39180-2B000 vs. 39265-2U100: Which Crankshaft Sensor Do You Need?

You have diagnosed the P0335 code. You know you need a new Crankshaft Position Sensor for your Hyundai or Kia.
But when you search online, you see two part numbers that look almost identical: 39180-2B000 and 39265-2U100.

Buying the wrong one means the connector won't fit, or worse, the bolt hole won't line up.
At Automotive-leader, we want you to get the right part the first time. Here is the definitive guide to telling them apart.

1. The Visual Difference (Check Your Old Part!)

The easiest way to know which one you need is to pull out your old sensor and look at two things: The Mounting Hole and The Connector.

• 39180-2B000:

  • Often has a slightly longer cable.

  • The connector shape is specific to older Gamma engines.

• 39265-2U100:

  • Often has a shorter, stubbier body.

  • Used on newer 1.4L and 1.6L engines (i30, Ceed, Accent).

(Pro Tip: Take a picture of your old sensor's plug before ordering!)

2. Engine Compatibility Guide

While you should always check your VIN, here is a general rule of thumb for these sensors:

Part # 39180-2B000 typically fits:

• Older Hyundai Elantra (2011-2015)

• Hyundai Soul (2010-2011)

• Engines: 1.6L Gamma (Older Gen)

3. Can I Use Them Interchangeably?

No.
Even if you manage to plug them in, the internal resistance and signal frequency sent to the ECU might be different. Using the wrong sensor will result in a continued No Start condition or a P0335 code that won't go away.
