Crankshaft Position/Top Dead Genter/Gylinder Position (CKP/TDC/CYPI Sensor
The scan tool indicates Diagnostic Trouble Code (DTC) P0335; A malfunction in the Crankshaft Position (CKP)
sensor circuit,
The scan tool indicates Diagnostic Trouble Code (DTC) P0336: A range/performance problem in the Crankshaft
Position {CKP) sensor circuit.
The scan tool indicates Diagnostic Trouble Code {DTC) P1361: Intermittent interruption in the Top Dead Center

(CYP) sensor circuit.
The scan toot indicates Diagnostic Trouble Code {DTC) P1382: No signal in the Cylinder Position (CYP} sensor
circuit.
Description
The CKP Sensor determines timing for fuel injection and ignition of each cylinder and also detects engine speed. The TDC
Sensor determines ignition timing at start-up {cranking) and when crank angle is abnormal. The CYP Sensor detects the
position of No. 't cylinder for sequential fuel injection to each cylinder. The CKP/TDC/CYP Sensor is built into the distribu-
ror.
NOTE: lf DTC P1359 is stored atthesametimeas DTC P0335, P0336, Pl361, P1362, P1381 and/or P1382, troubleshoot DTC

Description
The diagnostic system has a pulser rotor on the crankshaft and a pulse pick-up sensor on the engine block. The ECM/PCM
monitors the crankshaft speed fluctuation based on the CKF sensor signal, and judges that an engine misfire occurred if
