P0327 2011 Toyota Camry Code - Knock Sensor 1 Circuit Low Input Bank 1
Quick Answer
Flat type knock sensors (non-resonant type) have structures that can detect vibrations over a wide band of frequencies: between approximately 6 kHz and 15 kHz. Common causes include Faulty knock sensor, Knock sensor circuit poor electrical connection, Knock sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0327 2011 Toyota Camry Description
A knock sensor is fitted onto the engine block to detect engine knocking. The knock sensor contains a piezoelectric element which generates a voltage when it becomes deformed. The voltage is generated when the engine block vibrates due to knocking. Any occurrence of engine knocking can be suppressed by delaying the ignition timing.
What are the Possible Causes of the DTC P0327 2011 Toyota Camry?
- Faulty knock sensor
- Knock sensor circuit poor electrical connection
- Knock sensor harness is open or shorted
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0327 2011 Toyota Camry?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

What does the OBDII code P0327 mean for a 2011 Toyota Camry?
P0327 indicates that the engine control module (ECM) has detected a low voltage signal from Knock Sensor 1 on Bank 1, which monitors engine vibrations for potential knocking or detonation.
What are the common symptoms of code P0327 in a 2011 Toyota Camry?
Symptoms may include a check engine light, reduced engine performance, poor fuel economy, engine knocking or pinging under load, and difficulty accelerating.
What causes the P0327 code to appear in a 2011 Toyota Camry?
Common causes include a faulty knock sensor, damaged or corroded wiring or connectors, a malfunctioning ECM, or engine mechanical issues such as carbon buildup or incorrect timing.
Can I drive my 2011 Toyota Camry with the P0327 code?
Driving with this code is not recommended as it can result in engine knocking or pinging, which may lead to long-term engine damage if the issue isn't addressed.
How do I diagnose the P0327 code in a 2011 Toyota Camry?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the knock sensor and its wiring, testing the sensor's resistance with a multimeter, and checking for any engine mechanical issues.
How do I fix the P0327 code in my 2011 Toyota Camry?
Repairs may include replacing the knock sensor, repairing or replacing damaged wiring, cleaning corroded connectors, updating or reprogramming the ECM, or addressing engine mechanical problems.
What is the knock sensor's role in a 2011 Toyota Camry?
The knock sensor detects engine vibrations caused by knocking or detonation and sends a signal to the ECM to adjust the ignition timing to prevent engine damage.
What tools are needed to troubleshoot the P0327 code?
Tools may include an OBDII scanner, a multimeter to test sensor resistance, basic hand tools to access the sensor, and possibly a service manual for wiring diagrams.
Where is Knock Sensor 1 located on a 2011 Toyota Camry?
Knock Sensor 1 is typically located on the engine block, cylinder head, or intake manifold, near Bank 1 (the side of the engine with cylinder 1).
How much does it cost to fix the P0327 code on a 2011 Toyota Camry?
Repair costs can vary, but replacing the knock sensor typically costs between $150 and $350 for parts and labor. Additional costs may arise if wiring repairs or further diagnostics are needed.
