The P0145 is a generic OBD-II powertrain trouble code. Its official definition is “O2 Sensor Circuit High Voltage (Bank 2, Sensor 3)”. This diagnostic trouble code is stored by the vehicle’s Engine Control Module (ECM) when it detects that the signal voltage from a specific oxygen sensor is consistently reading above the normal, expected range. The designation is critical: “Bank 2” refers to the side of the engine opposite the one containing cylinder number 1. “Sensor 3” indicates this is an additional sensor beyond the standard upstream (Sensor 1) and primary downstream (Sensor 2) sensors. Its function and location are vehicle-specific; it is often a secondary monitoring sensor in a complex exhaust system, perhaps after an additional catalytic converter.
The P0144 is a generic OBD-II powertrain trouble code. Its official definition is “O2 Sensor Circuit High Voltage (Bank 1, Sensor 3)”. This code is stored by the vehicle’s Engine Control Module (ECM) when it detects that the signal voltage from a specific oxygen sensor is persistently and abnormally high, typically near the reference or battery voltage level. The sensor designation is key: “Bank 1” refers to the side of the engine containing cylinder number 1. “Sensor 3” is not a standard upstream or primary downstream sensor; it is an additional sensor found in some vehicles, often a secondary downstream monitor.
The P0141 is a generic OBD-II powertrain trouble code. Its official definition is “O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)”.
The P0140 is a generic OBD-II powertrain trouble code. Its official definition is “O2 Sensor Circuit No Activity Detected (Bank 1, Sensor 2)”.
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.
The B0082 fault code is a manufacturer-specific OBD-II code. In General Motors (GM) vehicles, it is authoritatively defined as “Discard Right Front/Passenger Side Impact Sensor (SIS)”.
