P3334 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 P3334?

Short trips may be possible, but prolonged driving with P3334 active is not advised until the root cause is identified and repaired.

Will P3334 clear itself?

P3334 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.

P3334 - Crankshaft Position Sensor Circuit Intermittent

P3334 is a Diagnostic Trouble Code (DTC) indicating a fault related to Crankshaft Position Intermittent. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles. When P3334 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 Intermittent circuit or system.

What is P3334?

P3334 is a Diagnostic Trouble Code (DTC) indicating a fault related to Crankshaft Position Intermittent. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles.

When P3334 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 Intermittent 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 Intermittent 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 Intermittent 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.
