The APDTY 139213 Crankshaft Position Sensor is a direct-replacement CKP sensor designed for select Hyundai and Kia models equipped with L4 (4-cylinder) engines. This sensor monitors crankshaft rotation and sends critical timing signals to the engine control module (ECM), enabling proper fuel injection and ignition timing. When a crankshaft position sensor fails, symptoms include no-start conditions, intermittent stalling, rough idle, hesitation, and engine misfires. Part number 139213 replaces OE number 39180-2B000 and multiple aftermarket equivalents.

What Does the Crankshaft Position Sensor Do?
The crankshaft position sensor (CKP) is a magnetic or Hall-effect sensor that monitors the position and rotational speed of the crankshaft. Mounted near the crankshaft pulley, harmonic balancer, or flywheel, it generates a signal each time the crankshaft rotates. The engine control module (ECM) uses this real-time data to:
- Calculate precise ignition timing for each cylinder
- Control fuel injector pulse width and timing
- Monitor engine RPM
- Detect misfires and crankshaft position anomalies
Without an accurate CKP signal, the ECM cannot determine when to fire spark plugs or open fuel injectors, resulting in a no-start condition or severe driveability issues. The APDTY 139213 sensor restores this critical engine timing function in compatible Hyundai and Kia vehicles.
What Are the Symptoms of a Failing Crankshaft Position Sensor?
A failing or faulty CKP sensor produces several recognizable symptoms that worsen over time:
- No-start or hard-start condition: Engine cranks but does not fire, or requires extended cranking
- Intermittent stalling: Engine shuts off unexpectedly while driving, then may restart after cooling
- Rough idle and hesitation: Erratic idle speed, surging, or stumbling during acceleration
- Engine misfires: Random or cylinder-specific misfire codes (P0300-P0304)
- Check engine light: Common codes include P0335 (Crankshaft Position Sensor A Circuit), P0336 (Crankshaft Position Sensor A Circuit Range/Performance), P0339 (Crankshaft Position Sensor A Circuit Intermittent)
- Tachometer fluctuation or dropout: RPM gauge behaves erratically or drops to zero while engine runs
Heat cycling and vibration commonly cause internal sensor failure, particularly as mileage increases. Replacing the sensor at the first sign of these symptoms prevents roadside breakdowns.
Which Vehicles Does APDTY 139213 Fit?
APDTY 139213 is engineered for select Hyundai and Kia models equipped with L4 (4-cylinder) engines. The product data also indicates compatibility with certain Dodge models. Because crankshaft position sensor design varies by engine family and model year, you must verify fitment using the live compatibility chart on the product page before ordering.
Do not rely solely on make, model, or year—engine configuration, VIN range, and production date may affect sensor design. The compatibility chart cross-references your specific vehicle details to ensure correct fitment of part number 139213.
If you are unsure whether this sensor fits your vehicle, consult the online chart or contact APDTY customer support with your VIN.

How to Install a Crankshaft Position Sensor (General Overview)
Crankshaft position sensor replacement is straightforward on most vehicles and requires basic hand tools. Follow these general steps:
- Disconnect the battery: Remove the negative terminal to prevent electrical shorts or accidental starter engagement.
- Locate the sensor: On L4 engines, the CKP sensor is typically mounted near the crankshaft pulley, harmonic balancer, or transmission bell housing. Consult a service manual for exact location on your vehicle.
- Disconnect the wiring harness: Press the release tab and unplug the electrical connector from the sensor.
- Remove the mounting bolt: Use a socket or wrench to remove the single bolt securing the sensor to the engine block or timing cover.
- Extract the old sensor: Gently pull the sensor from its mounting bore. Some resistance is normal; do not pry or twist.
- Inspect the mounting area: Clean any dirt, oil, or debris from the sensor bore and surrounding surfaces.
- Install the new sensor: Insert APDTY 139213 into the mounting bore, ensuring the O-ring (if equipped) seats properly. Torque the mounting bolt to manufacturer specification (typically 5–10 ft-lbs).
- Reconnect the wiring harness: Push the connector onto the sensor until it clicks into place.
- Reconnect the battery: Reattach the negative terminal and tighten the clamp.
- Clear codes and test: Use an OBD-II scanner to clear stored fault codes, then start the engine and verify smooth operation. Road-test the vehicle and confirm no warning lights return.
Safety Note: Work only on a cool engine to avoid burns. Ensure the vehicle is in Park (automatic) or Neutral (manual) with the parking brake engaged. If your vehicle has been towed or cranked repeatedly without starting, allow the starter motor to cool before further testing.
Frequently asked questions
Will APDTY 139213 fit my Hyundai or Kia?
APDTY 139213 is designed for select Hyundai and Kia models with L4 engines, as well as certain Dodge models. You must check the live compatibility chart on the product page to verify fitment for your specific vehicle year, make, model, and engine. Do not assume fitment based on make or year alone.
What OE part number does APDTY 139213 replace?
APDTY 139213 directly replaces OE part number 39180-2B000 (391802B000). It also cross-references to aftermarket numbers PC934, PC934T, 907-787, 180-0735, 907787, 22A1244, 1KR310, and S10362.
Can a bad crankshaft position sensor cause a no-start condition?
Yes. A failed CKP sensor prevents the ECM from determining crankshaft position and timing, so the engine will crank but not start. Replacing the sensor typically restores normal starting and operation immediately.
Do I need to clear codes after installing the new sensor?
Yes, use an OBD-II scanner to clear stored fault codes after installation. This ensures the check engine light does not remain illuminated due to old data and allows you to confirm the repair resolved the issue.
The APDTY 139213 Crankshaft Position Sensor restores critical engine timing signals in select Hyundai, Kia, and Dodge L4 engines, eliminating no-start conditions, stalling, misfires, and rough idle.
