P1145 — Right side Camshaft position actuator or sensor fault

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

About P1145

P1145 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 P1145 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

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.

P1145 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 varies intake camshaft timing using a camshaft mounted actuator, and the ECM confirms the result through the camshaft position signal, comparing actual cam phase against the crankshaft reference. DTC P1145 on these Nissan engines indicates a right side intake valve timing control position fault, meaning the camshaft position actuator or its feedback on the right bank is not performing as expected. The ECM may see the cam timing failing to reach the commanded position, or an implausible camshaft position signal relative to the crankshaft. Because the actua...
