P1135 — Intake Valve Timing Control, LH Bank 2

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

About P1135

P1135 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 P1135 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.

P1135 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 intake valve timing control system, known as VTC on Nissan engines, varies the intake camshaft timing to optimise power, economy and emissions across the operating range. The Engine Control Module (ECM) commands an intake valve timing control solenoid valve that directs engine oil pressure to the camshaft phaser, advancing or retarding the intake cam. DTC P1135 is set when the ECM detects that the intake valve timing control on bank 2 is not responding correctly, meaning the measured cam phase does not follow the commanded position, or the solenoid circuit is faulty. Because the solenoid r...
