I know that the knock sensor for a 1998 Quest with a 3.0 is located on the passenger side of the engine compartment under the intake manifold. You should be able to find the wiring and connector next to the intake manifold. To access the sensor, you have to remove the upper and lower intake manifold. The sensor is on the block between the heads. Hope this helps.

Is the map sensor the same thing as the knock sensor on a 1999 daewoo nubira and exactly where is it located


Not the same-the map sensor tells the computer how much air is in the intake to compute fuel requirements-map means manifold absolute pressure-look for it on the firewall or attached to engine-small black box with vacuum hoses, or at least one vacuum hose to it coming from the intake plenum.
The knock sensor is located on the engine block somewhere, maybe under the intake, it is for detecting engine "pinging"-or engine knock, the timing will be retarded a scheduled amount if any cylinders exhibit knock.

On my 1991 chevy blazer s10 I get error code 43. What is it and how do I fix it


Hi, the indication is that your computer is not receiving a good signal from the knock sensor. Recommend you check the connector on the sensor and the wire. Also make sure the sensor isn't loose in the block. If those look good, you may want to just replace the sensor. A new one is $30 at autozone. Without the knock sensor signal, the computer will default the ignition timing toward a less fuel efficient value. The sensor looks like the picture below and is mounted in the engine block. You may have 2 knock sensors--one on each side of the engine. Sorry, but I could not find a good picture of the location. I will keep looking for one, though.

I have a 04' Chev, 6.0L. Engine light came on, fault code came up PO332. I'm afraid the KS's are under the intake. Is there any way to test the KS to see if it is bad, or is there another problem that is...


P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Causes for P0332 DTC:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- PCM or ECM failure.

Solutions:
- Repair or resecure the harness or connector.
- Replace the knock sensor.

Your best bet is to just replace the knock sensor for sensor 2 bank 2. Call Auto Zone with part number SU1282 this is the OEM replacement.

The knock sensor looks like this:

Where is the knock sensor located and what does it look like?


Your vehicle is equipped with 2 knock sensors. They are located on the cylinder heads under the intake manifold. They look like the picture below.

NOTE: Most knock sensor codes are caused by mechanical problems with the engine like pullies that are "rattleing" or lifters that are "tapping" etc. The knock sensor does not know the difference between "ignition ping" and mechanical problems like those mentioned. Knock sensor codes set when the engine computer has retarded the ignition timing as far as it can in an effort to stop ignition ping and the knock is still present. This is usually because the problem is not caused by ignition ping.

I sent my honda accord 1993 to honda dealer/repairer to get check why check engine ligths come ON.they said faulty collant sensor/is this serious problem?and why if the check engine ligths comes on,my car...


a bad coolant sensor not a serious problem that can cause engine damage. but it will make it run real bad ,use alot of fuel ,hard start,ruin your cat converter,etc.they arent that expensive and are easy to put in.
think of your coolant sensor like your choke.it tells the computer how warm/cold the engine is and then compuer when it thinks cold gives more gas or hot and gives less gas.if comuter dont know temp of engine it has to guess and they are always wrong.
coolant sensor bad computer has no way of knowing engine temp

P0522 engine code with oil ligth on 2005 SRT 4


By any chance did this start after an oil service. Could be the wrong oil. But my first guess is the wire at the sensor may be loose or the sensor is bad. Oil pressure sensor. Best bet is to have it looked at by a pro because Chrysler has had lots of problems over the years due to oil issues. I'm talking engine destroying oil issues. I'm not saying be concerned but be aware of this in order to make your best decision

My check engine light is on on my 98 nissan 200sx


the knock sensor tells the car's on board computer/PCM that the engine is pinging/knocking from poor fuel or the wrong octane or other engine related faults, they seldom fail, most likely the connector to the sensor is making a poor connection, the knock sensor is located on the engine block, it screws into th water jacket, do u hear any engine ping or spark knock?.
