About P1130

P1130 is a manufacturer-specific powertrain diagnostic trouble code recorded for Nissan vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1130 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The swirl control valve system uses butterfly valves in each intake port that close at idle and low engine speed to increase intake air velocity, improving fuel vaporisation and creating a swirl in the combustion chamber for better low speed combustion. The swirl control valve control solenoid valve, operated by the Engine Control Module (ECM), switches intake manifold vacuum to the swirl control valve actuator, when the ECM grounds the solenoid it applies vacuum to close the valves, and when it cuts the signal the valves open. DTC P1130 is set when the ECM detects an improper electrical signa...
