Code P0327 2010 Nissan Pathfinder Description
The P0327 diagnostic trouble code (DTC) for a 2010 Nissan Pathfinder indicates a Knock Sensor Circuit Low Input Bank 1 error. The knock sensor is a crucial component in the engine management system that detects abnormal combustion noises, known as engine knock or detonation. When the knock sensor detects these noises, it sends a signal to the engine control module (ECM) to adjust the ignition timing and prevent engine damage.
Common Causes of P0327 2010 Nissan Pathfinder
- Faulty knock sensor
- Damaged wiring or connectors
- Engine mechanical issues causing abnormal combustion
- ECM software or hardware problems
- Corrosion or contamination in sensor connections
Symptoms of P0327 2010 Nissan Pathfinder
- Reduced engine power
- Poor acceleration
- Rough idling
- Engine misfires
- Illuminated check engine light
How to Fix P0327 2010 Nissan Pathfinder
- Begin by diagnosing the knock sensor circuit using a scan tool to confirm the P0327 code and check for any related codes.
- Inspect the knock sensor, wiring, and connectors for any visible damage or corrosion. Replace any faulty components.
- Test the knock sensor using a multimeter to ensure it is functioning correctly.
- Clear the DTC and reset the ECM to see if the code returns after repairs.
- Test drive the vehicle to confirm that the symptoms associated with the code have been resolved.
Cost to Fix P0327 2010 Nissan Pathfinder
The typical repair costs for addressing a P0327 code on a 2010 Nissan Pathfinder can range from $150 to $400, including parts and labor.

Frequently Asked Questions about P0327 2010 Nissan Pathfinder Code
1. What does the OBDII code P0327 mean on a 2010 Nissan Pathfinder?
P0327 indicates the Knock Sensor Circuit Low Input on Bank 1, meaning the engine control module (ECM) is detecting an unusually low voltage signal from the knock sensor.
2. What are the symptoms of a P0327 code on a 2010 Nissan Pathfinder?
Common symptoms include reduced engine performance, poor fuel efficiency, engine knocking or pinging, and possibly an illuminated check engine light.
3. What causes the P0327 code in a 2010 Nissan Pathfinder?
Common causes include a faulty knock sensor, damaged knock sensor wiring or connectors, excessive engine vibrations, or issues with the ECM.
4. Can I still drive my 2010 Nissan Pathfinder with a P0327 code?
While the vehicle may still operate, driving with this code can lead to engine damage due to improper ignition timing and knocking. It’s best to address the issue promptly.
5. How do I diagnose a P0327 code in my 2010 Nissan Pathfinder?
Diagnosis involves inspecting the knock sensor and its wiring for damage, checking the sensor’s resistance with a multimeter, and testing for proper voltage at the sensor connector.
6. Where is the knock sensor located on a 2010 Nissan Pathfinder?
The knock sensor is typically located on the engine block, cylinder head, or intake manifold, close to Bank 1 (the side of the engine with cylinder 1).
7. How much does it cost to fix a P0327 code on a 2010 Nissan Pathfinder?
Repair costs vary but typically range from $150 to $400, depending on whether it’s just the sensor or if wiring and labor add to the expense.
8. Can a bad knock sensor damage my engine?
Yes, a failing knock sensor can prevent the ECM from detecting engine knocking, leading to potential engine damage over time if not repaired.
9. What tools are needed to fix a P0327 code on a 2010 Nissan Pathfinder?
You’ll need a multimeter, OBDII scanner, basic hand tools, and potentially a replacement knock sensor to diagnose and repair the issue.
