Ignition Knock Sensor for Subaru and Nissan
Global Parts 1815050 is an ignition knock sensor that monitors engine vibration patterns and helps identify pre-ignition or detonation events. It is a direct-fit style emission control sensor for select Subaru, Nissan, and INFINITI applications, including Subaru BRZ, Crosstrek, Forester, Impreza, WRX, Legacy, and Outback models.
Key Features
- Part number 1815050 ignition knock (detonation) sensor
- Blade terminal type with 2 terminals
- 1 female oval connector
- Designed for engine block, cylinder head, or intake manifold mounting locations
- Fits select 2014-2025 Subaru, Nissan, and INFINITI applications
- This part cross-references Subaru 22060AA18A and ES113700 for the same application.
How It Works
The knock sensor detects abnormal engine vibrations caused by detonation or pre-ignition and sends that signal to the engine management system. On vehicles such as the Subaru Ascent, BRZ, Crosstrek, Forester, Impreza, WRX, Legacy, and Outback, as well as select Nissan and INFINITI models, accurate knock sensing helps the ECU respond to combustion irregularities and maintain proper engine operation.
Common Issues It May Address
- Knock sensor fault codes
- Engine pinging or detonation-related drivability concerns
- Rough running caused by incorrect knock signal input
- Reduced engine performance from sensor failure
- Check engine light related to the knock sensor circuit
Installation Notes
Verify connector shape, terminal count, and mounting location before installation. This sensor uses a female oval connector with blade terminals, so matching the electrical connection is important for proper fitment. Confirm vehicle application by year, make, and model before replacing the original sensor.
