P0332 on Kia: How to Diagnose & Fix
Knock Sensor 2 Circuit Low Input (Bank 2)

P0332 on Kia by model: symptoms, diagnosis and fix
The Theta II 2.4L and 2.0T GDI engines in 2011-2019 Sorentos can experience catastrophic engine seizure due to machining debris left in the crankshaft oil passages during manufacturing. Metal shavings restrict oil flow to rod and main bearings, causing premature bearing wear and eventual engine lock-up. Over 340,000 Sorentos were included in NHTSA Recall 17V-224. Kia extended the powertrain warranty to 10 years/120,000 miles for affected vehicles and deployed the Knock Sensor Detection System (KSDS) software update to detect early bearing deterioration.
Common Symptoms
- Engine knocking or ticking noise that worsens over time
- Oil pressure warning light illuminated
- Metal shavings found in oil during changes
- Sudden engine stall while driving
- Excessive oil consumption (more than 1 qt per 1,000 miles)
- Check engine light with bearing-related codes
How to Fix
Check VIN eligibility for extended warranty (10 years/120,000 miles). Have dealer perform KSDS software update to detect early bearing failure. If engine is knocking, dealer will perform oil consumption test and bearing inspection. Complete engine replacement required if bearings are scored. Dealer replaces with updated long block assembly under warranty if eligible.

Owner tips & cautions
- WarningIf you hear any knocking, stop driving immediately. Continued operation with failing bearings causes catastrophic damage that may not be covered if engine locks up completely
- TipCheck your VIN at owners.kia.com/recalls - even if past the original warranty, the extended 10yr/120k warranty applies to Theta II bearing failures
- TipUse 0W-20 full synthetic oil and change every 5,000 miles to maximize bearing life. Pennzoil Platinum or Mobil 1 are frequently recommended on KiaForums

Frequently asked questions
What does P0332 mean on a Kia?
P0332 stands for "Knock Sensor 2 Circuit Low Input (Bank 2)." This code means the Engine Control Module detected a low-voltage (or low-amplitude) signal from Knock Sensor 2 on Bank 2 — the cylinder bank that does not contain cylinder 1. The knock sensor 'listens' for engine detonation (pinging) so the computer can retard ignition timing to protect the engine. P0332 sets when this sensor's signal is consistently lower than expected, suggesting the sensor, its wiring, or connection is faulty. To stay safe, the ECM may pull timing, which can slightly reduce power and fuel economy. On Kia it is documented across 1 model: Sorento.
What are the most common causes of P0332?
The most common causes of P0332 are: Faulty knock sensor on Bank 2, Open or high-resistance wiring in the knock sensor circuit, Corroded or loose knock sensor connector, Poor ground for the knock sensor, Chafed or shorted sensor harness, Improper sensor torque/mounting (poor contact with the block), Faulty ECM/PCM knock sensor input. The specific cause varies by vehicle.
How much does it cost to fix P0332 on a Kia?
Repair costs vary widely with the root cause and Kia model; each issue on this page carries its own estimate where one is published.
