However, they may not work for other vehicles that are displaying the P0122 code. Code P0122 gets logged when the throttle position sensor “A” displays lower voltage than normal. Several OBD-II trouble codes also cover the performance of the throttle position sensor at the “A” position.
Can a bad throttle position sensor cause spontaneous acceleration?
Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn’t step on the gas. Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow.
Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
What kind of sensor is the throttle position sensor?
Throttle Position Sensor. This type of sensor is known as a potentiometer. A variable resister used to control voltage in a circuit. The TP sensor is used to detect engine load. Its output is shared by the PCM and the TCM. This sensor’s input signal along with the vehicle speed sensor are used by the TCM to provide optimal shift timing.
How is a TP sensor used in an automatic transmission?
The PCM and the TCM share the output. This sensor’s signal, along with the vehicle speed sensor, is used by the TCM to provide optimal shift timing. Most TP sensors have extra pins for extra internal functionality. For this discussion, we look at three terminals and the sensor’s connection to the automatic transmission.
What does code p0122 on a TPS mean?
Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input What Does Code P0122 Mean? Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.

Why do I have a trouble code on my throttle?
Most often the cause of this code is either the TPS (Throttle Position Sensor) which is an integral part of the throttle body or the TPPS (Throttle Pedal Position Sensor) which is part of the throttle pedal assembly at your feet.
What is the error code for throttle position sensor?
If the module detects that the sensor is operating outside of a predetermined range, error code P0121 will be set. A throttle position sensor operating outside of a predetermined range can trigger code P0121.
What does the p0121 code on the throttle sensor mean?
The error code P0121 may indicate an issue related to your engine’s throttle position sensor. Like other throttle position sensor-related codes, this could lead to serious problems and can result in your vehicle not starting at all. Let’s take a look at code P0121 and its other potential consequences. What Does the P0121 Code Mean?
Why does the PCM need to learn the throttle plate?
It should be noted though that on almost all applications the PCM needs to learn the signal voltage that relates to the throttle plate being in the closed position in order to be able to compensate for wear in the sensor, and the throttle plate spindle bushings.
How is the TPS signal used in the engine?
The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes. The collected data determines precisely how much fuel to inject into the engine at any given moment.
Is the accelerator pedal a cable or sensor?
HINT: This electrical throttle system does not use a throttle cable. This accelerator pedal position sensor is a non–contact type. The accelerator pedal position sensor is mounted on the accelerator pedal to detect how much it is de- pressed.
What does the p0123 code on the throttle position sensor mean?
What Does the P0123 Code Mean? The P0123 code indicates a problem with the throttle/pedal position sensor. When the engine control module (ECM) detects that the throttle position sensor’s output voltage rating is exceeding the manufacturer specification, it generates the P0123 trouble code.
How is the idle position of the throttle valve determined?
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.
How can you tell if throttle position sensor is bad?
Below are several key signs of a bad throttle position sensor. One of the telltale signs of throttle position sensor problems is slightly delayed acceleration. If you notice a delay between the time you press on the gas pedal and the time the vehicle actually accelerates, take the car directly to a mechanic.
What happens when the throttle position sensor is bad?
A bad throttle position sensor may cause the car to unexpectedly buck or jerk around. It may also cause random surging of the engine when the car is idling.
How do I adjust the throttle position sensor?
While most throttle position sensors do not require adjustment, there are a few that do. Typically, adjustment involves connecting a voltmeter with back probe leads to the sensor signal wire and ground. Then, with the engine running, loosen the sensor screws. Rotate the sensor until the desired reading is achieved.
Can I change throttle position sensor?
How to disassemble and replace the throttle position sensor #Step 1: Disengage the throttle position sensor harness from the throttle body, located at the bottom of it. #Step2: Take out the throttle position sensor from the throttle chamber #Step 3: Use an anti-slip solution to enable easy removal from the throttle chamber, or when needed to replace it.
What is the p2119 code for the throttle?
P2119 – Throttle Closed Position Performance – this code sets when the voltage returned by the TAPS sensor does not match the closed throttle position stored in PCM memory. P2176 – Minimum Throttle Position Not Learned – this code sets if the memory is cleared and the throttle blade is not allowed to return to the fully closed position.
When does p1516 set the throttle position?
In these instances, P1516 will set when the voltage being returned by the sensor does not match what is being received by the actual throttle position sensor or in some cases, it may be a calculated throttle position. This particular code can set if the voltage changes from normal to 0 volts or 5 volts for a very short period of time.
How does the throttle position sensor work on a Durango?
By monitoring the voltage on the signal line, the PCM calculates throttle position. As the throttle va… The code that flashes is P0121 it is a 2000 Durango engine 4. 7 and I believe it has had a tune up but I made an appointment for wednesday to have it weatherized because we live in MN and its freezing here!!
What is a code p2135 throttle/pedal position sensor?
P2135 is a diagnostic trouble code (DTC) for “Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Where is the throttle pedal position sensor located?
A throttle position sensor (TPS) is a sensor used to monitor the air intake of a engine. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle.
