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.
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 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.
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 do you need to know about the p2138 code?
Cost of diagnosing the P2138 code. 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.
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.
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 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.
