The Chevy Silverado 1500 has two knock sensors. These sensors play an important role in detecting any engine noises caused by early detonation and adjusting the ignition-timing accordingly. When a knock is detected during the combustion process, the knock sensor retards the timing to prevent engine damage.

What happens when a knock sensor goes bad?
Once your car detects the bad knock sensor, you will see your vehicle losing its power. It depends on the octane limit of any engine that how much it will lose from its power. Loss of power halts and even diminishes the timing. Overall, the performance of the vehicle is stopped.
What will bad knock sensor make your truck do?
If the knock sensor isn’t working, the ECU can’t tell if it’s got the right mix of air and fuel in the cylinder. To protect the engine, the ECU will hamper the ignition timing, protecting the engine from unnecessary damage but removing the oomph from the engine.
How do you know which knock sensor is bad?
The most common sign of a bad knock sensor is an illuminated check engine light. When the PCM detects a problem with the knock sensor or its circuit, the module will turn on the check engine light and store a corresponding diagnostic trouble code (DTC) in its memory.
What to do after replacing knock sensor?
After replacing a knock sensor, the vehicle may still be getting an error code from on-board diagnostics. Check the part has been fitted correctly and calibrate the new part using the diagnostic tool. If there’s still an issue, test the parts and connections for potential causes of the problem.
How much does it cost to replace a knock sensor on a Silverado?
Labor costs are estimated between $92 and $116 while parts are priced between $75 and $93. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
What happens if a knock sensor goes bad?
Once your car detects the bad knock sensor, you will see your vehicle losing its power. It depends on the octane limit of any engine that how much it will lose from its power. Loss of power halts and even diminishes the timing. Overall, the performance of the vehicle is stopped.
How do I know if I need a new knock sensor?
A check engine light on your dashboard is the most typical sign of a malfunctioning knock sensor. In the worst scenario, it may also cause an engine to knock or blow, but more frequently, you’ll notice symptoms like engine power reduction and high fuel economy.
What does a knock sensor do on Silverado?
A knock sensor is a small device that detects abnormal vibrations and sounds coming from the engine block and sends a signal to the engine control unit (ECU) to adjust the ignition timing accordingly. This helps prevent pre-ignition or detonation, which can cause serious engine damage if left unchecked.
Will a bad knock sensor throw a code?
Knock sensor failure will not trigger SES light but will store an error code.
