Nissan Frontier Throttle Position Sensor

Nissan Frontier Throttle Position Sensor: Some Problems You'll Notice When It Goes Bad

Just like the other sensors located all over your truck, the Nissan Frontier throttle position sensor sends information to the engine's computer regarding the position of the throttle. The engine's computer then uses the data it received to adjust the fuel-to-air ratio to achieve the proper combustion. If the sensor fails, the engine will become noticeably rough and out of timing. If you notice that the engine is starting to become suspect to these symptoms, then you should inspect the throttle position sensor immediately. Here are some of the other issues you might encounter:

Rough acceleration

When you feel that the acceleration of your pickup truck feels rough or hesitant, a possible culprit could be a faulty Nissan Frontier throttle position sensor. Although there are different parts that may cause the same problem, you should still check the throttle position sensor since the engine relies on the sensor to provide the fuel mixture needed for combustion. To check if the sensor is indeed the culprit, you should use a multimeter to check if the sensor still has the right voltage.

Bad performance of a new vehicle

Another symptom you might encounter with a faulty Nissan Frontier throttle position sensor is a bad overall performance of a new vehicle. You might assume that this problem should not happen since the vehicle is new and fresh from the factory. However, the throttle position sensor of new vehicles is normally adjusted with a slight difference of 1/100 of a volt. If you notice that your car is affected by this adjustment, then you have to inform the dealership immediately, so that the setting of the sensor can be corrected.

Uneven idling or sudden stalling

Some other symptoms of a faulty Nissan Frontier throttle position sensor are uneven engine idling and sudden stalling of the car engine. Like the other symptoms previously mentioned, these problems are mainly caused by the wrong throttle position data sent by the sensor to the engine's computer. If the check engine light comes when you experience any of these symptoms, then you should inspect the engine immediately to prevent further damage to the vehicle.

  • Achieve a Well-Performing Engine with a Good Nissan Frontier Throttle Position Sensor 27 February 2013

    The throttle position sensor of your Nissan Frontier is a crucial part in the engine's performance because it monitors the position of the throttle and sends out this information to the engine control unit. Although the sensor has a long service life, it's not completely free from any malfunction or wearing down. Despite of that, you can prolong its life with the proper maintenance. Listed below are some tips you can easily in your own garage:


    Remove the throttle position sensor correctly.


    Whether you want to test or clean your Nissan Frontier throttle position sensor, or you already need to replace it with a new one, you have to remove it properly from your truck's engine. What you need is the right size of screwdriver that should fit exactly to the screw of the sensor. If the screw is too hard, then use a pair of pliers to turn the screwdriver. You can also use an impact drill and the right size of drill bit if it still doesn't work. When the screws are all removed, locate the wires that connect the sensor and unplug each wire carefully.


    Test the sensor at least once a year.


    Testing your Nissan Frontier Throttle position sensor at least once a year is a good preventive maintenance that could help avoid unexpected problems. You can easily test the sensor using a voltmeter. But before you do this, you should unplug the electrical connector of the sensor and turn on the vehicle's ignition switch. Connect the voltmeter to the supply of the sensor and the contact of the signal wire. You should open and close the throttle plate manually and observe if there's a reading at the voltmeter. If there's low or no resistance, then it means that the sensor needs to be replaced.


    Clean the throttle position sensor periodically.


    Dirt and grime that has accumulated on the surface of the Nissan Frontier throttle position sensor can be removed using a cleaning solvent and a soft cloth. After you've applied the solvent, make sure that it has dried completely, and don't allow the solvent to reach the electrical wiring of the sensor because it will cause damage.
