About P1110

P1110 is a manufacturer-specific powertrain diagnostic trouble code recorded for Infiniti 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.

P1110 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 Infiniti code indicates a problem with the intake valve timing control system on the left bank (LH) of the engine. The system varies intake camshaft position by using an oil control solenoid to feed engine oil into a camshaft phaser, advancing or retarding the cam so the ECM can optimise torque, economy, and emissions across the rev range. The Engine Control Module (ECM) compares the actual intake camshaft angle against the commanded position, and sets this code when the system cannot achieve or hold the target timing because of a hydraulic, electrical, or mechanical fault. Drivers may no...
