What causes a p0120 TPS a circuit malfunction?

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 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!

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 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 does the code p0122 on the ECM mean?

What Does Code P0122 Mean? Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.

What does code p0122 on a TPS mean?

Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input What Does Code P0122 Mean? Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage.

How to stop a p0302 cylinder 2 misfire?

Place a chock on both sides of the drive wheels of the vehicle Have an assistant get into the driver’s seat and place the shifter in DRIVE with the parking brake set and their foot firmly pressing down on the brake pedal Take up a position alongside the front of the vehicle, so that you can reach the engine, with the hood open and secure

What is the diagnostic code for cylinder 2 misfire?

P0302 is a diagnostic trouble code (DTC) for “Cylinder 2 Misfire Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Why does my Nissan Versa have a misfire code?

Driving with a misfire can damage the vehicle’s catalytic converter. The engine is also not firing all of the fuel, so raw fuel is also passing through cylinder 3 into the exhaust. Mileage may suffer as well when your Versa has P0303. P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code.

What causes Nissan Versa to get a p0303 trouble code?

There are quite a few things that can cause the P0303 trouble code to trigger the Nissan Versa . Here are the most common problems that will throw the code. They are presented somewhat in order from most to least likely to be causing the code: Bad Spark Plugs – Spark plugs are one of the most common causes of P0303.

Where is the cylinder 3 on a Nissan Versa?

An important thing to understand when finding the location of cylinder 3 is that it’s going to be the 3’rd cylinder in the firing order of the vehicle, and not the 3’rd cylinder that you might see when looking at the engine. The P0303 trouble code will trigger the Versa’s service engine soon light. The vehicle itself may begin to run rough.

What does the misfire code p0303 mean?

P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code. An important thing to understand when finding the location of cylinder 3 is that it’s going to be the 3’rd cylinder in the firing order of the vehicle, and not the 3’rd cylinder that you might see when looking at the engine.

What is the DTC for TPS a circuit malfunction?

P0120 is a diagnostic trouble code (DTC) for “TPS “A” Circuit Malfunction”.

What is a trouble code for TPS a?

P0120 is a diagnostic trouble code (DTC) for “TPS “A” Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $70.00.

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?

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.

How does the throttle position sensor ( TPS ) work?

P0120 Description 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 does p0122 mean on a TPS sensor?

A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.

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).
