P3368 severity depends on the specific fault. While some causes are minor (e.g., sensor failure), others can affect performance or emissions. Diagnosis is recommended.

Can I drive with P3368?

Short trips may be possible, but prolonged driving with P3368 active is not advised until the root cause is identified and repaired.

Will P3368 clear itself?

P3368 may clear if the fault is intermittent, but it will likely return if the underlying issue is not resolved. Use a scanner to monitor pending and confirmed codes.

P3368 - Crankshaft Position Sensor Circuit High

P3368 is a Diagnostic Trouble Code (DTC) indicating a fault related to Crankshaft Position Sensor. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles. When P3368 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Crankshaft Position Sensor circuit or system.

What is P3368?

P3368 is a Diagnostic Trouble Code (DTC) indicating a fault related to Crankshaft Position Sensor. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles.

When P3368 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Crankshaft Position Sensor circuit or system.

Common Symptoms

Engine hard starting or no start
Stalling unexpectedly
No tachometer reading
Check Engine Light on

Possible Causes

Failed crankshaft position sensor
Damaged reluctor ring
Wiring or connector damage
Sensor mounting or gap issue

Step-by-Step Diagnosis

Connect an OBD2 scanner and confirm the code is present. Note any additional codes.
Review freeze frame data to understand engine conditions when the code was set.
Visually inspect the Crankshaft Position Sensor and related wiring harness for damage, corrosion, or loose connections.
Perform a wiggle test on wiring while monitoring live data (if applicable).
Use a multimeter to check sensor/actuator resistance, voltage, and ground integrity.
Compare live data readings to factory specifications.
If circuit-related, trace the wiring diagram and test for opens, shorts, or high resistance.
Clear the code and perform a road test to verify repair.

Recommended Repairs

Replace or repair the faulty Crankshaft Position Sensor if testing confirms failure.
Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean components (throttle body, MAF sensor, EGR valve) if contamination is present.
Update ECM/TCM software if a technical service bulletin (TSB) applies.
Replace related fluids (transmission fluid, coolant) if degraded or incorrect.
Verify repair by clearing codes and completing an extended road test under various conditions.
