensure the sensor works perfectly, you need to calibrate it as well. Otherwise, the sensor will fail to recognize the position of the throttle accurately.<\/p>\n\n\n\n
Without proper calibration, the sensor will input the wrong fuel-to-air ratio to the cylinder. This will not only reduce the efficiency of the whole system but may lead to further problems down the line.<\/p>\n\n\n\n
To calibrate the throttle body, you need to follow these steps:<\/strong><\/p>\n\n\n\n\nStart by regulating the voltage of the sensor manually. How do you do that? Look for a black rubber-like attachment on the throttle body. You can shift it back and forth to get the desired amount of voltage flowing through the sensor.<\/li>\n\n\n\n Now, disconnect the TPS from the old throttle body and install it into the new one. If you want, you can get a new TPS from the market. We recommend sticking with the existing one unless it\u2019s broken or malfunctioning.<\/li>\n\n\n\n Take a multimeter, and connect its negative terminal to the battery. Set the multimeter to DC voltage.<\/li>\n\n\n\n Look for a red wire connecting the TPS and the throttle body. Connect this wire with the multimeter using the positive cable.<\/li>\n<\/ul>\n\n\n\nOnce you\u2019ve followed through on this, it\u2019s time to check the voltage. When you put it at close throttle, you\u2019re supposed to get 4.5-4.6 volts.<\/p>\n\n\n\n
As you keep applying the throttle, you should experience an upward shift in the voltage, but it shouldn\u2019t exceed 5 volts in most cases.<\/p>\n\n\n\n
If you see a lower or higher voltage on the multimeter than the suggested level, you should change the voltage output from the throttle body to adjust it.<\/p>\n\n\n\n
Verify Throttle Response<\/h2>\n\n\n\n Once you\u2019re done replacing and recalibrating the throttle sensor, it\u2019s necessary to verify if it\u2019s working as it should or not. To do so, take your vehicle for a drive and pay attention to how snappy the throttle response is.<\/p>\n\n\n\n
The throttle is supposed to respond as soon as you press the accelerator pedal. Bring variety in speed and driving style to check if the throttle is working perfectly under every condition or not.<\/p>\n\n\n\n
Also, check whether the RPM of the engine is shifting with the throttle or not.<\/p>\n\n\n\n
There shouldn\u2019t be any delay. If you\u2019re experiencing any delay, you need to recalibrate and reprogram the TPS. If that doesn\u2019t fix the issue, you probably have to get a new TPS.<\/p>\n\n\n\n
Additional Expert Tips You Should Follow<\/h2>\n\n\n\n The processes mentioned above are the steps that you must take after replacing a throttle body. However, there are some other procedures that you must follow. These are as follows:<\/p>\n\n\n\n
\nCheck for Loose Connections<\/strong><\/li>\n<\/ul>\n\n\n\nWhen the TPS and throttle body are finally installed, check every connection to make sure they\u2019re connected tightly.<\/p>\n\n\n\n
Also, look out for the quality of the connections. Loose or damaged cables can lead to long-term problems for your vehicle.<\/p>\n\n\n\n
\nLook Out for Vacuum Leaks<\/strong><\/li>\n<\/ul>\n\n\n\nSometimes, replacing the throttle body and TPS leaves vacuum leaks in the intake system. This mainly happens when certain hoses aren\u2019t connected back properly. In the worst-case scenario, there might be cracks or leaks in the intake manifold.<\/p>\n\n\n\n
So, look out for any sort of hissing noise or other signs of leaks. If you find any such leak, make sure to fix it before you start using the vehicle.<\/p>\n\n\n\n
