Detailed Description
Hitachi Astemo engineered the CPS0100 to meet the requirements of specific Subaru engine applications. As a camshaft position sensor, it monitors camshaft position and sends the data needed for accurate fuel and ignition control. This part cross-references Standard Ignition PC190 for the same application. The CPS0100 is used on select Subaru Legacy and Subaru Impreza applications across multiple model years, along with Subaru Outback, Forester, and Baja coverage. If you are replacing a failing Subaru camshaft position sensor, CPS0100 provides the OE-style fit and signal performance expected for these vehicles.
