I got the Code P0333 Knock Sensor 2 Circuit High Input (Bank 2). Reset it and didn't come back...yet... Show
Reading about it in the FSM. Seems a  So what does this code really mean? Internal problem? Sensor problem? The real issue is that it: ECM sets ignition timing to maximum retard Any thoughts help! The Check Engine Light flickering on your dashboard is the first noticeable symptom for any engine code, including DTC P0327 and P0332 (both knock sensor error codes.) However, you’ll need an OBD2 scan tool to help determine the exact cause of the lit Check Engine Light on your dashboard. 2. A Pinging Or Knocking SoundIf you have code P0332, the output signal from the knock sensor is too low to signal the ECM when your engine produces a pinging or knocking sound. As such, the ECM doesn’t retard the ignition timing when the air-fuel combusts early, resulting in unresolved engine knocking while accelerating or idling. 3. Sudden Loss Of Engine PowerYour engine losing power is another common sign of a malfunctioning knock sensor or code P0332. A faulty knock sensor may fail to report when the ignition timing is off, resulting in the spark plug igniting the air-fuel mixture late. Due to this delay in combustion, the engine cannot fully burn the air and fuel mixture, resulting in your engine losing power. 4. An Overheated EngineAn overheated engine could result from faulty ignition timing going undetected by a bad knock sensor. However, it could also happen when you have a faulty serpentine belt or engine cooling system. So, it’s best to get a mechanic to diagnose the issue and see if it’s due to the diagnostic trouble code P0332. 5. Increased NOx EmissionsAn engine problem related to the “Knock Sensor 2 Circuit Low Input” error could damage your vehicle’s catalytic converter. With a damaged catalytic converter, your engine cannot convert toxic pollutants into less harmful emissions, resulting in your vehicle failing the emissions test. In some cases, increased NOx emissions could be due to a negative fuel trim caused by a bad O2 sensor. 6. Decreased Fuel EfficiencyA problem in your vehicle’s ignition timing or fuel trim may cause your engine to burn more fuel to propel the vehicle forward, resulting in fuel consumption spikes. While a drop in fuel efficiency could be due to fault DTC P0332, there are many other potential reasons, so you should get your vehicle checked soon. OBD-II Code P0333 is defined as a Knock Sensor 2 Circuit High. It indicates that the PCM has detected a voltage input reading in the knock sensor circuit for a particular cylinder that is not within a predetermined manufacturer’s limit. Typical knock sensor circuits consist of one 5-volt signal wire. If voltage readings exceed a variation of 10-percent from the manufacturer’s reference voltage, a code will be stored in the PCM and a malfunction indicator lamp will be illuminated. The knock sensor tells the engine control module (PCM) that the engine has an excessive vibration resulting from an incorrect fuel and air mixture. If the PCM does not receive a signal from the knock sensor, it will set code P0333. Code P0333 pertains to the sensor on bank 2 (the opposite side of the engine where the #1 cylinder is located). While the P0333 code will not always result in drivability problems, it is important to have it inspected immediately as it may lead to serious damage and higher repair cost. What causes the problem of Knock Sensor 2 Circuit High Input (Bank 2)?
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. |Code P0333 Tech NotesThe P0333 code means that the Knock Sensor is not working properly. Problems with the knock sensor will not cause engine performance problems. Replacing the knock sensor usually takes care of the problem. |What is the Cost to Diagnose the Code P0333?Labor: 1.0The cost of diagnosing the P0333 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. What is Bank 2 knock sensor 2?These sensors simply sense when your engine is “knocking,” a term used to describe when the air/fuel mixture powering the engine combusts too early, which can harm the engine and reduce the available power. This bank of diagnostic codes indicates that there's a problem with the knock sensor 2 in bank 2.
What causes knock sensor high input?Error Code P0328 is defined as Knock Sensor 1 Circuit High Input (Bank 1 or Single Sensor). It means this code refers to a fault in the knock sensor 1 circuit. This trouble code is detected when there is an excessively high voltage from the sensor is sent to Electronic Control Module (ECM).
How serious is a P0333 code?How serious is the P0333 code? While the P0333 code will not always result in drivability problems, it is important to have it inspected immediately. The main reason for this is that the code can be caused by more serious engine problems, which can lead to serious damage and higher repair costs.
What is the knock sensor 2 circuit?It sends a message to the vehicle's computer or powertrain control module (PCM) whenever it detects that one or more of the engine cylinders are knocking. The PCM then uses the information to adjust the ignition timing in order to prevent more knocking.
