The P0117 is a generic OBD-II (Onboard Diagnostics II) trouble code. Its official definition is “Engine Coolant Temperature (ECT) Sensor Circuit Low Input”.
Fault code P0115, applicable to all vehicle manufacturers, indicates “Engine Coolant Temperature (ECT) Sensor 1 Circuit Malfunction”.
Fault code P0113 is a generic OBD-II diagnostic trouble code defined as “Intake Air Temperature Sensor 1 Circuit High Input” . This indicates that the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected that the voltage signal from the Intake Air Temperature (IAT) Sensor 1 is higher than the expected normal operating range, typically indicating an open circuit or high resistance in the sensor circuit.
Fault code P0114 is a generic OBD-II diagnostic trouble code defined as “Intake Air Temperature Sensor 1 Circuit Intermittent”. This indicates that the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an inconsistent, sporadic, or erratic signal from the Intake Air Temperature (IAT) Sensor 1 circuit.
Fault code P0112 is a generic OBD-II diagnostic trouble code defined as “Intake Air Temperature Sensor 1 Circuit Low Input” . This indicates that the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected that the voltage signal from the Intake Air Temperature (IAT) Sensor 1 is lower than the expected normal operating range, typically indicating a short circuit to ground in the sensor circuit .
Fault code P0110 is a generic OBD-II diagnostic trouble code defined as “Intake Air Temperature Sensor 1 Circuit Malfunction” . This indicates that the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an abnormal signal from the Intake Air Temperature (IAT) sensor circuit, typically meaning the signal is outside the expected operating range (either too high or too low) .
Fault code P010E is a generic OBD-II diagnostic trouble code defined as “Mass or Volume Air Flow Sensor B Circuit Intermittent/Erratic.” This indicates that the vehicle’s Powertrain Control Module (PCM) has detected an unstable, fluctuating, or sporadic signal from the secondary circuit (“Circuit B”) of the Mass Air Flow (MAF) sensor. Unlike hard circuit faults (low or high), an intermittent fault means the signal is unstable, dropping out, or spiking unpredictably .
