DTC P0335-00: Crank Angle Sensor system
 
 
 
 
CIRCUIT OPERATION
  • Output signal is supplied to the ECM connector terminal number 35 from the crankshaft position sensor connector terminal number 3 and is grounded to the ECM connector terminal number 34 from the crankshaft position sensor connector terminal number 2.
  • A power voltage of 5 volts is applied to the crankshaft position sensor connector terminal number 1 from the ECM connector terminal number 24.
 
 
TECHNICAL DESCRIPTION
  • The crankshaft position sensor detects the crank angle (position) of each cylinder, and converts that data to pulse signals, then which are input to the ECM.
  • When the engine is running, the crankshaft position sensor outputs a pulse signal.
  • The ECM checks whether pulse signal is input while the engine is cranking.
 
 
DESCRIPTIONS OF MONITOR METHODS
  • Crankshaft position sensor signal does not change.
  • Crankshaft position sensor signal is not normal pattern.
 
 
MONITOR EXECUTION
Continuous.
