What does the throttle position sensor do on a Nissan Maxima?

The throttle position sensor (TPS) is a crucial component of the engine management system on your Nissan Maxima. It’s job is to tell the PCM how much the throttle plate opens and closes (as you step on or off the accelerator pedal) so that the PCM can calculate how much more (or less) fuel to inject.

How does the TPS work on a Nissan Leaf?

• The TPS contains a closed throttle position switch (CTPS) and a variable output throttle position sensor. • This procedure uses the closed throttle position switch (CTPS) status (ON or OFF) instead of the throttle position sensor (variable output voltage) to adjust the TPS.

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 do you set the accelerator pedal on a Nissan?

1. Make sure that accelerator pedal is fully released. 2. Turn ignition switch ON and wait at least 2 seconds. 3. Turn ignition switch OFF and wait at least 10 seconds. 4. Turn ignition switch ON and wait at least 2 seconds. 5. Turn ignition switch OFF and wait at least 10 seconds.

Where is the accelerator pedal position sensor located?

The accelerator pedal position sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the ECM.

Why did my Altima 2.5L not start up?

My 2013 altima 2.5L could not start an engine. It turned on P0101 and P2119. After replacing an air filter and cleaning MAF and throttle body, it seemed that everything is fine. However, in the next day, ECM set P0101 again. I replaced MAF filter and PCV valve, but it could not solve my problem.

What does ECM set p0101 and p2119 by?

It turned on P0101 and P2119. After replacing an air filter and cleaning MAF and throttle body, it seemed that everything is fine. However, in the next day, ECM set P0101 again. I replaced MAF filter and PCV valve, but it could not solve my problem. So, I have taken some experiments for 1 week, in order to confirm what the conditions set P0101 by.

How does the ECM work on a Chevy truck?

Every Chevrolet truck has an engine control module that manages the electronic components of the engine and monitors sensors for errors. Returning the ECM to its factory state may be necessary to troubleshoot or resolve a number of problems. Step 1 Remove the nut from the negative battery cable using a socket set or wrench.

How to install a new throttle position 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.

What causes a bad mass air flow ( MAF ) sensor?

This problem occurs mainly when the MAF sensor gets dirty and has a contaminated wire. The easy fix is to have the sensor cleaned by a technician. 3. Engine Does Not Start Properly When turning on the ignition, if your car does not start immediately, it may be due to a bad mixture of air and fuel.

How to replace a mass airflow sensor in a car?

In most vehicle models, all you have to do is: 1 Disconnect the part of the air intake duct that connects to the MAF sensor. 2 Carefully unplug the sensor electrical connector. 3 Unscrew two or more sensor mounting bolts. 4 Remove the old sensor. 5 Install the new one.

What does trouble code p0100 mean on MAF sensor?

The mechanic will use a scan tool to check what trouble code is retrieved. The trouble codes from P0100 to P0104 all indicate that something is wrong with the mass air flow sensor. The trouble code P0171 and P0174 are also caused due to a damaged or faulty mass air flow sensor.

When do you need to replace the throttle position sensor?

As soon as you see a mix of these throttle position sensor symptoms, you should test the TPS and if it isn’t functioning properly, it needs to be replaced. Unfortunately, a TPS cannot be repaired as it is a tiny sensor but the good news is that a new sensor “usually” isn’t too expensive so you can get back on the road soon enough.

Why do I need to troubleshoot my MAF sensor?

You can hardly diagnose a MAF sensor on symptoms alone. Other faulty components, like the fuel pump, fuel pressure regulator, and vacuum system, can create similar symptoms. That’s why you need to troubleshoot the MAF sensor (and related circuits as needed) before replacing components. 2. How the MAF Works

How can I adjust the throttle position sensor?

You’ll really need the service manual for the exact voltage spec, as well as the correct wires to connect up to. This type of sensor is usually set with the ignition on, engine off. So, armed with your service manual and proper tools, adjusting the throttle position sensor should lead to a better running, more efficient engine.

Can a bad throttle position sensor cause a car to shake?

A bad throttle position sensor can cause other issues on your car if left unattended. That’s right! If the sensor is faulty, it will cause your car to shake heavily. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement.

What is the idle switch on a Nissan Maxima?

Now, since the throttle position sensor assembly, on your 1996-1999 3.0L Nissan Maxima, has two connectors (a brown one and a gray one). You need to know that: The brown wiring harness connector connects to the throttle position sensor portion of the TPS assembly. The gray one connects to the idle switch portion of the TPS assembly.

What should I do if my throttle position sensor is bad?

Start your car and test the idle and acceleration. Depending on your vehicle and the sensor you’ve installed, you may need to manually adjust the sensor. Other options automatically adjust to offer your car the optimal levels of air and fuel for a smooth idle and powerful acceleration.

How does a GM throttle body relearn procedure?

A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position.

How is the gas pedal connected to the throttle body?

Many car makers including GM started installing fly by wire electronic throttle bodies. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting.
