Is Your Kia Sportage Stalling or Hard to Start?
A failing crankshaft position sensor is a common issue on the 2012-2017 Kia Sportage with either the 2.0L or 2.4L engine. This small sensor plays a huge role in how your engine runs. When it starts to fail, it can cause a range of frustrating problems, from poor performance to leaving you stranded. Because it can cause the engine to stall unexpectedly, it is a serious safety concern.
Check Engine Light and P0335 Code
The most common sign of a bad crankshaft sensor is the check engine light illuminating on your dashboard. If you use an OBD-II scanner, you will likely find the code P0335: Crankshaft Position Sensor 'A' Circuit Malfunction. This code specifically points to a problem with the sensor or its wiring.
Symptoms of a Failing Crankshaft Sensor
- Engine Won't Start: The engine cranks but never turns over.
- Intermittent Stalling: The engine shuts off randomly while driving, often at low speeds or when stopping. This is a critical safety issue.
- Rough Idle and Misfires: The engine may shake or run unevenly when stopped.
- Poor Acceleration: The car feels sluggish and lacks power when you press the gas pedal.
- Reduced Fuel Economy: A bad sensor disrupts engine timing, leading to inefficient fuel combustion and more trips to the gas station. 🎬 Watch: A breakdown of common bad crankshaft sensor symptoms
Choosing the Right Aftermarket Sensor: Brand Quality Matters
When replacing this sensor, quality is key. A cheap, poorly made sensor can fail quickly or provide inaccurate readings, leading you right back to where you started. It's often worth paying a little more for a reputable brand to avoid the headache of a repeat repair.
- Premium Brands (OEM Quality): Mando is the Original Equipment (OE) supplier for Kia, so it's a direct replacement for the factory part. NGK/NTK and Delphi are also considered top-tier OE-level suppliers known for their quality and reliability in sensors.
- Trusted Aftermarket Brands: Brands like Standard Motor Products (SMP), Beck Arnley, and Holstein offer a good balance of quality and value. They are generally reliable, but be aware that some brands, like SMP, have different quality tiers.
- Value-Oriented Brands: Dorman is a popular choice that offers a cost-effective, direct-fit replacement. While many users have success with these parts, the consensus among mechanics is to stick with premium or trusted brands for critical sensors.
