Q:will a crankshaft sensor cause a engine to stall at times while driving also what else could cause the engine to stall while driving .
A:The Crankshaft Position Sensor is usually a two wire sensor: a signal and a ground. The Crankshaft Position Sensor consists of (usually) a permanent magnent sensor that is mounted in front of a reluctor wheel mounted to the crankshaft. As the reluctor wheel passes in front of the crank sensor, an A/C signal is produced that varies according to engine speed. The PCM (powertrain control module) uses this A/C signal to interpret engine RPM. Some crank sensors are hall-effect sensors instead of permanent magnent sensors. These are three wire sensors, provided with voltage, ground, and signal. They too have a reluctor wheel with vanes and windows that change the voltage signal to the PCM, providing a RPM signal. The crankshaft reluctor has a specific number of teeth and the PCM can determine the position of the crankshaft using only this sensor's signature pattern. The PCM uses this sensor to also determine cylinder misfires by measuring the reluctor teeth locations in the Crankshaft Position Sensor signal. In conjunction with the Camshaft position sensor the PCM can determine timing of spark and fuel injection. If the PCM senses a loss of Crankshaft Position Sensor signal (RPM signal) even momentarily, P0336 may set. SYMPTOMS: Intermittent stalling & no start, No start, MIL (Malfunction Indicator Lamp) illumination, Intermittent misfire. CAUSES: Bad crank sensor, Broken reluctor ring (missing teeth, debris lodged in ring), Reluctor ring dislodged/stripped from it's stationary location, Wiring harness chafing causing short, Wiring open in Crankshaft Position Sensor circuit. POSSIBLE DIAGNOSIS: Crankshaft sensor problems are at times intermittent and the vehicle may start and run for some time until problem occurs. When engine stalls or if the engine will not start and continue to run, then crank engine while observing RPM reading. If there is no RPM reading, check for a signal coming out of the crank sensor. Using a code reader or the tachometer to check for RPM signal. Visually inspect the Crankshaft Position Sensor harness for damage or cracking in the wiring insulation. Repair as necessary. Make sure the wiring isn't misrouted near high voltage spark plug wires. Check for loose connection or broken lock at the sensor connector. Repair as necessary. Obtain a resistance specifications for the Crank sensor. Remove and check it. If it doesn't pass, replace it. If it checks out okay, check the reluctor ring for damage, broken teeth, or debris lodged in the ring. Make sure the reluctor ring isn't dislodged. It should be stationary on the crankshaft. Carefully repair/replace as necessary. If the vehicle intermittently stalls and after stalling you have no RPM signal and you have verified the wiring to the Crankshaft Position Sensor is good, then try replacing the sensor. If that doesn't take care of it, Consult a local auto mechanic that specializes in the particular manufacturer of vehicle being driven to secure the parts and labor in order to get the vehicle running properly. Avoid employing used parts for integral engine components as they have a greater chance of failure than newer equipment. For compatibility of this part with your vehicle, please provide your vehicle make, model and engine specification.
Q:will a crankshaft sensor cause a engine to stall at times while driving
A:When a crankshaft sensor has failed or is failing, certain timing problems will arise in engine function. The engine may start normally in some cases, but will cut off after a few minutes (or seconds) of operation. More than likely the engine will be unable to start at all. Since the crankshaft sensor is responsible for engine timing, the driver may experience engine backfire or irregular rpm function, if the vehicle starts at all.
Q:where do is it located
A:For further assistance, please provide the year, make, model and engine size of your vehicle
Q:Where is this located on 91 dodge b250 ram van
A:On alot of vehicles, this sensor is usually located towards the front of the motor near the crankshaft sensor. For a more accurate location for your specific vehicle, I recommend stopping by your local Advance Auto parts store and picking up a Haynes repair manual for your vehicle or speaking with a representative at the store.

Q:Where is this located on a Dodge 3.9lt V6 1993 modle
A:To better assist you with the location of this part I recommend refering to a repair manual such as Haynes repair manuals for your vehicle which can be purchased at your local Advance Auto Parts store. These manuals can give you all the information you need to replace this part as well as step by step instructions on how to do so.
