CONSULT screen terms

(Trouble diagnosis content)

DTC detecting condition

P0335

CKP SEN/CIRCUIT
(Crankshaft position sensor “A” 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.

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Device fix mode

• This mode fixes the IVT control solenoid valve and the EVT control solenoid valve in the refer-

ence position.

• The intake manifold runner control valve motor is turned OFF (intake manifold runner control

valve opens).
