Where is the knock sensor for a 93 cavalier located?
The knock sensor for the 1993 Chevy Cavalier is located in the back of the motor. It can also be located in the engine valve.
What does the engine code knock sensor mean?
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This code may show up intermittently or the Service engine light may be lit constantly. You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms. * The knock sensor is faulty and needs to be replaced * There is a wiring short/fault in the knock sensor circuit * Check the resistance of the knock sensor (compare it to factory specs) * Check for broken/frayed wires leading to the sensor * Replace the knock sensor
Where is rough road sensor in a saturn vue?
The Right Front ABS wheel speed sensor is also used as a rough road sensor to assist the knock sensor in dectecting weather there is a knock from engine or bump from the road in order to adjust the spark and fuel.
What is the tapping noise in your engine 2005 Nissan Quest?
Most likely cause-valvetrain noise, check oil level, pressure, also possible engine knock. If you have a knock sensor, mil should be illuminated
Where is the knock sensor located on a 1999 Mazda Millenia 2.5 engine?
Most knock sensors are located in the block on the firewall side. Should be the only sensor with two wires in the block. It will also have a camshaft position sensor as well. Hope that helps. I am not educated on Mazda engines.
If your knock sensor goes out how would your car run?
You would probably hear a spark knock or pinging under acceleration or load. Check engine light may come on also.
Is a knock sensor the same as an af sensor?
No, it is not a knock sensor at all. An AF (Air/Fuel Ratio) sensor is also know as a wide range oxygen sensor. It is the newer type oxygen sensor.
Can a bad knock sensor cause the car do start bad?
A knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. More details: A knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. The knock sensor responds to spark knock caused by Pre-detonation of the Air/Fuel mixture. As the flame front moves out from the spark plug ignition point, pressure waves in the chamber crash into the piston or cylinder walls resulting in a sound known as a knock or ping. This is caused by using a fuel with a low octane rating, overheating, or over advanced timing. Sometimes it can be caused by hot carbon deposits on the piston or cylinder head that raise compression. A knock sensor is comprised of Piezoelectric materials; Crystals that when impacted, generate a voltage (same idea as a BBQ ignitor). This voltage is monitored by the computer, and when an irregularity is detected, the computer corrects timing in VVT (variable valve timing) engines, or triggers a DTC Diagnostic Trouble Code) in older vehicles.
95 Villager is stalling on the go but when restarted goes good for some time Code says knock sensor 34 Is it really a knock sensor problem How do you change it Where exactly is it located?
Also you can remove the front oxgyen sensor and drive it. If the problem goes away it is probably your catalytic converter. The dealer replaced mine because the van has less than 80000 miles on it.I have a 2000 and I tried to get around replacing the knock sensor. I replaced fuel injectors, wires, plugs, distributor and some other parts. All this helped, but van still lose power and surges after engine hot. I been told after all this that the knock sensor retards timing and causes the fuel not to burn as it should. It not only senses knock, but is a protective device for the engine. I just purchased one on eBay for $65 and will install later this week. Should have replaced it when I first got the code.AnswerThat does not sound like a knock sensor problem. the knock sensor senses "knocks" in the engine and retards the timing accordingly. The knock sensor should not affect stalling, the problems are probably not related. The knock sensor itself is located under the lower manifold. It is a lot of fun to get to.
What does code P0327 for Pontiac grand prix stand for?
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.SymptomsYou may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms. CausesPotential causes for a P0327 DTC include (but are not limited to): The knock sensor is faulty and needs to be replacedThere is a wiring open/short/fault in the knock sensor circuitThe PCM/ECM has failedPossible SolutionsVerify the resistance of the knock sensor (compare it to factory specs)Inspect for broken/frayed wires leading to the sensorCheck the wiring and connections leading to/from the knock sensor and PCM/ECMVerify proper voltage is reaching the knock sensor (e.g. 5 volts)Verify proper grounding of sensor and circuitReplace the knock sensorReplace the PCM/ECM
Your 94 wrx wont boost or rev past 4500 rpm th odd time when its cold it will boost and it runs greatthe engine warning lights on its also runnin the high octain fuelcan the knock sensor cause this?
I guess the knock sensor could cause this,anything is possible, but I have never seen a knock sensor do anything like this. The first step is it get your vehicle hooked up to a Subaru scan tool, and get the engine light fixed.
Where is the Location of camshaft sensor on 4.3 liter engine?
It is located in the same place as a 350ci Chevrolet engine. The 4.3, also known as the "Three-Quarter Three-Fifty" (because it is just a 350ci block with 2 cylinders shaved off), generally has it's cam sensor underneath the driver's side exhaust manifold. Depending on the year, you may find a knock sensor there instead, and the cam sensor will be between your firewall and engine block. Not sure what year 4.3 you have but if it has a distributor, that would be the cam sensor.
