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
