The P0332 and P0327 codes are related to the knock sensor circuit. These codes indicate that there is a problem with the signal from the knock sensor or its circuit. A faulty water pump is unlikely to directly cause these specific trouble codes. The knock sensor is designed to detect engine vibrations caused by detonation or knocking, which is unrelated to the water pump's operation. Since you've already replaced the knock sensors, wiring harness, ECM, spark plugs, wires, and coils, and you're still experiencing issues, it's essential to consider other possibilities. Here are a few things you might want to check or consider: Sensor Connections: Ensure that the knock sensors are properly connected, and there are no issues with the wiring connections. Sensor Placement: Verify that the knock sensors are correctly positioned and securely mounted on the engine block. Engine Grounds: Check the engine grounds to ensure there is a solid connection, as poor grounding can sometimes cause sensor issues. Exhaust System: Inspect the exhaust system for leaks, as leaks can affect the accuracy of knock sensor readings. Fuel Quality: Poor-quality or incorrect fuel could potentially lead to knocking issues. Ensure you are using the recommended fuel for your vehicle.

Hi there,
The codes you mentioned are problems pointing to the knock sensors. The trouble code P0332 stands for “knock sensor 2 circuit low input (Bank 2).” It belongs to a range of trouble codes that are triggered by a knock sensor malfunction (P0325 to P0334). A P0332 code gets logged when the PCM receives a reading from the knock sensor that is lower than the voltage specified by the manufacturer.

The other trouble code P0327, points to “knock sensor 1 circuit low input (Bank 1 or single sensor).” This code triggers when the PCM detects low voltage readings from your vehicle’s primary knock sensor circuit. Though symptoms don’t always manifest, the most common symptoms are a lit check engine light, engine pinging on acceleration, and fluctuating engine RPM.

I hope this helps!
