Remove and replace the crankshaft position sensor on a 2005 Dodge Viper 8.3L V10, including electrical connector disconnect and sensor mounting bolt removal.

Warnings

⚠Allow engine to cool completely before beginning work. The sensor is mounted near exhaust components and can be extremely hot.

⚠Do not force the sensor during removal or installation. The housing can crack, and the O-ring groove can be damaged.

ℹ️Battery disconnect is not required for this procedure, but ensures no inadvertent cranking during work.

Preparation

Ensure vehicle is parked on level ground with parking brake engaged
Allow engine to cool completely if recently operated
Disconnect negative battery terminal if desired for additional safety
Raise front of vehicle and support on jack stands for easier access (optional but recommended)

Procedure

1
Locate the crankshaft position sensor
The crankshaft position sensor is mounted at the rear of the engine near the bellhousing area, positioned to read the crankshaft tone/target wheel. Verify the exact location against the factory service manual for the 8.3L V10. Use a flashlight to identify the sensor body and electrical connector. Access is best achieved from underneath the vehicle.
2
Disconnect the electrical connector
Locate the electrical connector attached to the crankshaft position sensor. Depress the locking tab on the connector body and pull the connector straight off the sensor. Do not pull on the wiring harness itself. If the connector is difficult to release due to corrosion or age, use needle-nose pliers to carefully depress the tab while pulling.
3
Remove the sensor mounting bolt
Using the correct socket and extension, remove the single mounting bolt securing the crankshaft position sensor to the engine block. Verify the bolt head size against the factory service manual. The bolt threads into the block behind the sensor body. Keep the bolt for reinstallation.
4
Remove the crankshaft position sensor
Grasp the sensor body firmly and pull straight out from the engine block. The sensor may be tight due to the O-ring seal. Use a gentle twisting motion while pulling if resistance is encountered. Do not pry against the sensor body or engine block. Once removed, inspect the sensor tip for damage, metal debris, or excessive wear.
5
Clean the sensor mounting bore
Use a shop towel to clean the sensor mounting bore in the engine block. Remove any old O-ring material, oil residue, or debris. Inspect the bore for damage or cracks. The bore should be clean and dry for proper sensor seating.
6
Prepare the new sensor
Inspect the new crankshaft position sensor to confirm it matches the original. Verify the O-ring is properly seated in the groove on the sensor body. If the O-ring is supplied separately, install it onto the sensor body, ensuring it is fully seated in the groove. Apply a light coat of clean engine oil to the O-ring to aid installation.
7
Install the new sensor
Insert the new crankshaft position sensor straight into the mounting bore in the engine block. Push firmly until the sensor body seats flush against the block mounting surface. Do not twist or cock the sensor during installation, as this can damage the O-ring. The sensor should slide in smoothly with hand pressure.
8
Install and torque the mounting bolt
Thread the mounting bolt by hand into the engine block through the sensor mounting tab. Once hand-tight, use a torque wrench and the correct socket to tighten the bolt to the factory specification (typically around 7 ft-lbs / 105 in-lbs for a small sensor bolt — verify against the service manual). Do not overtighten, as this can crack the sensor housing or strip the threads in the aluminum block.

9
Reconnect the electrical connector
Push the electrical connector onto the crankshaft position sensor until the locking tab clicks into place. Tug gently on the connector to verify it is fully seated and locked. Ensure the connector body is not hanging on any sharp edges or heat sources.
10
Reconnect battery and clear codes
If the negative battery terminal was disconnected, reconnect it and tighten securely. Start the engine and verify it runs smoothly without hesitation or rough idle. Use a scan tool to clear any diagnostic trouble codes that were set prior to sensor replacement. Perform the crankshaft position sensor relearn procedure with a compatible scan tool if required by the PCM for this vehicle.

Reassembly

If vehicle was raised, lower it from jack stands after verifying all connections are secure
No disassembly of other components was required for this procedure

Verification

Start the engine and verify smooth operation with no hesitation, stalling, or rough idle
Use a scan tool to verify no crankshaft position sensor codes are present (P0335, P0336, P0337, P0338, P0339)
Verify the tachometer displays correct engine RPM during idle and acceleration
Road test the vehicle to confirm normal drivability and no check engine light illumination
Inspect the sensor area for any oil leaks around the O-ring seal after initial test drive
