DTC P0016 Crankshaft Position - Camshaft Position Correlation (4JJ3 without DPD)

1. DTC P0016 description

The CKP sensor is installed to the left side of the rear of the cylinder block. The sensor rotor is fixed on the crankshaft. There are 56 notches spaced 6° apart and a 30° opening. Top dead center of cylinder No. 1 can be detected through this opening. The CMP sensor is installed on the timing chain sprocket cover at the front of the camshaft idle gear. The CMP sensor detects 5 protrusions in total per 1 engine cycle. The timing chain sprocket has 4 protrusions evenly spaced 90° apart and 1 reference protrusion. By detecting the opening with the CKP sensor and the 1 reference protrusion with the CMP sensor, the ECM determines compression top dead center of cylinder No. 1 to make sure they correlate with each other. If the ECM detects that both signals are not synchronized, the DTC is set.
