The knock sensor is under the intake manifold, about a $600 repair. However, the knock sensor is never bad even if there is a code that says it is.

Likely you have a MAF sensor coated with varnish. Go here for detailed instuctions

I have a 99 ford f150. Sometimes it runs perfect, then out of no where when I try to accelerate it vibrates bad and becomea hesitant. When I came to a stop I switched threw all gears and it seems like it...


This sounds like you might have a bad plug wire or something else in the ignition system is arcing to ground. A quick way to verify this is to run the truck in Park at idle. Next, spray the ignition wires with Windex. You'll notice the truck starting to rough up and might even see the bad wire arcing to ground. A complete tuneup would be recommended in this case.
I hope this helps! :)

I have a code p0325 knock sensor 1, circuit bank 1 or single sensor problem


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. Knock sensors generally bolt into or thread into the engine block.

This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.

Symptoms: You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.

Causes: A code P0325 most likely means one or more of the following has happened:
* The knock sensor is faulty and needs to be replaced
* There is a wiring short/fault in the knock sensor circuit

Possible Solutions
* 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


Test it and tell us news.

1998 legacy outback. engine light comes on & goes off sporadically, when on, it hesitates at takeoff & runs rough at low speed.


Knock sensor has gone bad most likely. I had the same problem with the same car and replaced the knock sensor. Fixed the problem. Very common with Subarus. It's an inexpensive part but it requires patience and small surgeon's hands to get to it and replace it. Lots of how-to articles on line.

WHEN YOU STOP AT A JUNCTION THE CAR TRIES TO STALL WHEN YOU PRESS THE ACCELIRATER , YOU HAVE TO KEEP REVING THE ENGINE TO GET IT MOVING.ANYONE GOT ANY IDEAS, HAVE BEEN TOLD IT MITE BE A CENSOR BUT NOT...


If your engine tends to idle rough it is probably a sensor. Mine would idle rough and disturb my mass airflow sensor located on top of engine. It may also be a knock sensor from engine knocking.

Knock engine sensor light on truck is hesitating/


Did they replace the knock sensor?Check the wire going to the sensor(knock).Look for a bare place hiting up against something ,grounding it out.Make sure the plug to knock sensor is good.And make sure it is making a good connection,Knock sensors also ground a part of the computer to feed back imformation.This connection is a must,the truck will not perform at all,stumble,miss,and carry on.Sometimes even backfire.If they did not replace the knock sensor,replace it with high quality sensor from NAPA,or oem from dealer.This sensor has to be made perfect,no room for inperfection.The knock sensor is easy to replace,they just screw in a hole in the block.When removing the sensors,nothing will come out such as oil or water,this is a dry threaded hole.It is a bell shaped sensor.If you don`t know which sensor is bad,purchase one.replace one,and if there is no change,replace the other side with the old sensor you just took out,it will be a good one.I hope this helps you,Let us know if it does.

You can take it to Autozone or O'reillys and they will scan the engine for free. They usually will identify the part that is bad from reading the scanner.
It sounds like the EGR sensor for the emissions and a TPS throttle position sensor for the performance. The rough ride could be a 4x4 control because some of the Lincolns will pump up the air suspension harder for the 4x4 setting.

Engine running rough


It sounds like maybe yu have a fuel filter that getting plugged up.
To check this, see if you can remove it from the engine, then very carefully blow thru it in the direction the fuel travels, if clean you should be able to blow thru it easily, if not then replace.
The P132 is (E132) .................. Knock Sensor Circuitry Failure .... The knock sensor is what prevent engine ping from low octane. ...
It could also be you just got some bad gas.
You also might try topping off the tank with gas from another place and bring the octane level up if that is the problem.
Hope this helps
Good luck
