What P0335 means
"Crankshaft position sensor A circuit" names the circuit of the sensor that tells the computer where the crankshaft is and how fast it is turning, with A marking the first such sensor. The name identifies the circuit, not a reading: the engine speed figure derived from that sensor is a separate thing the computer publishes.
This is a standard code. It means the same thing on every make of vehicle.
What the program shows for P0335
Engine speed is the reading the computer derives from that sensor, live on the Dashboard as a trace over a dial spanning 0 to 7,000 rpm, with its own warm-idle band applied only while the engine is idling. The freeze frame tab shows the engine speed the car stored at the moment it set the code.
The Dashboard's Misfire count cards show one counter per cylinder once the engine is running, next to the Engine speed and Ignition timing traces. The Full scan's On-board self-tests give each cylinder's misfire count for the last ten drives and this drive with its share of the total, and a recorded drive works out a misfire rate over that recording for the Analysis screen and the printed report. The Inspection screen shows whether the Misfire detection monitor is done or still running.
