Engine Control System (4HK1) 1A-65
DTC P0016 (Flash Code 16)
Circuit Description
The crankshaft position (CKP) sensor is located on the
flywheel housing. The sensor rotor is fixed on the
flywheel. There are 56 notches spaced 6° apart and a
30° section that is open span. This open span portion
allows for the detection of top dead center (TDC).
The camshaft position (CMP) sensor is installed on the
cylinder head at the rear of the camshaft gear. The
CMP sensor detects total of five holes per one engine
cycle (four holes arranged equally every 90° and one
reference hole on the camshaft gear surface).
Detecting the open span portion from the CKP sensor
and one reference hole from the CMP sensor, the ECM
determines cylinder #1 compression TDC to ensure
they correlate with each other. If the ECM detects both
signals are out of synchronization, this DTC will set.
Condition for Running the DTC
• DTCs P0335, P0336, P0340 and P0341 are not
set.
• The ignition switch is ON.
• The CKP sensor signal pulse is detected.
• The CMP sensor signal pulse is detected.
Condition for Setting the DTC
• The ECM detects that the CKP sensor signals and
CMP sensor signals are out of synchronization
during engine rotations.
Action Taken When the DTC Sets
• The ECM illuminates the MIL when the diagnostic
runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
Condition for Clearing the DTC
• Refer to DTC Type Definitions for Condition for
Clearing the MIL/ DTC - Type A.
Diagnostic Aids
• This DTC is cause by an incorrect mechanical
timing condition, which is most likely caused by
wrong installation of timing gear, flywheel or
camshaft.

1. Install a scan tool.
2. Turn OFF the ignition for 30 seconds.
3. Start the engine. If the engine does not start,
crank over the engine for 10 seconds.
4. Monitor the DTC Information with a scan tool.
Is DTC P0335, P0336, P0340 or P0341 also
set?
