Research on Knock Sensor for Subaru Legacy

Subaru Legacy Knock Sensor

An engine that sputters or strains at speed or while carrying loads, poor acceleration and a sudden uptick in gas station visits are all potential signs that your knock sensor may not be doing its job. This small part acts as an ear to the engine control unit (ECU), detecting unusual pulsations or sounds that may indicate pre-ignition problems.

At PartsGeek.com you will find top-quality Subaru Legacy knock sensor models from Bosch, Hitachi, Beck Arnley and Standard Motor Products. Our team prides itself on offering an incredible parts selection at steep discounts. Our excellent customer service, speedy delivery and 30-day return policy help us to make certain you get the part you're looking for.

What is a knock sensor?

A part of fuel delivery system, the knock sensor is able to detect sub-audible engine sounds that may indicate an issue with the combustion process. When the sensor reads abnormal pings or knocking, signs of pre-ignition, it communicates that data to the engine control unit (ECU). The ECU responds by slowing engine timing to prevent it. Pre-ignition refers to the premature combustion of the air/fuel mixture outside of the optimal space within the cylinder.

How much is a replacement Subaru Legacy knock sensor?

The price of a new Subaru Legacy knock sensor will depend on your car's model year and the manufacturer. Most of the sensor units available on PartsGeek.com cost between $40 and $80.

What are some symptoms of a failing knock sensor?

Because the knock sensor operates as part of the fuel delivery system, a malfunctioning unit will effect engine performance. You may notice unusual sounds from the engine compartment, sluggish acceleration and a sudden drop in fuel economy. Noises and performance issues will be especially obvious at higher speed and when carrying heavy loads.

How can I prevent problems with the knock sensor?

Unfortunately, if your knock sensor has already begun to cause performance problems you will need to replace the part. To prevent issues, you can regularly test your sensor using a voltmeter or multimeter to confirm electrical continuity.

So far so good, the check engine light went away after installation....very good value at parts geek.

2000 Subaru Legacy Knock Sensor

Very Satisfied
Reviewer: subdoc

This is the second knock sensor that I have ordered through PG . The first was MOE (Hitachi) and this one was not but both appear to be working well.

1998 Subaru Legacy Knock Sensor

Very Satisfied
Reviewer: Right part easy install all fixed

This knock sensor was the right fit all is good thanks parts geek

2006 Subaru Legacy Knock Sensor

Very Satisfied
Reviewer: OEM part.

Compared with my cracked one, seems to be the same part in every way. Knock sensor warning hasn't come on, so it seems to be working, though I found out my main knocking noise was because my car needed an octane boost(and I used some cheap gas I don't think it liked). But, product is good. Partsgeek shipped it out the same day, which was cool, too.
