It happened once along with the VSA light and <!> light but all but the CEL were off when the car was turned back on afterwards. APP sensor A is for the primary control, and APP sensor B is a back-up of APP sensor A in case it malfunctions. P2138 The Accelerator Pedal Position (APP) sensor is built into the accelerator pedal sensor assembly and has 2 sensor circuits: VPA (main) and VPA2 (sub). 37 V. APP sensor A is the primary control, and APP sensor B is a back-up of APP sensor A in case it malfunctions. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Confirmed the wiring is correct (read multiple places where wiring may need to switch on one circuit. I asked around several dealerships. 70 V with a fully pressed pedal. 63 volt for greater than 1 s or for a cumulative time of 4 s. Other possible causes include circuit issues and problems with the powertrain control module (PCM). When the voltage difference The document discusses DTC P2138 related to the accelerator pedal position (APP) sensor. Symptoms of a P2138 Code. 4 volts, no accelerator pedal position (APP) sensor 1 DTCs present, no accelerator pedal position (APP) sensor 2 DTCs present. An illuminated Check Engine Light on your dashboard could mean that your PCM has detected a T P or APP sensor malfunctioning that could affect your vehicle’s performance. Commonly known as a "Drive By Wire" setup. This sensor is a non-contact type sensor and uses Hall-effect elements in order to yield accurate signals even in extreme driving conditions, such as at high speeds as well as very low speeds. When the ECM detects a discrepancy or inconsistency between the signals from these two sensors, it triggers the P2138 code. The flagged code is P2138 which represents a bad throttle position sensor. 06 volt. CONSULT screen terms (Trouble diagnosis content) DTC detecting condition P2138 APP SENSOR (Throttle/pedal position sensor/s Other materials: C1609 I replaced the APP with a new genuine sensor and it didn't fix it so I took the part back and replaced it with another genuine APP sensor with no luck. In the 1990's automotive manufacturers began industry-wide The Accelerator Pedal Assembly contains 2 Accelerator Pedal Position (APP) sensors. Sensor/Switch Testing. The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM). Parameter Normal Range: APP Sensor 1 0. 3 second.

Voltage obtained with the formula given below is 0. The cause of this fault code could be a faulty APP sensor, an open or shorted APP sensor harness, a poor electrical connection DTC P2138: APP Sensor A/B (Throttle Position Sensor D/E) Incorrect Voltage Correlation. The Accelerator Pedal Position Sensor (APPS) is responsible for sending a signal I have a 2003 Sentra Se R throwing a p2138 code this is after replacing the APP sensor/assembly. DTC P2138: Accelerator pedal position (APP) Sensor A/B (Throttle Position (TP) Sensor D/E) Incorrect Voltage Correlation. 6. OBD2 Code P2138 indicates a voltage discrepancy between the throttle and pedal position sensors, which can affect acceleration response. 04 V when APP sensor 1 is greater than 1. The APP sensors provide a signal voltage that changes relative to the pedal position. Engine Control Module (ECM) – Monitors APP and TP sensor signals to control the throttle motor; The ECM expects the APP and TP sensor voltages to correlate with each other. The engine starts and runs but when you try to accelerate your Chevy TrailBlazer (GMC Envoy), it accelerates very slowly. This water intrusion results in a voltage difference between APP Sensor 1 and APP Sensor 2 that exceeds a predetermined value for more than a calibrated period of time, setting P2138. Turn engine runs but cannot get out of 'limp' mode - no throttle response for my DBW. P2128 The APP sensor 2 voltage is greater than 4. Home HondaP2138 Honda DTC P2138 Make: Honda Code: P2138 (II) one of these conditions must be met for at least 300 milliseconds: (1) APP sensor B voltage exceeds the range from 0 V or less to 0. When the ECU detects that the signals from the throttle position sensors do not correlate, it triggers the P2138 code. Looks exactly the same as the original one, but is brand new. 4 volts, no accelerator pedal position (APP) sensor 1 DTCs present, no accelerator pedal Code P2138 Buick Description. Perform "Accelerator Pedal Released Position Learning". Here are some of the general steps a mechanic would take to diagnose the cause of P2138: 1.

The CEL and VSA lights came on, and the car ended up in limp mode but I got home safely. Save Share It threw two codes, both pointed to the APP sensor, one saying low voltage and i forgot what the other indicated. ) Its pretty common to need an APP when you get the P2138 . P2128: Accelerator Pedal Position (APP) Sensor 2 Circuit High Voltage. Of these issues, the PCM is usually the least likely unless there is a TSB for your engine and model year. After some reading, it seems the Accelerator Pedal Position Sensor (APPS) is usually the culprit for P2138. 5-Volt Reference 1. 17 V. The technician may observe DTC P2138 - Accelerator Pedal Position (APP) Sensor 1-2 Correlation set as Current or in History. The Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly. It is triggered when the inputs from APP1 and APP2 sensors disagree on the position of the The P2138 code indicates a problem with the correlation between the two accelerator pedal position sensors in the vehicle. The APP sensors are mounted to the accelerator pedal assembly and are not serviceable. Check APP sensors 1 and 2 for resistance values; Refer to TSBs 07-06-04-019A and 07-06-04-019 for similar issues; Possible throttle body issue P2138 is set when APS 2 output voltage which is not 1/2 of APS 1 output voltage is detected for more than 0. Not to worried about that one being bad. The symptoms of this issue may include a lack of response from the accelerator pedal or a decrease in engine power. There are 2 pedal position signals in the sensor, APP and APP2, which have a positive slope but are offset and increase at different rates. 37 V or more when the APP sensor A voltage is 0. The sensor detects the accelerator position and sends a signal to The P2138 error code is related to the throttle/pedal position sensor/switch “D”/”E” voltage correlation. 5. Check for good tension and corrosion. P2138: Accelerator Pedal Position (APP) Sensor 1 - 2 Correlation. The symptoms of this fault code include a lack of response from the accelerator pedal or a sudden loss of power while driving.
