Code P0136 Definition Oxygen Sensor Circuit Malfunction (Bank 1, Sensor 2) What Does P0136 Mean? Your car has oxygen (O2) sensors that measure the amount of oxygen present in your exhaust. Based on the measurements taken, the O2 sensor will fluctuate between a high(rich) and low(lean) voltage reading. Your Engine Control Module (ECM) uses the...
Code P0121 Definition Throttle Position Sensor (TPS) “A” Circuit Range Performance Problem What Does P0121 Mean? Your TPS “A” Circuit has an expected output voltage range, as does your TPS “B” Circuit (if so equipped). When code P0121 occurs, it means that your Engine Control Module (ECM) recognized that your throttle position “A” circuit’s expected...
Code P0332 Definition Knock Sensor 2 Low Circuit Input (Bank 2) What Does P0332 Mean? Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged....
Code P0345 Definition Camshaft Position Sensor Circuit Malfunction What Does P0345 Mean? The camshaft position sensor located in the internal combustion engine monitors the position and rotational speed of the camshaft. It works hand in hand with the reluctor ring that creates a square wave voltage signal that the ECM interprets as the camshaft position....
Code P0335 Definition Crankshaft Position Sensor “A” Circuit Malfunction (Bank 1) What Does P0335 Mean? Crankshaft position is used to inform the Engine Control Module (ECM) of when it is time to spark and deliver fuel. It works hand in hand with the reluctor ring that creates a square wave voltage signal that the ECM...
Code P0325 Definition Knock Sensor 1 Circuit Malfunction (Bank 1) Code P0325 Meaning Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged. When the...
Code P0330 Definition Knock Sensor 2 Circuit Malfunction (Bank 2) Code P0330 Meaning Knock sensors are solely used for the purpose of sensing when your engine is “knocking,” or sensing when there is exploding in the air/fuel mixture in a way that delivers less power and can also damage the engine if prolonged. When the...
Code P0496 Definition EVAP Flow During a Non-Purge Condition What Does P0496 Mean? The Evaporative Emission Control (EVAP) System seals the fuel system of the vehicle in order to prevent fuel vapors from the fuel tank and fuel system from escaping into the atmosphere. This is important because fuel vapors contain a variety of hydrocarbons....
Code P0021 Definition Intake Camshaft Position Timing- Over-Advanced (Bank 2) What Does Code P0021 Mean? The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft(s) is(are) adjusted by the ECM through the use of an oil control valve(s) (OCV) also...
Code P0011 Definition Intake Camshaft Position Timing- Over-Advanced (Bank 1) What Does Code P0011 Mean? The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft(s) is(are) adjusted by the ECM through the use of an oil control valve(s) (OCV) also...
