P1337 ACURA, HONDA: CRANKSHAFT POSITION SENSOR 2 NO SIGNAL
The CKP sensor (Crankshaft Position Sensor) is used by the engine to record the crankshaft rotational speed. This data is provided to the Engine Control Module (ECM), which uses it to determine when the spark will occur and in which cylinder. This information is also used to monitor cylinder misfires. On certain vehicle models, this sensor is installed near the crankshaft pulley. On the other hand, in other vehicles, it is also installed in the transmission bell housing or the engine cylinder block.
The way the crankshaft position sensor is placed allows the reluctor ring teeth joined to the crankshaft to be very near the tip of the sensor. Typically, this ring is missing one or more teeth so that the control module can be provided with the reference point to the crankshaft position. As the crankshaft rotates, the sensor produces a pulsed voltage signal. Each pulse corresponds to the ring tooth.
The P1337 OBDII diagnostic code setting for Acura and Honda manufacturers occurs when the signal expected from the Crankshaft Position Sensor 2 is not present or is deficient.
