Code P1327 Description
The P1327 code indicates that there is a low input signal from the knock sensor 2 in the vehicle's engine. The knock sensor is responsible for detecting abnormal combustion in the engine, such as knocking or pinging, and sending signals to the engine control module (ECM) to adjust the ignition timing for optimal performance. A low input from the knock sensor can result in decreased engine performance, reduced fuel efficiency, and potential engine damage if left unaddressed.
Common Causes of P1327
- Faulty knock sensor
- Wiring or connector issues in the knock sensor circuit
- Engine mechanical problems causing abnormal combustion
- ECM software or hardware issues
- Engine overheating
Symptoms of P1327
- Engine knocking or pinging noises
- Decreased engine power or acceleration
- Poor fuel economy
- Illuminated check engine light
- Engine misfires
How to Fix P1327
- Diagnose the issue by using a scan tool to identify the specific knock sensor 2 low input code.
- Inspect the knock sensor wiring and connector for any damage or corrosion. Repair or replace as needed.
- Test the knock sensor to ensure it is functioning properly. Replace the sensor if necessary.
- Check for any engine mechanical issues that could be causing abnormal combustion. Repair as needed.
- Clear the trouble code from the ECM and perform a test drive to verify that the issue has been resolved.
Cost to Fix P1327
The cost of repairing a knock sensor 2 low input code can vary depending on the make and model of the vehicle, the location of the repair shop, and the extent of the issue. On average, the cost of replacing a knock sensor and addressing related wiring or connector issues can range from $200 to $500, including parts and labor.
