What is the p2138 code on a throttle body?
Photo of a throttle body, throttle body position (TPS) sensor is the black part to the lower right: The computer monitors the correlation of both voltages. When both voltages agree, the system is functioning properly. When they deviate for two seconds, the code P2138 is set indicating a malfunction somewhere in the system.
When do I find a p0651 sensor reference voltage B circuit open?
When I find a stored P0651 code, it means that the powertrain control module (PCM) has detected an open circuit for a particular sensor; designated in this case as “B”. When diagnosing an OBD-II code, the term open could be substituted for absent.
What does PCM error code p0651 mean?
When Error Code P0651 is stored, this means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) has detected an open circuit for a specific sensor; which in this case is designated as “B”. In diagnosing for this code, the term ‘open’ cold be substituted for ‘absent’.
What is the diagnostic code for throttle / pedal position sensor?
P2138 is a diagnostic trouble code (DTC) for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What should I do if my throttle pedal is not working?
Probe the throttle body connector for power to the throttle motor. Have a helper turn the key on and slightly depress the pedal. If no power is present, the computer is at fault. If there is power the throttle body is malfunctioning. Other throttle related DTCs: P0068, P0120, P0121, P0122, P0123, P0124, P0510, & others.
What happens when you depress the accelerator pedal?
When you depress the accelerator pedal you are pushing down on a sensor indicating the desired amount of throttle opening which is sent to the engine management computer. In response the computer sends a voltage to the electric motor to open the throttle plate.
What does the 2127 on the gas pedal mean?
Not shure what state to check it in but I assume engine off with the ignition on. will keep posted of my progress. the 2127 is actually the accelerator positioning sensor on the gas pedal. it’s a short in the system somewhere. have to see where “E” circuit goes to.
How can I check the accelerator pedal sensor?
Inspect the top cover on the throttle body for cracks or warping. If any are present, call the dealer and ask if they sell just the top cover. If not, replace the throttle body. With a voltmeter, probe the accelerator pedal sensor. It will have 5 volts for reference and next to it a varying signal. Turn the key on and slowly depress the pedal.
What does the code p2138 mean on a Hyundai?
For example, on an Infiniti, the code might be described as a “throttle position sensor circuit range/performance” error, but in a Hyundai, it might be specified as an “electronic throttle control system malfunction power management.” There are several potential warning signs or symptoms of this error code.
Is there a way to fix the p2138 error code?
Do you feel that there is no other choice but to ask Google, “how do I fix trouble code P2138?” Well, thankfully, you have landed on our page, an overview guide which will help you not only understand the P2138 error code and why the check engine light is on but also how to potentially resolve the problem.

What do you need to know about Nissan code p2138?
Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals. 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.
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.
What are the possible causes of p2127 Nissan?
P2127 NISSAN Possible Causes 1 Faulty Accelerator Pedal Position Sensor 2 Accelerator Pedal Position Sensor harness is open or shorted 3 Accelerator Pedal Position Sensor circuit poor electrical connection 4 Faulty Electric Throttle Control Actuator (TP Sensor 1 and 2) 5 Faulty Engine Control Module (ECM)
What does p2125 stand for in OBD-II?
P2125 code definition. P2125 is a general OBD-II trouble code indicating a fault with the throttle/pedal position sensor/switch “E” circuit. This code is similar to many other throttle body and pedal position codes.
Why does my ECM not work on p2125?
P2125 can have some rather serious symptoms. If the ECM can’t detect the signal from the throttle/pedal switch, it may not allow the throttle to work at all. If this occurs, the vehicle will not move at all when the gas pedal is depressed.
What is the new electronic throttle control technology?
The new “electronic throttle control” technology consists of a accelerator pedal position sensor, an electronically controlled throttle body complete with an internal motor, two embedded throttle position sensors for correlation factors and the engine management computer.
What happens when you replace the throttle body?
If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.
How to do the throttle body relearn procedure?
During this period the idle may be higher than normal. It should slowly drop as the engine heats up. Watch the engine temp gauge and note when it reaches operating temp. Then continue to let it idle for an additional 5 minutes. It will continue to adjust idle during this period.
How to reset throttle body calibration [ step by step guide ]?
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.

When does the throttle / pedal position sensor switch D?
It is triggered when the vehicle’s engine control module (ECM) or powertrain control module (PCM) detects that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do not correlate.
Where is the throttle position sensor located on a car?
Prior to this, the vehicle’s throttle was controlled by a simple cable with a direct connection between the gas pedal and the throttle. A throttle position sensor (TPS) is situated opposite the throttle linkage connection on the throttle plate.
