Trouble diagnosis name
DTC detecting condition
Possible cause
P0335
Crankshaft position sen-
sor (POS) circuit
• The crankshaft position sensor (POS) signal
is not detected by the ECM during the first
few seconds of engine cranking.
• The proper pulse signal from the crankshaft
position sensor (POS) is not sent to ECM
while the engine is running.
• The crankshaft position sensor (POS) signal
is not in the normal pattern during engine run-
ning.
• Harness or connectors
[CKP sensor (POS) circuit is open or
shorted.]
(APP sensor 2 circuit is shorted.)
(EVAP control system pressure sensor
circuit is shorted.)
(Refrigerant pressure sensor circuit is
shorted.)
• Crankshaft position sensor (POS)
• Accelerator pedal position sensor
• EVAP control system pressure sensor
• Refrigerant pressure sensor
• Signal plate
