System Description
The CMP sensor located on the transmission side of cylinder head (VVT model) or timing chain cover (non-VVT
model) consists of the signal generator (magnetic sensor) and signal rotor (intake camshaft portion (VVT model) or
exhaust camshaft timing sprocket (non-VVT model)).
The signal generator generates reference signal through slits in the slit plate which turns together with the camshaft.
Reference signal
The CMP sensor generates 6 pulses of signals each of which has a different waveform length while the camshaft
makes one full rotation. Refer to “Inspection of ECM and Its Circuits”.
Based on these signals, ECM judges which cylinder piston is in the compression stroke and the engine speed.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Crank engine for 5 sec.
4) Check DTC and pending DTC.
DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
“Precautions for DTC Troubleshooting”.

DTC detecting condition Trouble area
• CMP sensor pulse is less than 20 pulses per crankshaft 8 revolutions
or
• CMP sensor pulse is more than 28 pulses per crankshaft 8
revolutions
or
• CMP sensor pulse is less than 20 pulses between BTDC 75° CA and

Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2CMP sensor and connector for proper installation check

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out by 2 persons, a driver and a tester, on a level road.

NOTE
Check to make sure that following conditions are satisfied when using this “DTC confirmation
procedure”.
• Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine coolant temperature: 70 °C (158 °F) or more
• Altitude (barometric pressure): 2500 m, 8200 ft or less (560 mmHg, 74.4 kPa or more)

1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature.
4) Run engine at idle for 10 min.
5) Drive vehicle and increase engine speed 3000 rpm in 3rd gear or “3” range.
6) Release accelerator pedal and with engine brake applied, keep vehicle coasting for 5 sec. or more. (Keep fuel cut
condition for 5 sec. or more) If fuel cut condition is not kept for 5 sec. or more, coast down a slope in engine speed
1000 – 3000 rpm for 5 sec. or more.
7) Stop vehicle and run engine at idle.
8) For european market model, check whether EGR system readiness/monitoring test has completed or not by using
scan tool.
If evaporative system readiness/monitoring test has not completed, check vehicle conditions (environmental) and
repeat Steps 3) through 7).
9) Check DTC and pending DTC.DTC detecting condition Trouble area
