DTC P0335: Crankshaft Position Sensor Circuit Malfunction

CIRCUIT OPERATION
• The crankshaft position sensor power is supplied from the MFI relay (terminal 1), and the ground is provided on the vehicle body.
• A 5-volt voltage is applied on the crankshaft position sensor output terminal (terminal 2) from the PCM (terminal 45). The crankshaft position sensor generates a pulse signal when the output terminal is opened and grounded.
TECHNICAL DESCRIPTION
• The crankshaft position sensor detects the crank angle (position) of each cylinder, and converts that data to pulse signals, which are then input to the PCM.
• When the engine is running, the crankshaft position sensor outputs a pulse signal.
• The PCM checks whether pulse signal is input while the engine is cranking.
DTC SET CONDITIONS

Check Conditions
Engine is being cranked.

Judgment Criteria
• Crankshaft position sensor output voltage has not changed (no pulse signal is input) for 2 seconds.

Check Conditions, Judgment Criteria
• Normal signal pattern has not been input for cylinder identification from the crankshaft position sensor signal and camshaft position sensor signal for 2 seconds.
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: )
• Crankshaft position sensor failed.
• Open or shorted crankshaft position sensor circuit, or loose connector.
• PCM failed.
