DTC P0010: “A” Camshaft Position Actuator CircuitS7RS0B1104013
System and Wiring DiagramStep Action Yes No
1 DTC check
1) Start engine and recheck DTC of ECM and TCM (for A/T
model) while engine running.
Is there any DTC(s)? Go to Step 2 of “Engine
and Emission Control
System Check”, Step 2
of “A/T System Check in
Section 5A”.Go to Step 2.
2 CAN communication line circuit check
1) Check CAN communication line circuit between
combination meter and ECM, TCM (for A/T model)
referring to Step 3 of “DTC P1674: CAN Communication
(Bus Off Error)”.
Is circuit in good condition? Substitute a known-
good combination meter
and recheck. If MIL still
remains OFF, substitute
a known-good ECM and
recheck.
Repair or replace CAN
communication circuit.

Circuit Description
Actual valve timing fails to become close to target advance level of each function although advance control function or
retarded advance control function is at work.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure 1) Clear DTC. Refer to “DTC Clearance”.
2) Start engine and keep it at idle for 10 seconds.
3) Check DTC. Refer to “DTC Check”.
DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/ or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
