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 p2138 mean on a powertrain control module?
I have dealt with a stored code P2138 on many occasions and I have found that it means the powertrain control module (PCM) has detected a discrepancy in the voltage signal between a particular throttle position sensor (TPS) and a particular pedal position sensor (PPS). D/E refers to a particular circuit, sensor, or area of a particular circuit.
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 should I do if my p2138 freeze frame stops working?
Repair or replace defective wiring or components as required and retest the DBW system. Use the scanner to retrieve all stored trouble codes and write them down for future reference. You may also want to keep any related freeze frame data. Your notes may prove helpful if the P2138 is intermittent. Clear the codes and test drive the vehicle.
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 causes the p0138 OBD-II trouble code?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream. What causes the P0138 code?
What does the p2138 Chevy app sensor mean?
P2138 Chevrolet Meaning. The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5-volt reference circuit and a low reference circuit for each of the sensors.
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 do you need to know about the p2135 code?
Cost of diagnosing the P2135 code. P2135 is a diagnostic trouble code (DTC) for “Throttle/Pedal Position Sensor/Switch A / B 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 are the causes of a p2138 code?
P2138 causes can include: 1 A failing, faulty, or dirty APP or TP sensor 2 A faulty, bad, loose, or disconnected APP or TP sensor connector 3 Faulty or damaged APP or TP sensor wiring or circuits 4 Incorrect dielectric grease used on the APP or TP sensor connector 5 A computer issue
What causes p2135 code throttle / pedal Pos switch?
Potential Causes of P2135 DTC. It’s been my experience that the wiring connector or “pig tail” on the throttle body gives problems in the form of a poor connection.The female terminals on the pigtail corrode or pull out of the connector. Possible bare wire on pigtail shorting to ground.
What are the TP sensors on a p2135 Chevy?
P2135 CHEVROLET Meaning The throttle Position (TP) sensors 1 and 2 are potentiometer type sensors each with 3 circuits. – A 5 – volt reference circuit. – A low reference circuit. – A signal circuit The TP sensors are used to determine the throttle plate angle for various engine management systems.
What is the Nissan Versa code p2138 code?
All tested well. replaced… 2007 nissan versa code P2138 ran the diagnostic trouble tree.. All tested well. replaced APP sensor same issue, had noticed app sensor 1 and app sensor 2 are reading the same voltage .7v off throttle 4.5v depressing throttle.
Where is the p2138 reduced power Bulletin located?
The P2138 trouble code may be stored in the computer along with a check engine light. The P2138 Reduced Power bulletin applies to the following vehicles: 2005-2011 GM Passenger Cars and Light Duty Trucks (Including Saturn) The P2128 trouble code refers to Accelerator Pedal Position (APP) Sensor 1-2 Correlation.
What does trouble code p2128 mean on a GMC Sierra?
The P2128 trouble code refers to Accelerator Pedal Position (APP) Sensor 1-2 Correlation. Do NOT assume you have a bad accelerator pedal sensor. GM says the condition is caused by water leaking into the body harness connector that carries the APP signal to the PCM. The water changes the voltage readings from the APP.
P2138 Chevrolet Meaning. The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5-volt reference circuit and a low reference circuit for each of the 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.
All tested well. replaced… 2007 nissan versa code P2138 ran the diagnostic trouble tree.. All tested well. replaced APP sensor same issue, had noticed app sensor 1 and app sensor 2 are reading the same voltage .7v off throttle 4.5v depressing throttle.
When does the p2138 accelerator pedal position sensor run?
P2138 code – This diagnostic runs continuously when the following conditions are met: With the ignition on, battery voltage greater than 10.4 volts, no accelerator pedal position (APP) sensor 1 DTCs present, no accelerator pedal position (APP) sensor 2 DTCs present.
