<\/span><\/h2>\n\n\n\nCan I drive without the knock sensor?<\/h3>\n\n\n\n
The car will be able to be driven without a knock sensor, but it is not advised. Not having a working knock sensor will mean the engine control unit will not be receiving the information it needs to manage the engine and maintain maximum efficiency.<\/p>\n\n\n\n
Not having a working knock sensor will also mean you will have no way of knowing if an engine knock is developing. An efficient engine knock sensor will allow you to take the vehicle to a mechanic if the engine light comes on and carry out any work necessary to resolve the issue.<\/p>\n\n\n\n
Can you replace a knock sensor yourself?<\/h3>\n\n\n\n
It is possible to replace an engine knock sensor yourself by following the steps provided above. It is advised that you have some experience with vehicle maintenance to ensure the sensor is installed correctly.<\/p>\n\n\n\n
If you have any concerns, you can check the sensor after installation by following the advice further up in this article, or you can take it to a mechanic who will be able to check it quickly.<\/p>\n\n\n\n
Alternatively, if you don’t feel you have the experience to carry out the work, taking it to your mechanic will ensure the sensor is fitted, and your engine receives all the information it needs to run efficiently.<\/p>\n\n\n\n
What happens if you don’t replace the knock sensor?<\/h3>\n\n\n\n
Your engine sensor is there to detect sounds or vibrations that can indicate problems. The engine control unit uses the information it gets from sensors like this to control the ignition timing so it can maximize fuel mileage and engine power.<\/p>\n\n\n\n
A sensor that doesn’t work will not be able to detect these sounds or vibrations, and the ECU will have to revert to default values, impacting your fuel efficiency and the performance of the vehicle.<\/p>\n\n\n\n
Another problem is that the sensor won’t be able to detect pinging in the engine. Pinging in the engine is when the air and fuel mixture ignites incorrectly. This can damage the internal components of the engine and needs to be rectified as quickly as possible.<\/p>\n\n\n\n
Why is a replaced knock sensor still getting code?<\/h3>\n\n\n\n
After replacing a knock sensor, it is possible that the ECU still receives codes that indicate certain problems. After installation, you should clear the diagnostic trouble codes using a scan tool.<\/p>\n\n\n\n
The adaptive learning memory of the ECU can also be reset, so the system works from a blank slate.<\/p>\n\n\n\n
You can also check the wiring to ensure there are no loose or broken wires on the new sensor.<\/p>\n","protected":false},"excerpt":{"rendered":"
