What does the p2138 sensor on a Nissan mean?
P2138 NISSAN Meaning The Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM). Accelerator pedal position sensor has two sensors.
When to use the trouble code p2138 on a computer?
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. Additional trouble codes may accompany this code which further identify the problem.
What is the p2138 code on a Pontiac Grand Prix?
Hi all, I have a 2007 Pontiac Grand Prix with sunroof which is throwing code P2138. This has been going on for nearly a year now. When driving in rain or very wet road conditions the Reduced Engine Power message will come on along with the check engine.
Is there an ec-449 for DTC p2138?
YES >> Proceed to EC-449, “Diagnosis Procedure”. If DTC P2138 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Is applicable DTC detected?
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.

When do I get a p2138 problem code?
The P2138 trouble code is triggered when there are problems with the throttle/pedal position sensor/switch. However, it’s not the only code related to the throttle body and its circuitry. The P2135, P2136, P2137, P2139, and P2140 DTCs also indicate issues in the same areas.
What does the p1238 code on a throttle sensor mean?
Code P1238 indicates that the signals from the two throttle position sensors (or two accelerator pedal position sensors) do not correlate. What Does the P2138 Code Mean?
What is the p2138 code on a Nissan?
I used a code reader and it came up as P2138, “Throttle/Pedal Pos Sensor Voltage Correlation DTC” so I inspected the accelerator pedal sensor, it all looks extremely clean, no cracking in the wires or warping or anything. I’ve attached pictures. So I’m wondering could it be something else ? I’ve ordered the pedal sensor its about $200.
When does p2138 come on on a Pontiac Grand Prix?
Hi all, I have a 2007 Pontiac Grand Prix with sunroof which is throwing code P2138. This has been going on for nearly a year now. When driving in rain or very wet road conditions the Reduced Engine Power message will come on along with the check engine. This only happens when wet and never on dry da…
