Code Definition

P1335 — Crankshaft Position Sensor (REF)

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

About P1335

P1335 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.

When P1335 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.

P1335 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

Nissan and Infiniti engines that use this code are fitted with two separate crankshaft signals, the position signal known as POS and the reference signal known as REF. DTC P1335 relates to the crankshaft position sensor REF circuit, where the REF sensor is mounted at the crankshaft pulley and provides the Engine Control Module (ECM) with a 120 degree reference used to identify cylinder position for sequential fuel injection and ignition timing. The code sets when the ECM does not receive a valid REF signal, or the signal is intermittent or out of correlation with the camshaft and POS signals. ...
