Crankshaft Position/Top Dead Genter/Gylinder Position (CKP/TDC/CYP) Sensor
('96 - 98 Models, '!n - 00 D16Y5 engine with M/Tl
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 CrankshaftPosition (CKP) sensor circuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P1361: Intermittent interruotion in the Too Dead Center(TDC) sensor circuit.
The scan tool indicates Diagnostic Trouble Code {DTC) P1362: No signal in the Top Dead Center (TDC} sensorcircuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P1381: Intermittent interruption in the Cvlinder Position{CYP) sensor circuit.
The scan tool indicates Diagnostic Trouble Code {DTC) Pl382: No signal in the Cylinder Position (CYP} sensorcircuit.
Description
The CKP Sensor determines timing for fuel injection and ignition of each cylinder and also detects engine speed. The TDCSensor determines ignition timing at start-up (cranking) and when crank angle is abnormal. The Cyp Sensor detects theposition of No. 1 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 atthesametime as DTC P0335. P0336, P1361, Pl362, P1381 and/or P1382, troubteshoor DTCP1359 first, then recheck for those DTCS. Ot6y5 6ngine: Dt6y7, ot6y8 enqin6s:
