What Does Code P0110 Mean? DTC P0110 signifies an Intake Air Temperature (IAT) Circuit Malfunction. This code is set by the Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), when it detects that the electrical signal from the IAT sensor is outside its predefined operational parameters, indicating an open circuit, […]

What Does Code P0111 Mean? DTC P0111 indicates an Intake Air Temperature (IAT) Sensor Circuit Range/Performance problem. This signifies that the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected an anomaly in the electrical signal output from the IAT sensor that falls outside the expected operating parameters […]

What Does Code P0112 Mean? DTC P0112 signifies an Intake Air Temperature (IAT) Circuit Low Input. This diagnostic trouble code is set by the Engine Control Module (ECM) or Powertrain Control Module (PCM) when it detects that the voltage signal from the Intake Air Temperature sensor is consistently below a calibrated threshold, typically near 0 […]

What Does Code P0113 Mean? DTC P0113 signifies an Intake Air Temperature (IAT) Circuit High Input. This diagnostic trouble code is set by the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), when it detects an electrical signal from the IAT sensor circuit that is outside the normal operating range, specifically […]

What Does Code P0114 Mean? DTC P0114 indicates that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an intermittent or erratic signal from the Intake Air Temperature (IAT) sensor circuit. Unlike a continuous open circuit (P0113 – high input) or short circuit (P0112 – low input), an intermittent […]

What Does Code P0115 Mean? DTC P0115 signifies an Engine Coolant Temperature (ECT) Circuit Malfunction. This code indicates that the Powertrain Control Module (PCM), often referred to as the Engine Control Module (ECM), has detected an electrical anomaly within the circuit dedicated to the Engine Coolant Temperature sensor. The ECT sensor is a critical component, […]

What Does Code P0116 Mean? DTC P0116 signifies an “Engine Coolant Temperature Circuit Range/Performance Problem.” This code indicates that the Powertrain Control Module (PCM), or Engine Control Module (ECM) in some vehicles, has detected an implausible or erratic signal from the Engine Coolant Temperature (ECT) sensor. Unlike P0117 (ECT sensor circuit low) or P0118 (ECT […]

What Does Code P0117 Mean? DTC P0117 signifies an “Engine Coolant Temperature Circuit Low Input.” This indicates that the Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), is receiving a voltage signal from the Engine Coolant Temperature (ECT) sensor that is abnormally low. The ECT sensor is a thermistor, typically […]

What Does Code P0118 Mean? DTC P0118 signifies an “Engine Coolant Temperature Circuit High Input” condition, as detected by the Powertrain Control Module (PCM), also commonly referred to as the Engine Control Module (ECM). This code is set when the PCM receives a voltage signal from the Engine Coolant Temperature (ECT) sensor that is above […]

What Does Code P0119 Mean? The OBD-II diagnostic trouble code P0119 signifies an Engine Coolant Temperature Circuit Intermittent condition. This code is set when the Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), detects an inconsistent, fluctuating, or erratic signal from the Engine Coolant Temperature (ECT) sensor that does not align […]
