How does the accelerator pedal position sensor work?
Accelerator Pedal Position Sensor. This is a component of the Drive-By-Wire system, which does away with the throttle cable. In a DBW system, the ECM receives an input from the APP sensor and then commands the appropriate throttle opening using a throttle actuator motor. See how this device works with this video.
What are the symptoms of a bad throttle / accelerator pedal?
Symptoms of a Bad or Failing Throttle/Accelerator Pedal Position Sensor. $79.99 – $89.99. Average rating from 4,829 customers who received a Check Engine Light is on Inspection. The days of having to constantly adjust the throttle cable due to a loose nut on the carburetor are long gone.
What does the TPS indicate when the accelerator pedal is free?
During movement of a vehicle, the signal delivered to the TPS is in the range of 3.5–4.7 volts; a value range that indicates that the throttle valve is in the open position. A closed-throttle position switch informs the PCM unit that the accelerator pedal is free, which indicates that the driver has removed his/her foot from the pedal device.
Is the throttle position sensor the same as the app sensor?
Throttle Position Sensor (TPS) The electrical circuitry to both the APP and TPS sensors is the same. Just like the APP sensor, the TPS sensor unit is mounted on the throttle body and converts the throttle body butterfly valve angle position into a voltage signal, which is transferred to the PCM unit.
Where does the accelerator pedal position information go?
The accelerator position information is transferred to the throttle actuator control (TAC) module and the powertrain control module (PCM). The accelerator position sensor is made up of two individual sensors, with both sensors designed to have individual sensor return wiring. Each sensor has a varying voltage range.
Is there a TPS sensor on the accelerator pedal?
The result is a smooth and responsive drive. Some cars use both an accelerator pedal position sensor on the pedal and one TPS sensor on the throttle body, while some cars only have a TPS sensor on the throttle body. A TPS sensor’s importance can be emphasized as it can affect the gas mileage and engine response.
How does the throttle position sensor work on a car?
This vital sensor allows your engine to maintain a proper amount of air. This feature is dependent on the throttle valve. 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.
Symptoms of a Bad or Failing Throttle/Accelerator Pedal Position Sensor. $79.99 – $89.99. Average rating from 4,829 customers who received a Check Engine Light is on Inspection. The days of having to constantly adjust the throttle cable due to a loose nut on the carburetor are long gone.
The accelerator pedal position sensor works by using a Hall Effect sensor that determines the location of the pedal by a magnetic field. It produces a change in the charge based on a change in the position of the pedal. The information is relayed to the ECM to let it know how hard you are pushing on the gas pedal.
How long do you hold the accelerator pedal to the floor?
Step 4: Press the accelerator pedal all the way to the floor and hold for 30 seconds. Step 5: Release the accelerator pedal and count for 25 seconds. Step 6: Press the Accelerator pedal to the floor and hold for 20 seconds.
What’s the throttle relearn procedure for a new battery?
Step 2: Press the accelerator pedal ALL THE WAY to the floor and hold it for 40 seconds. Step 3: Release the accelerator pedal ALL THE WAY and count for 35 seconds. Step 4: Press the accelerator pedal all the way to the floor and hold for 30 seconds. Step 5: Release the accelerator pedal and count for 25 seconds.
Why does my ECM not know when to press the pedal?
Since you use the sensor every day, these problems can eventually build up, or they can happen all at once. If the sensor fails, the ECM will not have the correct information about how much you are pressing on the pedal.
How to change the accelerator pedal release position?
Accelerator Pedal Release Position Learning Procedure. Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds.
How to do the throttle body relearn procedure?
1) Perform the Accelerator Pedal Released Learning procedure. This procedure tells the ECU what voltages to expect when your foot is off the pedal Turn ignition switch OFF and wait at least 10 seconds. Turn ignition switch ON. During the last 10-second period, listen to the throttle body to make sure you hear it moving.
How do you relearn how to drive a car?
Allow engine to idle for at least one minute. Turn the air conditioning on and allow the engine to idle for at least one minute. Release the parking brake. With your foot on the brake pedal and the A/C still on, put the vehicle in “D” (Drive) and allow the engine to idle for at least one minute. Drive the vehicle to complete the relearning process.
How to perform Ford idle relearn you MPT performance?
Turn the air conditioning on and allow the engine to idle for at least one minute. Release the parking brake. With your foot on the brake pedal and the A/C still on, put the vehicle in “D” (Drive) and allow the engine to idle for at least one minute. Drive the vehicle to complete the relearning process.
The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM). Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.
Why is my Nissan Almera not starting properly?
If the problem persists, change the battery of the key, close the doors and open them, and only then start the engine. Lastly, it might be the fuel pump that is failing, the top dead centre sensor or even the oxygen sensor. When repairing the radiator, some connectors from the cooling fans were damaged.
What does the p2138 Nissan accelerator pedal sensor circuit do?
P2138 NISSAN Description. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM.
How much does it cost to repair a Nissan accelerator pedal?
The cost of diagnosing the P2138 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. The Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly.

What was the Nissan Almera like in 2000?
The 2000 model year car changed the way we perceived the Almera. Gone was the gawky styling and uninspired interior. In its place was a car that was confident and mature with a far more European feel and fit and finish to rival anything emerging from Germany.
