Can throttle position sensor affect transmission shifting?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
Will a throttle position sensor throw a code?
a faulty tps can set a trouble code in the computer if the voltage value is either not present, sporadic, slow or constant, and this can illuminate your check engine light.
What does a faulty throttle position sensor cause?
What happens when my throttle position sensor goes bad. When a TPS goes bad, then the car's throttle body won't function properly. It could either stay shut or it won't close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won't start.

How many hours does it take to replace a throttle body?
How long does a throttle body replacement take? The job usually takes around an hour for either a replacement or a cleaning.
Can a throttle position sensor cause a no start?
No Start Condition Quite rarely but surely enough a bad throttle position sensor can create a no-start condition where you may be able to just crank the engine and not turn it over.
What is a throttle position sensor?
A throttle position sensor or TPS sensor is merely a small black plastic sensor attached to the throttle body that calculates the position of the throttle as it opens a butterfly valve to regulate the air intake from the input of the driver.
Where is the throttle position sensor located?
We put together a helpful guide on how to locate the TPS sensor on most engines.
Symptoms of a bad TPS (throttle position sensor)
We have outlined 5 symptoms to check out to determine if your TPS sensor needs attention. While these are good indicators there may be other symptoms not listed that could still be a faulty TPS sensor. The only way to know for sure is to check the electrical resistance of your TPS sensor is operating correctly.
How do I test my TPS sensor?
The process of testing your TPS sensor is not hard but does require attention to detail as you can damage your wires or your Multi-Meter if not done properly. Also, this method only works on mechanical throttle bodies.
Throttle Position Sensor Replacement Cost – Chart
Taking the average of all the parts listed below from suppliers that had TPS sensors available for the models listed we found that the average cost of TPS sensors is $52.50 in 2021. This makes replacing this part relatively inexpensive. The tools needed to diagnose and replace on average should not exceed $110.
How to Replace a TPS sensor?
Step 1. Disconnect – Remove the negative terminal on your battery before you begin disconnecting your TPS sensor. This prevents any damage to new parts as you reconnect them or unintentional shocks to you.
Engine Load Detection
The throttle position sensor signal, as well as the intake volume signal measured by the airflow meter and the absolute pressure sensor signal of the intake manifold, are the main parameters used by ECM to calculate the engine load. And they can monitor each other for signal consistency to see if any sensor is faulty.
Fuel Injection Quantity Control
ECM calculates the engine load according to the throttle position sensor signal, based on which, the fuel injection quantity is corrected and controlled. When starting the engine, the fuel system supplies a thick mixture to the engine to ensure the smooth starting of the vehicle.
Ignition Timing Control
The throttle position sensor signal directly reflects the load of the engine, and the ignition timing will be adjusted due to the change of the engine load. Therefore, a TPS is one of the main sensors for ECM ignition timing control.
Idle Speed Setting
ECM determines whether the engine is in idle condition according to the throttle position sensor opening angle signal (%). If the signal shows that it is idle, the ECM maintains the set idle speed through an idle air control and ignition control.
Air Conditioner Control
Throttle position sensor signals are also used for traction control and air conditioner compressor control. If the ECM detects that the throttle position is in or towards the fully open position, the air conditioner compressor will be withdrawn to meet the vehicle's traction requirements.
AT Shift Time Control
The throttle position sensor signal and speed signal are the two most important parameters to determine the automatic transmission up and down gear. If the throttle opening angle is very large, it indicates that the driving force of the vehicle needs to increase, the power control module (PCM) or automatic transmission control module (TCM) will reduce or delay the shift.
AT Lock Clutch Control
Throttle position sensor signals are used for engine control.
How to remove throttle position sensor?
Part 1 of 2: Removing the throttle position sensor. Step 1: Locate the sensor. The throttle position sensor is mounted to the throttle body on top of the engine. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.
What is a TPS sensor?
The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc. Basically, the throttle position sensor is a variable resistor. Its internal resistance and output signal voltage change in relation to throttle position. Some common symptoms of a failed throttle position sensor include hesitation, poor acceleration, rough idle, increased emissions and an illuminated Check Engine Light.
Where should the throttle sensor be mounted?
It should be mounted to your throttle body, which is on top of your engine. You should disconnect your negative battery cable before removing the sensor. This helps you avoid the risk of electrical shock or causing an error code on your engine control module.
What is the function of the throttle position sensor?
When you press down on the gas pedal, your throttle body unit's valve opens. This causes your throttle position sensor to adjust the engine intake manifold accordingly .
Why is my throttle position sensor not working?
Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you’ll need professional software to reprogram your sensor. This job is best done by a professional mechanic. If your sensor just needs repairs, it could be the result of faulty or loose wiring.
How to install a new sensor?
Install your new sensor by working backward through the removal steps. Start by installing the sensor using the mounting screws. Next, connect your sensor to your vehicle's electrical system using a convenient electrical connector. You should be able to easily push it together and hear a distinct click. Check to ensure a firm connection.
Can you replace a sensor?
Completely replacing your sensor may be the best way to avoid future issues, but some issues can be easily fixed by reprogramming or repairing your sensor. Reprogramming or resetting your sensor can sometimes solve these issues. This step can also be necessary when you install a new sensor.
Is throttle position sensor a corrosion sensor?
Just like any other electrical wiring, your throttle position sensor is susceptible to corrosion and faulty connections. Once you’ve established the issue is with your sensor and that it isn’t a programming fault, check the wiring and connection points before purchasing a new one.
