Question about 2000 Jeep Grand Cherokee
The engine dies but will restart sometimes right away sometimes may take 10 min. Throttle body has been cleaned, plugs changed, fuel filter changed,and injectors cleaned. Started out once in every 2-3 months now does 2-3 times daily. finally got and engine code reading that points to crankshaft position sensor or camshaft sensor. Could it be these or maybe the computer? Sometimes the horn will sound and the headlights will come on and off when someone is walking by or in the middle of the night. 6cyl 2wd 4.0 liter
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.
