hi , do you think if I replace crank sensor will solve the problem ,my jeep .... Where's the crankshaft located in 99 jeep grand Cherokee laredo .

CRANKSHAFT POSITION SENSOR LOCATION FOR 4.0L ENGINE IS ON TRANSMISSION BELLHOUSING AT THE LEFT REAR OF THE ENGINE. FOR 5.2L ENGINE CRANKSHAFT SENSOR LOCATED ENGINE BLOCK BEHIND THE RIGHT CYLINDER HEAD.

4.7L ENGINE CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK ABOVE THE STARTER. ON THE 4.0L ENGINE CRANKSHAFT SENSOR LOCATED TRANSMISSION BELL HOUSING AT THE LEFT REAR OF THE ENGINE. THE 5.2L 5.9L CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK BEHIND THE RIGHT CYLINDER HEAD.

It will be on the opposite side of the throttle,where the throttle cable hooks up

The camshaft position sensor is located inside the distributor. It is a hall effect swich, simply remove the distributor cap and the rotor and you can lift it out, unplug and replace.
Have fun but beware a bad crankshaft position sensor can cause a false cam sensor code to be set sometimes.
Good luck.

If you do not know what the codes are, it is O2 sensor. This means the computer is not reading the right information from the faulty sensor. (there is a set range the sensor is meant to show, if one goes over or under the computer shows check engine). The diagnostic is not too bad, give the car a tune up, plugs, wires etc. and replace the O2 sensor. This normally clears up any problems. Let me know if you need further clarification or help.

it is located at the back of the engine on top of the transmission bell housing,the plug runs over to the passenger side of the engine bay and it comes out from behind the engine,you can actually get your hand on the sensor itself from under the hood on the drivers side,and i believe its a 13mm bolt holding it in,the new sensor will have a sticker on the end of it...leave it there,it is used for correct spacing between the sensor and the flywheel,hope this helps

Its not unusual for the crankshaft sensor to intermittanly fail. The crank sensors are not real expensive and are not extremely hard to change.
The Crankshaft Position Sensor (CKP) is mounted into the engine block above the starter motor. Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a Hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it.
Below is a pic of the sensor location.
Good luck.
Regards,

left rear of engine block,on transmission bell housing.best way from top under brake booster use a wrench,

it will be located on the throttle body
