Model: Nissan Pathfinder 2004 Platinum Fault Code: P0174 Posted: 2016-03-15 07:07

Good afternoon, fellow car enthusiasts. I'm currently dealing with two diagnostic error codes on my 2004 Nissan Pathfinder Platinum model: P0174 and P1130. The P0174 code indicates a system lean condition in the fuel mixture of cylinder 4, while P1131 points to an issue with the swirl control valve. I'm seeking advice on how to diagnose and resolve these issues effectively. Any insights or troubleshooting steps would be greatly appreciated.

P0174: System too lean - indicates an imbalance in the air-fuel mixture, possibly due to a vacuum leak or faulty oxygen sensor. P1131: Swirl control valve malfunction - check the swirl control valve solenoid for vacuum leaks and ensure proper operation. A failing valve can cause poor engine performance and increased emissions.
