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.

The crankshaft position sensor is behind the catalytic converter, in the area where the engine mates to the transaxle. Access is from below, and you should wait for it to cool down. This answer is specific to the DOHC 2.0L Zetec engine.

It tells the ecm where #1 cyl is and when to fire the plug and the injector.

it is at the back of the motor there is a slot in the transmission top side it reads off the flex plate that the covertor bolts to On an automatic trans equipped truck it is under the trans dipstick behind the right cylinder head.

Weather Station is a device that collects data related to the weather and environment using many different sensors. Weather stations are also called weather centers, personal weather stations, professional weather stations, home weather station, weather forecaster and forecasters.

A puller is best .

Most cam sensors are attached with a single bolt.

just a matter of locating the sensor, removing the wire to it then unbolting it.

Refitting is the reverse of the above.

It attaches to the timing chain cover on the front(pass side) of the engine. It is the three wire sensor above the serpentine belts.

Yes there is a crankshaft sensor

I would recommend checking your distributor or coil packs depending on what you have.

Plug wires and plugs.

A clogged fuel filter would be the most likely suspect.

check your mass air flow sensor

I have heard that the newer ones are mounted behind the harmonic balancer. On my 92 3.1 it is mounted in the engine block on the rear bank, driver side. Back near where the trans mounts to the engine. You'll have to get under the car to see it.

if you have a code w/ cam to crank reference then yes. if only a crank sensor issue the no

Under hood, driver side, upper engine area, mounted on end of engine block

There are several temperature sensors on the S-10. Are you talking about the Intake Air Temp (IAT)or MAT (Manifold Air Temp) sensor? are you talking about the Coolant Temp Sensor (CTS)? Are you talking about the Exhaust Gas Temp (EGT) sensor? The IAT/MAT is on the intake manifold before the throttle body. The CTS is on the front of the engine in the thermostat housing. The EGT (if equipped) is on the exhaust manifold close to the head. (So's the O2 sensor)

where is the crankshaft position sensor on a 2004 maxima

The sensor reads from the flywheel so look to the back of the engine or the front of the transmission bellhousing to find it.

the cam positioning sensor is located on the front of the engine block, above the harmonic balance pulley. easiest to get at this from underneath the vehicle,and to change the snsor, nothing else needs to be removed to get at it.

The sensor is located up under the car, look near the oil filter, you will see both sensors

t

Older engines, not overhead cam, it goes in from the front of the motor and you need to put in new bearings with the cam. Overhead cam is under the valve cover and is held in place with caps that bolt on. Take the timing belt pulley off the front, hold tension on it so that the timing doesn't jump, remove the caps and lift out the cam shaft.

It does not have 1.
