How does the TPS work on a Nissan p0120?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts.
What causes a p0120 TPS a circuit malfunction?
Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage.
What is the p0120 TPS signal voltage at WOT?
When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is outside of normal operating range, P0120 will set. NOTE: The PCM knows that any large change in throttle position means a cooresponding change in manifold pressure (MAP).
What are the p0120 and p2135 codes?
I have 2 codes P0120 and P2135, I first replace the pigtail and TPS sensor same problem and codes (Reduced engine power). so i bit the bullet and replaced the throttle body along with another new TPS (it came attached ) still same problem…any help?… codes P0340 and P0120 please help!
What does p0120 mean on the TPS sensor?
P0120 Meaning. The throttle position sensor (TPS) responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM).
What causes a p0120 code on a throttle return?
Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing Bad TPS Bad PCM
What causes a throttle position sensor to malfunction?
Malfunction is detected when an excessively low or high voltage from the sensor is sent to Engine Control Module (ECM). The throttle position sensor ( TPS) responds to the accelerator pedal movement.
How much does it cost to diagnose p0120 Toyota code?
The cost of diagnosing the P0120 TOYOTA 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. When is the P0120 TOYOTA code detected?
Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing Bad TPS Bad PCM
What causes p0120 Nissan throttle position sensor to be faulty?
P0120 NISSAN Possible Causes Faulty Throttle Position Sensor Throttle Position Sensor circuit is open or shorted Throttle Position Sensor poor electrical connection What does this mean? First diagnose P0120 NISSAN code Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors.
What does the OBD code p0120 stand for?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor’s expected range, or is chattering when compared to TPS sensor circuit B.

What are the symptoms of the p0120 OBD-II trouble code?
The ECM detected that the output from TPS sensor circuit A went outside of the specified voltage range in relation to TPS sensor circuit B. The TPS sensor circuit A output falls below .2 volts or goes above 4.5 volts. What are the symptoms of the P0120 code?
What is the OBD code for a TPS sensor?
P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor’s expected range, or is chattering when compared to TPS sensor circuit B.

When does a TPS sensor indicate a problem?
If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc. Other TPS sensor and circuit related DTCs: P0120, P0121, P0122, P0123, P0124
Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage.
How to troubleshoot the throttle position sensor ( TPS )?
Testing the throttle position sensor (TPS) to see if it has failed and causing a TPS diagnostic trouble code (DTC) is not hard. In this tutorial, I’m gonna’ show you how to troubleshoot the throttle position sensor (TPS) on your Nissan 3.3L Pathfinder (Frontier, XTerra or QX4), with a multimeter and in a step-by-step way.
What is the Nissan throttle position sensor part number?
Enter your VIN for the most accurate results. We offer a full selection of genuine Nissan Throttle Position Sensors, engineered specifically to restore factory performance. Please narrow the TPS Switch results by selecting the vehicle. Part Number: 22620-58Y00 Other Name: Throttle Position Switch.
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.
How much does it cost to fix Nissan p1705 code?
The cost of diagnosing the P1705 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. Engine Light ON (or Service Engine Soon Warning Light)
