DTC P0335-1F: Crankshaft Position Sensor "A" Circuit Intermittent; DTC P0335-2A: Crankshaft Position Sensor "A" Signal Stuck in Range; DTC P0335-31: Crankshaft Position Sensor "A" No Signal [12/2021 - ]: Procedure

Pre-procedure1

1. Start the engine.

   Procedure1

2. Read the values displayed on the GTS while the engine is running.

   Powertrain > Engine > Data List 

   Tester Display
   Engine Speed

   Standard

   Correct values are displayed.

   HINT: 

   • To check the engine speed change, display the graph on the GTS.
   • If the engine does not start, check the engine speed while cranking.
   • If the engine speed indicated on the GTS remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.
