Code P0154 Definition O2 Sensor Circuit No Activity Detected (Bank 2, Sensor 1) What Does P0154 Mean? Code P0154 is triggered when your vehicle’s O2 sensor (bank 2, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of...
Code P0117 Definition Engine Coolant Temperature (ECT) Sensor Circuit has lower than normal voltage What Does P0117 Mean? The engine coolant temperature (ECT) sensor monitors the fluctuations in the temperature of the engine coolant. This data is sent to the ECM, which uses this data to regulate the air to fuel ratio, cooling fans, and...
Code P0118 Definition Engine Coolant Temperature (ECT) Sensor Circuit has higher than normal voltage What Does P0118 Mean? The engine coolant temperature (ECT) sensor monitors the fluctuations in the temperature of the engine coolant. This data is sent to the ECM, which uses this data to regulate the air to fuel ratio, cooling fans, and...
Code P0137 Definition O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) What Does P0137 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the air-fuel ratio coming out of the catalytic converter to ensure the catalytic converter is functioning properly. The powertrain control module constantly flip-flops...
Code P0022 Definition “A” Camshaft Position – Timing Over Retarded (Bank 2) What Does P0022 Mean? The variable valve timing system increases fuel economy and engine performance by regulating the timing of both the intake and exhaust valves. The camshaft is adjusted by the ECM through the use of the oil control valve (OCV). The...
Code P0012 Definition “A” Camshaft Position – Timing Over Retarded (Bank 1) What Does P0012 Mean? The variable valve timing system increases fuel economy and engine performance by regulating the timing of both the intake and exhaust valves. The camshaft is adjusted by the ECM through the use of the oil control valve (OCV). The...
Code P0443 Definition Evaporative Emission Control System Purge Control Valve Circuit Malfunction What Does P0443 Mean? The evaporative control (EVAP) system collects raw fuel escaping from the fuel tank. This information is then communicated to the ECM which regulates the emissions of the vehicle. The P0443 code is set when the ECM detects a malfunction...
Code P0057 Definition H02S2 Heater Control Circuit Low (Bank 2, Sensor 2) What Does P0057 Mean? The HO2S2 (heated oxygen sensor 2) sensor calculates the air to fuel ratio of the vehicle’s exhaust. The P0037 code is set when the ECM detects that the HO2S2 on bank 2 has a malfunctioning heater element. The heater...
Code P0037 Definition H02S2 Heater Control Circuit Low (Bank 1, Sensor 2) What Does P0037 Mean? The HO2S2 (heated oxygen sensor 2) sensor calculates the air to fuel ratio of the vehicle’s exhaust. The P0037 code is set when the ECM detects that the HO2S2 on bank 1 has a malfunctioning heater element. The heater...
Code P0521 Definition Engine Oil Pressure Sensor/Switch Range/Performance What Does P0521 Mean? The oil pressure sensor calculates the oil pressure of the vehicle’s engine. This is then communicated to the ECM in the form of a voltage value. The P0521 code is set when the ECM detects the voltage value is either higher or lower...
