What is the trouble code for the throttle 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.
What does p0122 mean on a TPS sensor?
A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.
Why is TPS signal voltage high and low?
I changed the MAF sensor, idle air control and finally the throttle position sensor a few weeks ago. None of this fixed the problem. However, this morning the CEL finally came on for about 10 seconds, then turned off. It stored codes 21 AND 22, meaning that TPS signal voltage was both high and low.
Can a dirty TPS sensor be a problem?
Sometimes, the said symptoms can be linked to a dirty TPS sensor. So yes, you can actually clean it instead of outright buying a replacement. This will save you a lot of money and time.
A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.
When does the throttle position sensor display a low voltage?
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. They are:
What happens if you have a bad TPS sensor?
Acceleration issues: A bad TPS may cause all sorts of power issues. 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.

Why is my throttle pedal in limp mode?
If playback doesn’t begin shortly, try restarting your device. An error occurred. Please try again later. (Playback ID: JXZuAnDFqMyoB1FW)
How does the throttle pedal position sensor work?
As the throttle blade moves, the TPS sends a signal to the PCM (Powertrain Control Module). Usually a three wire sensor: A 5 volt reference from the PCM to the TPS, a ground from the PCM to the TPS, and a signal return from the TPS to the PCM. The TPS sends the throttle position information back to the PCM on this signal wire.
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.
What should I do if my throttle position sensor fails?
If one of the sensors fails, the control module will likely put the vehicle in “limp mode” or “ reduced power mode ” as a fail-safe measure. You can test a throttle position sensor with a digital multimeter (DMM), a scan tool, or an oscilloscope. Using a DMM is the method most DIYers are comfortable with.

Why is my p0123 throttle position sensor not working?
Here are some of the reasons why the P0123 trouble code generates. • Throttle position sensor not positioned correctly. • Throttle position sensor short circuit. • Defective throttle position sensor. • A defective pedal position sensor. • Contaminated throttle body. • Poor or damaged wiring.
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.
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 happens when the throttle gets stuck in an open position?
When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle. What are signs of a bad Throttle Position Sensor? Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off.
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.
