P1111 — Intake valve timing control solenoid bank 1

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Nissan

About P1111

P1111 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.

When P1111 is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

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.

P1111 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

This Nissan code identifies a fault with the intake valve timing control solenoid on Bank 1. The solenoid is an electrically operated oil control valve that the Engine Control Module (ECM) pulses to feed oil into the intake camshaft phaser, advancing or retarding the cam to optimise performance, fuel efficiency, and emissions. The ECM sets this code when the solenoid or its circuit does not operate correctly, for example failing to advance or retard timing on command, or showing an electrical fault in the control circuit. Symptoms can include rough idle, hesitation, reduced power, a cam timing...
