If you have any questions, please feel free to post a comment below, or post in the. It is held in by a single bolt, and is located on top of the driver's side of the engine, just aft… The knocking sound that the sensor is designed to detect is caused by uneven combustion of a lower octane gasoline than the engine is able to burn efficiently. Here is an example of a sensor that was installed incorrectly: Vs one that was installed at the proper angle: looks familiar don't it? The style has changed a few times, mainly in the connector. Since 1886, Bosch has developed innovative products—including spark plugs, starters, brakes and steering system parts—for the automotive aftermarket. I don't know what the torque spec is on the knock sensor, but I know that it is pretty sensitive to how tight it needs to be and overtightening will break it pretty easy.
Unhook the wire connector by fiddling with the locking clip, and you can remove the sensor from the car. You'll probably strip the threads out before you break the bolt. Once you have completed this, you should be all set but you may need to reset the computer to clear the check engine light. Deep down in this crevice you probably need about 9 inches of extension on socket wrench with a 12mm socket there is a solitary bolt that holds in the knock sensor. Remove the bolt and there's enoug … h wire to pull out and remove the wiring from the sensor.
Instead of one combustion, now you have two. The service manual says to remove a bunch of parts including the intake manifold, but it is really not necessary. Really did make the job a snap! Feels like a sports car to drive! Partly what prompted the write-up. Seems to be like that with a lot of things. ? I'm not a mechanic, so excuse my egnorance. Positioning the new sensor may be the most difficult part due to an inability to … each it effectively but it is possible.
The car runs much more smoothly now because the timing is not being pulled and the gas mileage has nearly doubled. The crank sensor is used to determine misfire codes and any issue that causes an alteration of the crankshaft rotational speed can set a misfire if it occurs multiple times. A knock sensor is like a small electronic microphone that is usually attached to the engine block and listens for a couple of things that a engine might do. What generally goes wrong with this sensor? I just can't ever seem to find the good threads when I need to reference one. Knock or spark knock, is defined in the automotive world as Detonation.
Is this a knock sensor code. Contact us with any questions before installing the parts. I'd suspect maybe less power and fuel mileage possibly until it's corrected. The head of the cable is mated to a small cylindrical barrel, which holds the cable. Knocking, if allowed to continue over a long time can seriously damage the engine.
Make sure to tighten the bolt to no more than 15 ft-lbs of torque or you could ruin it. It is on the top of the engine, drivers side, near the rear of the engine compartment. Designed to meet the exact needs of each specific vehicle, Hitachi knock sensors are the premium choice. I recommend having a socket set with a 12mm socket , plenty of socket extensions, a magnet, a pair or two of pliers, a leaf, and a long skinny screwdriver to accomplish install … ation and removal of this item. Once the bolt seats to the sensor a turn of the wrist with the ratchet is plenty to hold the sensor. I would have purchased an Outback, but was tired of driving wagons.
Any ideas on this subject? You'll have to track down the underlying problem. This will lead to corrosion which you can see thre is already a small amount in the area under the plastic which will cause the sensor to send eratic readings, or no reading at all. The only glitch has been an engine knock sensor that malfunctioned at 70,000 miles and had to be replaced. If you have a larger magnet you can put the magnet on top of your socket wrench if it is metal to retrieve the bolt easily. Make sure you clean up all the debris surrounding the hole, otherwise this wont work!! It has proven to be a very well made and reliable car. You can't chase misfires with a knock sensor code - knock sensors provide feedback that alters ignition timing directly - thus if they are not working it is entirely possible that you may be experiencing misfire codes as a result. The sensor was only 165 bucks while the labour to install was nearly 800.
? The engine spins faster, so the ignition system advances the timing of the spark in order to compensate. And retarded timing equals loss of power and fuel economy. Doesn't say anything about replacing rear O2 sensor, but others with experience may have solved it with that? Knock sensor removal is fairly straightforward on the normally aspirated 1. Push the slack towards the barrel, rotate it about 90 degrees so the cable comes out of the slot, and remove the cable. It's a donut shape the size of a half-dollar or smaller in diameter and a half-inch or so in thickness, if memory serves.
