6.7L Cummins Forum

Can someone tell me exactly where the crankshaft position sensor is located on the 6.7 L?

Truck currently won't start and figured would replace this as a start.

Thanks,

If find where it goes, would you share the location with me. I am on my way to pick one up for my truck and have no clue where it is located. Thanks

Here ya go.

Theory of Operation



The ECM provides a 5-volt supply to the engine crankshaft speed/position sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The crankshaft speed/position sensor provides a signal to the ECM on the crankshaft speed/position sensor signal circuit. This sensor generates a signal to the ECM as the crankshaft speed indicator ring moves past sensor. The ECM interprets this signal into an engine speed reading and determines engine position. The ECM illuminates the MIL lamp immediately after the diagnostic runs and fails. During this time the camshaft speed sensor is used to provide engine speed and position information to the ECM. The customer may experience an engine misfire as control switches from the primary to the backup speed sensor. The ECM will turn off the MIL lamp when the diagnostic runs and passes in 4 consecutive drive cycles.

• When Monitored: With the key on.
• Set Condition: The voltage detected at the Crankshaft position sensor is below a calibrated value.

Possible Causes
CKP SENSOR
(K24) SIGNAL CIRCUIT OPEN
(K824) 5-VOLT SUPPLY CIRCUIT OPEN
(K925) RETURN CIRCUIT OPEN
(K24) SIGNAL CIRCUIT SHORTED TO (K925) RETURN CIRCUIT
(K824) 5-VOLT SUPPLY CIRCUIT SHORTED TO (K925) RETURN CIRCUIT
(K24) SIGNAL CIRCUIT SHORTED TO (K824) 5-VOLT SUPPLY CIRCUIT
(K24) SIGNAL CIRCUIT SHORTED TO GROUND
(K824) 5-VOLT SUPPLY CIRCUIT SHORTED TO BATTERY NEGATIVE
INTERMITTENT CONDITION
ECM

Here's a picture of where the crankshaft sensor on the Cummins 6.7L is located.



Here'sa link to the connector and sensor locations on the 6.7L engine.

Has anyone replaced the crankshaft sensor and fixed the problem? Mine started misfiring and throwing codes a week ago. Now it doesn't want to start sometimes. Looking for feedback before I start down this trail.

The above diagram does not give the "Crankshaft sensor" location. It gives CrankCASE sensor. Is there anyone that can give me the location?
Thanks.

Corrected information on CPS location for a 6.7 engine ..... Located at the front of the engine, driver side, down by the oil pan next to the harmonic dampener ......

For the 6.7, here is the pic of the sensor:


The actual location, front of the engine on the driver side, lower part of the engine next to the oil pan facing the damper:


Closer view from under the engine:


From the top looking down:


Pic are thanks to ClayCountyCummins on another forum, to dang cold outside right to snap these pics.

I wonder why cummins changed this from the 5.9 to the 6.7 ..... Should have realized something seemed wrong when I kept looking at the 6.7 damper and seeing the indexing ring on it and not on the 5.9 ..... Again sorry for the wrong info !

Cheers.
