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.
