2012 subaru impreza p0841 This Service Information bulletin provides a new flow chart and additional diagnostic tools to assist Technicians with troubleshooting DTC P0841- SECONDARY OIL PRESSURE SENSOR PERFORMANCE. DTC DETECTING CONDITION: • Control valve hydraulic circuit malfunction • Secondary pressure sensor fault or characteristics malfunction. From the Subaru FSM: J: DTC P0841 SECONDARY OIL PRESSURE SENSOR PERFORMANCE. While your Subaru Impreza’s check engine light will come on, this particular code indicates that there’s something wrong with the transmission, specifically the transmission fluid pressure sensor circuit. Dealer says need a new transmission. The sensor should be tested, transmission fluid leaks should also be addressed, along with any damaged wiring or connectors on the transmission wiring harness. Hi folks my name is Robert and I got the code P0841 SECONDARY PRESSURE FAILURE on my transmission and have other dash lights on. You would have been better off with a VB from Subaru, but you may have gotten a good one from eBay. Transmission fluid is one of the most common causes of a P0841 OBDII code, so the level and condition should be assessed.
