DTC Confirmation Procedure
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 at engine start: less than 30 °C (86 °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, clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature. (ECT approx. 90 – 95 °C, 194 – 203 °F)
4) Run engine at idle speed for 10 min. or more.9MAP sensor output signal check
1) Check MAP sensor according to “Manifold Absolute
Pressure (MAP) Sensor Inspection (If Equipped) in
Section 1C”.
Is it in good condition?Substitute a known-
good ECM and recheck.Faulty MAP sensor. Step Action Yes No

DTC P0340: Camshaft Position (CMP) Sensor CircuitS6RW0D1104042
Wiring Diagram5Ground circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between “BLK/ORN” wire terminal
of CKP sensor connector and engine ground.
Is measured resistance value less than 3
Ω?Go to Step 6. “BLK/ORN” wire is open
or high resistance.
6Was terminal “B+” voltage in Step 3 within specification?Go to Step 7. “BLK/RED” wire is open
circuit. If wire and
connection are OK,
substitute a known-
good ECM and recheck.
7Engine start signal check
1) Check starting motor circuit for opening and short
referring to Step 2 of “DTC P0616: Starter Relay Circuit
Low” and Step 3 and 4 of “DTC P0617: Starter Relay
Circuit High”.
Is check result satisfactory?Go to Step 8. Repair or replace.
8CKP sensor check
1) Check CKP sensor and sensor plate tooth referring to
“Camshaft Position (CMP) Sensor Inspection in Section
1C”.
Is check result satisfactory?Substitute a known-
good ECM and recheck.Replace CKP sensor
and/or sensor plate. Step Action Yes No

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.

1) With ignition switch turned OFF, connect scan tool to DLC.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Drive vehicle in 2000 – 3500 rpm of engine speed.
5) Keep above vehicle speed for 1 min. (Throttle valve opening is kept constant in this step.)
6) Stop vehicle and check DTC and pending DTC.
