P0332 on Kia
Knock Sensor 2 Circuit Low Input (Bank 2)
P0332 on Kia vehicles indicates knock sensor 2 circuit low input (bank 2). Au7o has documented this code across 1 Kia model — most commonly on Sorento. 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.
Common Causes of P0332
- •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
P0332 on Kia by Model
Kia Sorento(1 issue)
- Theta II Engine Bearing Failure and Seizure2011-2019
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.

What does P0332 mean on 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 specifically, this code is documented across 1 model.
What causes P0332 on Kia vehicles?▼
Common causes on Kia: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0332 on a Kia?▼
Repair costs vary widely depending on the root cause and specific Kia model.
