P1335 — No Crankshaft Position Sensor Signal - Engine Running

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

About P1335

P1335 is a manufacturer-specific powertrain diagnostic trouble code recorded for Lexus 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

The crankshaft position sensor on this Lexus provides the Engine Control Module (ECM) with the primary engine speed and crankshaft position signal used for fuel injection and ignition timing. DTC P1335 sets when the ECM loses the crankshaft position sensor signal while the engine is running, having seen a valid signal during cranking. The sensor is typically a magnetic or hall effect type reading a toothed reluctor or timing rotor on the crankshaft. When this code is stored the engine may stall, cut out intermittently, run erratically, or fail to restart, since the ECM cannot maintain correct ...
