Code P0152 Definition Bank 2 Sensor 1 oxygen sensor has an abnormally high voltage reading What Does P0152 Mean? Code P0152 is triggered when the Engine Control Module (ECM) detects an abnormally high voltage (approximately 1.2V or higher) on the signal circuit of the bank 2 sensor 1 Oxygen (O2) Sensor for an extended period...
Code P0452 Definition The evaporative pressure sensor or fuel tank pressure sensor has a low voltage signal. What Does P0452 Mean? The evaporative emission control (EVAP) system prevents fuel vapors from escaping into the atmosphere. This system stores the vapors in a charcoal canister and purges the vapors into the engine to burn them. The...
Code P0715 Definition Malfunction in the transmission input/turbine speed sensor circuit What Does P0715 Mean? Code P0715 is triggered when the Engine Control Module (ECM) or Transmission Control Module (TCM) detects an irregular signal coming from the input/turbine speed sensor in the transmission. The input/turbine speed sensor is used to measure how many revolutions per...
Code P2187 Definition Bank 1 has too much air or not enough fuel at idle. What Does P2187 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When there are more than 14.7 parts air to 1 part fuel in the air-fuel mixture,...
Code P0336 Definition The engine control module, ECM, has detected an improper/irregular voltage coming from the crankshaft position sensor. What Does P0336 Mean? The ECM relies on the crankshaft position sensor to know when to fire the injectors and spark plugs. When code P0336 is set, the ECM is reading an irregular voltage coming from...
Code P0175 Definition Bank 2 has too much fuel or not enough air. What Does P0175 Mean? Combustion engines run most efficiently when they maintain an air-fuel mixture ratio of 14.7 parts air to 1 part fuel. When the upstream oxygen sensor detects there are less than 14.7 parts air to 1 part fuel in...
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...
