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
