The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
What does code po122 mean?
A P0122 code is the generic OBD-II code defined as “Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input.” This code relates to the vehicle’s Engine Control Module (ECM) and TPS Sensor Circuit A output voltage and is triggered when the voltage falls below the sensor’s anticipated range.
Plugging in, repairing, or replacing wiring or circuitry that is associated with the throttle position sensor.
Repairing or replacing the throttle body.

What causes a P0222 code?
What Are Some Causes of a P0222 Code? Issues with the throttle or pedal position sensor or switch are common causes of this code. Wiring and connections may also be faulty, whether corroded or simply not providing an effective connection.
What causes throttle position sensor failure?
The TPS is essentially a potentiometer in a plastic case and it fails due to poor contact of the wiper. This can cause erratic readings or no readings. It is possible that the vehicle may not accelerate and then suddenly accelerate, indicating erratic contact.
How do you reset a Toyota throttle position sensor?
How do you reset the throttle position sensor on a Chevy?
Where is the throttle pedal position sensor A located?
A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.
Where is the throttle control sensor located?
A throttle position sensor is a type of sensor that monitors the air intake of a vehicle’s engine. It’s usually mounted on the butterfly spindle (also known as butterfly shaft) of the throttle body. From there, the sensor can directly and accurately monitor the position of the throttle.
Can you replace a throttle position sensor yourself?
Remove the throttle position sensor. Clean the sensor connector as needed using electrical contact cleaner or spray. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.
What happens when the throttle sensor goes out?
Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.
What are the symptoms of a faulty throttle position sensor?
Symptoms of a Faulty Throttle Position Sensor
An unexplainable bucking and jerking in the vehicle.
Sudden idle surges.
Sudden engine stalling without any apparent reason.
Hesitation while accelerating.
Sudden surges in speed while driving on the highway.
Intermittently flashing of check engine light for no apparent reason.
Can you drive with a faulty throttle position sensor?
Can You Drive With A Bad Throttle Position Sensor? Technically you can still drive with a bad throttle position sensor. However, do note that a bad throttle position sensor can cause inability to shift up, rough or slow idle and lack of power when accelerating.
Does throttle position sensor affect idle?
Uneven Idle
If your car can’t maintain a constant engine speed when it’s sitting still, your TPS may be on its way out. A constant level of fuel delivery is necessary to maintain a steady idle.
How much does it cost to replace a throttle position sensor?
Luckily, the TPS sensor is in a rather convenient location to change on most vehicles, right on the side of the throttle body. The throttle position sensor cost ranges from around $40 and up, depending on your car. Find the right fit for your needs at AutoZone.
How often should you change your throttle position sensor?
Recommended Services. The throttle position sensor (TPS) is only replaced if it tests bad. So there is no fixed replacement interval or “lifetime” for that part. They do occasionally fail though, in which case the Check Engine Light will illuminate with specific TPS codes.
What happens if you drive in a faulty throttle body for a while?
You might be wondering—is it safe to drive with a bad throttle body? The quick answer is no. Once it starts to show signs of going bad or being clogged, you should address the problem right away. Otherwise the vehicle may stall or fail to accelerate, creating a safety hazard.
What happens if you don’t fix a throttle body?
If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed. This will inevitably contribute to poor engine performance and, if it gets to that point, it should cause your check engine light to come on.
