Best Automotive Replacement Detonation Sensors in 2022

Last update: December 2, 2022

Are there two knock sensors?

Can low oil cause knock sensor?

If your car's knock sensor is malfunctioning, it could be due to low oil levels. The knock sensor is responsible for detecting engine knocking and adjusting the ignition timing to prevent it. If there's not enough oil in the engine, the knock sensor won't be able to do its job properly.

Can you run a car with no knock sensor?

No, you cannot run a car with no knock sensor. The knock sensor is responsible for detecting engine knocking and sending a signal to the engine control unit to adjust the ignition timing to prevent engine damage.

Does knock sensor affect idle?

The knock sensor is designed to detect engine knocking and send a signal to the engine control unit. This helps the ECU to adjust the ignition timing to avoid engine damage. However, if the knock sensor is not working properly, it can cause the engine to idle poorly.


NewYall Pack of 2 Knock Detonation Sensors w/Connector Wire Harness Pigtail Review:


Installing aftermarket components on a Toyota with which I've had trouble in the past gave me some cause for concern. This 2002 Avalon has no longer displayed the check engine light after I fitted the knock sensors and harness. For less than one-fourth the cost of dealer parts.



Beck Arnley 158-0917 Knock Sensor Review:


Dear Amazon, I just wanted to provide a positive review of this knock sensor. Beck Arnley components have always been reliable to me. For my 2004 Honda CRV, I buy only high-quality parts. Still drives like new after 186,000 miles. With this review, I hoped to repay the Amazon Community for everything they've done for me. As a result, I have a few suggestions for any beginners out there trying to complete the work themselves. 1 Before attempting to separate the electrical clip from the old K sensor, thoroughly spray it with electrical cleaner. 2 Use an electrical cleaner spray to clean the connector's interior before reconnecting the new K sensor. 3 New K sensors shouldn't be tightened any more than you would a mountain bike tire to a "nice and tightly snug" condition. I used the wrench you can see in my photos and completed the task in about an hour and a half. The old knock sensor can be unscrewed once it has been loosened if you have a smaller hand and can reach up between the starter and manifold. With my feet on the front tire of the driver's side vehicle and my left hand free, I kind of pushed my body up to get my arm up there. I'm a little small, and the car was on jack stands as well. I'm explaining this because, for whatever godawful reason, I was completely unable to get my right arm up there. And while I was inside the car, there were times and places when I didn't think it was even feasible to manually remove the old knock sensor! So if you're attempting to accomplish something yourself, bear that in mind. Since "Knock Sensors Rarely Go Bad On These Hondas," according to numerous web accounts, the knock sensor might be anything else, I say BULL and recommend changing the sensor to ensure that the check engine light is turned off. In order to save money by doing your own job instead of paying a mechanic who is attempting to enjoy a great holiday with your hard-earned money, I hope I have helped someone out there. Or charging you $100 for a task that they can complete in five minutes. What companies generally charge customers these days is regrettable. Keep in mind that nothing can ever be taken from you. And believing is knowing. My brothers and sisters, have faith and KNOW GB.



Genuine GM 12601822 Knock Sensor Wire Review:


An pricey gadget for what it seems to be, but I wouldn't replace knock sensors any other way because it takes so much time and is so laborious. I thought about using the old knock sensor wiring harness, but I'm glad I got the new one in addition to the sensors because one of the old sensor nipples broke off in the old harness when I removed it. If I had tried to save money for what turned out to be a full weekend's worth of work in replacing sensors, I would have kicked myself. With the additional sensors and wires, the wiring harness is a high-quality product, and the car performs significantly better on hills and under load.

This is a great harness, which I used when I chose to replace the knock sensors while I was changing my oil pressure sensor. I don't worry that water will leak underneath it, and I didn't RTV-seal my knock sensors either. Unless you don't use the foam cushions underneath your intake manifold, which you should because it is their intended usage, you are not need to. This has seen a lot of use and is flawless; there are no problems, and it fits exactly like the original. Nice part, great purchase!



Doicoo Ignition Knock Detonation Sensor 30530-P2M-A01 for Acura RL 3.5L 1996-2004 Honda Civic 16.L 1996-2000 Review:


On my 2000 Civic EX, I had the P0325 error code. I've read that purchasing a non-Honda part won't solve the problem. The code has been turned off so far, and I don't anticipate it returning. Now a few weeks have passed.Given the extremely harsh conditions where the sensor and harness are housed, I assume those who are experiencing problems are actually dealing with wiring problems rather than problems with the sensor itself.

I purchased this to replace the KA24DE knock sensor in my 240sx, which was beyond repair. I discovered that the overheating problem with the car was caused by the timing being significantly advanced. I replaced this in the hopes that the timing advance would be caused by the sensor not reading knock because I was already beneath the intake dealing with the effects of my overheating problem. Although I was unable to determine whether the sensor was the problem, I have been using it for roughly 300 miles and have never experienced a problem with timing moving too far. On a turbocharged engine, where you have to be extremely careful to avoid knock, I might be hesitant to use this sensor, but you can use a NA engine with confidence. I'm definitely content.

For my Ford truck, the knock sensor is a great deal. also quick shipment.



YUNDA Ks197 Engine Knock Sensor for Honda,Acura 30530-PNA-003, 30530-PPL-A01 Review:


I purchased this from Amazon. It arrived in its original box and was covered in plastic, however the plastic was little dusty and stretched from a garage. Two months ago, I installed some on my truck, and they are without a doubt the best product I've ever installed. These are what my f150 has, and I genuinely wouldn't buy anything else. Please note that I am aware that there are better products available at significantly higher prices, but I am not a race car driver on a closed course, and neither are half the people who run them, so that's their choice. However, for my money, I refuse to buy off-brand junk or really expensive items that gained their reputation by spending money on advertising rather than research. Instead, I usually opt for mid-priced items like these, and I think these are a real find.

It worked perfectly; my 5.3 stopped making any pinging noises or having knock sensor errors.


How do you fix detonation?

Detonation is a knocking noise that you'll hear coming from your engine. It's caused by the air/fuel mixture in the cylinders detonating too early. This can be caused by a few different things, but the most common cause is using lower octane fuel than what your car requires. If you're using the correct fuel and you're still hearing detonation, there are a few other things you can check. First, make sure your spark plugs are in good condition. Old or fouled spark plugs can cause detonation. Next, check your engine's timing

How long does it take to replace a knock sensor?

It usually takes about two hours to replace a knock sensor. This includes time to remove the old sensor and install the new one.

How many knock sensors are there?

There are two knock sensors on most engines. One is located on the front of the engine near the cylinder head and the other is located on the back of the engine near the firewall.

How much does it cost to have a knock sensor installed?

If your car is experiencing knocking or pinging sounds, especially when under load, it may be time to install a knock sensor. Knock sensors are designed to detect these sounds and send a signal to the engine control unit to adjust the timing. This can help prevent engine damage caused by knocking. The cost of a knock sensor will vary depending on the make and model of your car. Expect to pay between $100 and $200 for the sensor itself, plus labor costs of around $100.

How often should you replace knock sensor?

The knock sensor is a vital part of the engine management system, and it is responsible for monitoring engine noise. If the knock sensor detects knocking, it will send a signal to the engine control unit (ECU) to adjust the ignition timing. How often you need to replace the knock sensor depends on the make and model of your vehicle, as well as your driving habits. However, it is generally recommended that you replace the knock sensor every 30,000 miles or so.

Is a knock sensor worth replacing?

A knock sensor is worth replacing if your car is knocking. A knock sensor is a sensor that detects knocking and sends a signal to the engine computer to adjust the timing to prevent engine damage.
