Question about 1998 Dodge Ram 1500 4WD

1 Answer

Crankshaft Sensor What I failed to add in my post was when I bought the motor the flywheel was already on the motor but the magnet was not, I took the one from the old flywheel and mounted it to the new one, I remember there being more than one set of holes to put the magnet in, I think moving it will help, the thing that really sucks is I bought 3 sensors at $90 bucks a piece before I remembered what I told you above, I think if I move it to line up with the marks on the flywheel and crankshaft I will cure the problem, what is your thoughts ? And by the way thanks.......

What ever u mounted fom the old flywheel was not a magnet....the magnet is internal to the cranksensor and the flywheel slots trigger the sensor....whatever you attached maybe causing this code

Was getting gas & spark & now no spark on any plugs


Crankshaft position sensor , possibly !
Crankshaft Position (CKP) Sensor
The crankshaft position (CKP) sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The PCM supplies a 12-volt, low reference, and signal circuit to the CKP sensor. The sensor returns a digital ON/OFF pulse 24 times per crankshaft revolution.
There are a lot of videos on youtube on testing crankshaft position sensors an Cam sensors !

Wheres crankshaft sensor located


which engine,?
why not post symptoms and not guess causes.?
CKP is the SEA.org name for this part.
was introduced in 1996 here. and up to 2006 in other countries.

the 2.0L the CKP sensor is behind the flywheel (must pull transmission and flywheel to get to it)
ive posted the photo of that here, on fixya 5 times. searches work.
or is the engine the V6? 2.5 (H25 H27engine)

did you know the PCM if scanned will report bad CKP every time.!
even cranked?
same is true if the CAM sensor fails, at end of CAM>

the V6 engine the CKP sensor (crank) is at 7pm facing from
of the engine crank pulley housing on front if engine at front of crankshaft.
if have FSM on both engines, if stated.
use a scan tool and see the errors.
the errors will tell you what sensor is failing if in fact they are.
the tool is as cheap as $10

ah heck,
ill do G16g engine too (USA) the CKP sensor is at
6pm below the crank-pulley on the pan flange,
all USA 1996 and newer. not true in other countries.
some have no CKP at ALL, A FACT.

Where is the crankshaft position sensor located on


The CKP sensor, located on the back of the engine, runs off the flywheel/driveplate and provides the ECM with crankshaft position and engine speed. The sensor is a Hall effect type that senses the passing of teeth on a flywheel/driveplate, because the teeth disrupt the magnetic field of the sensor. This disruption creates a pulse generation, which is monitored by the ECM.,,,

How do I set the crank sensor position on the flywheel after it has been removed.?


fly wheel wont change ,the crank position sensor picks up a magnetic puls created when the motor spins past the(CPS) and that reads that the motor is spinning

Changing crankshaft sensor


It's either located by the harmonic balancer or flywheel. Usually small and exposed has a magnetic pickup in the end which registers when a particular spot on the crankshaft passes by it. Hope this helps !

What is the crank shaft sensor?


A crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.
Crank sensors in engines usually consist of magnets and an inductive coil, or they may be based on magnetically triggered Hall effect semiconductor devices. Common mounting locations include the main crank pulley, the flywheel, and occasionally on the crankshaft itself. This sensor is the most important sensor in modern day engines. When it fails, there is a small chance the engine will start (engine will likely cut out after a few minutes of driving) but it mostly will not start.[citation needed]
Some engines, such as GM's Premium V family, use crank position sensors which read a reluctor ring integral to the harmonic balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

I have a 97jgc limited 4x4 5.2 wont start from every post i read it points to crankshaft position sensor but i cant find it on my jeep what is the easiest way to get to it? from underneath or lean over the...


Should be very close to the harmonic balancer that's on the front end of the crank shaft. You will likely have to remove a component and the belt to gain access to it. Good luck.

Crank sensor location


Look around the bottom of cylinder block. Or near where the flywheel is to, because the crank angle sensor works from missing teeth or magnets on the flywheel or a cog/wheel fixed to the crankshaft.Hope this helps

CRANKSHAFT SENSOR


No, no, never move the magnet, replace the sensor, it is most likely setting the code.
