What is the P0327 fault code? What does it signify?
A range of sensors are installed in your vehicle to collect all types of information. One of them is the “Knock Sensor” This is used for detecting vibrations and knocks which could cause damage to the engine. P0327 is one fault code that can be associated with a faulty knock sensor. The knock sensor is designed to notify the PCM when there are unexpected engine sounds. This fault code can indicate a more serious problem.
Pre-programmed into Powertrain Control Module (PCM / ECM/ECU) are the minimum and maximum frequencies of noise the engine will make. A knock sensor related fault code is set when the PCM finds that the frequency exceeds the expected value. A P0327 fault code is set if the knock sensor in bank 1 generates a very low voltage signal (probably less than 0.5V). This code could appear and disappear infrequently.
Other knock sensor-related fault code codes are P0326,P0328,P0329,P0329,P0329,P0329,P0329,P0330,P0330,P0331,P0332,P0333, andP0334.
What Are the Possible Causes of P0327 Fault Codes?
- – Defective knock sensor
- – Connectors or circuits that fail to detect knock sensors
- – Defective EGR system
- – Damaged cooling systems
- – Incorrect air-fuel combination
- – ECU/ECM/PCM rarely defective
What are the symptoms for P0327 Fault Code Symptoms?
- – Illumination for check engine light
- – Engine hums and rattles during acceleration
- – Engine speed fluctuations
- – Sometimes there may not be any symptoms.
How to Fix the P0327 Fault Code
The resolution of a Code P0327 depends on two factors: the trigger code and the make/model of your vehicle.
- – Check the resistance of your knock sensor and compare it to the factory specifications.
- – Inspect the wires connecting to the sensor for frayed or broken wires
- – Refer to wiring and connections between knock sensor and PCM/ECM.
- – Verify that the appropriate voltage is reaching the knock sensor (eg, 5 volts).
- Verify that the circuit is properly grounded.
- – Replace knock sensor
- – Replace PCM/ECU
