What is the OBD II fault code p2127?
What is the OBD II fault code p2127?
OBD II fault code P2127 is a generic code that is defined as “Accelerator pedal position (APP) / Throttle position (TP) sensor/switch E – low input”, and is set when the PCM (Powertrain Control Module) detects an abnormally low input voltage from the sensor, switch, or circuit in the throttle control system that is labelled “E”.
What are the possible causes of p2138 code?
P2138 Possible Causes 1 Accelerator Pedal Position Sensor harness is open or shorted 2 Accelerator Pedal Position Sensor circuit poor electrical connection 3 Faulty Accelerator Pedal Position Sensor 4 Faulty Electric Throttle Control Actuator
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 p2127 stand for in throttle control?
Thus, if the PCM detects that an abnormally low input signal voltage is present in the throttle control system, it will recognize that the sensor, switch, or circuit labelled “E” is operating outside of acceptable or allowable limits and it will set code P2127, and illuminate a warning light as a result.
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 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.
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.
