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
{TDC) sensor circuit.
The scan tool indicates Diagnostic Trouble Code {DTC) P1362: No signal in the Top Dead Center (TDC) sensor
circuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P1381: Intermittent interruption in the Cylinder Position(CYP) sensor circuit.
lTiaSt The scan tool indicates Diagnostic Trouble Code (DTC) P1382; No signal in the Cylinder Position (CYP) sensor: circuil.
DoscriDtion
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. 1 cylinder for sequential fuel injection to each cylinder. The CKP/TDC/CYP Sensor is built into the distribu-
tor.
NOTE; lf DTC P1359 is stored at the same time as DTC P0335, P0336, P1361. P1362, P1381 and/or P1382, troubleshoot DTC
P1359 first, then recheck for those DTCS. D16Y5 engino:
