Will a knock sensor cause a fail emissions?
Answer: Although the knock sensor trouble codes have not trigged the check engine light on (yet) they will cause a smog check failure if the codes exist within the ECU during the smog inspection.
How do I fix code P0328?
What repairs can fix the P0328 code?
- Repairing or replacing the knock sensor wiring harness.
- Replacing bank 1 knock sensor 1.
- Replacing a faulty ECU.

- Repairing an overheating engine.
What causes knock sensor High voltage?
Possible Causes Damaged knock sensor connector. Open or shorted to ground knock sensor circuit. Shorted to voltage knock sensor circuit. Loose knock sensor.
What does knock sensor high input mean?
The knock sensor (KS) is mounted in the engine and is used to detect spark knock. When there is spark knock or pinging, the sensor produces a voltage signal that is sent to PCM. P0328 stands for knock sensor high input. This means the PCM has detected a problem with the knock sensor or its circuit.
Can bad gas cause knock sensor code?
A knock sensor is used to detect engine knocking or pinging, which results from abnormal combustion in the engine cylinders. If left unchecked, this bad combustion could ruin parts of your engine. Engine knock can also be cause by bad fuel, so if you hear it, try getting better gas next time.
What is knock sensor for?
The knock sensor identifies the high-frequency engine vibrations characteristic of knocking and transmits a signal to the ECU. The aim is to obtain the maximum energy yield by starting ignition as early as possible. Engines with a knock sensor can reduce fuel consumption and increase torque.
How much does it cost to replace a knock sensor?
The average cost for a Knock Sensor Replacement is between $297 and $380 but can vary from car to car.
What voltage does a knock sensor produce?
When knock occurs, the sensor will produce about spikes from 0 – 4.5 volts (depending on severity of knock). You can lightly tap the area surrounding the sensor to manually test it.
What causes code P0325?
Code P0325 Meaning When the engine “knocks” there is an excessive amount of NOx that is released. When trouble code P0325 is set, this means that the knock sensor 1 in Bank 1 is not operating properly.
What are the symptoms of a bad knock sensor?
The Top Signs of a Bad Knock Sensor. When the knock sensor fails, it will usually cause one or more noticeable symptoms. The most common knock sensor problems include: Illuminated Check Engine Light. The most common sign of a bad knock sensor is an illuminated check engine light.
Why is the knock sensor on Bank 2 not working?
The “B” knock sensor is faulty and needs to be replaced There is a wiring short/fault in the knock sensor circuit Check the resistance of the knock sensor on bank 2 (compare it to factory specs) Check for broken/frayed wires leading to the sensor Replace the knock sensor on bank 2
What is the DTC code for knock sensor?
Throwing DTC codes P0300 (misfire), P0449 (EGR Solenoid), P0330 (Knock Sensor). It’s also giving me the “Check Fuel Cap” message… Hi all I have a ’99 gtv ph2 with the 3.0 v6 24v 220hp The car in real cold runs well, but passed 2 min in idle she begins to fault.
Why do I get less mileage with a bad knock sensor?
If you notice that you’re getting fewer miles per gallon than you normally do, then a bad knock sensor could be contributing to that. Again, there are many reasons for why you might get bad fuel mileage.
