INSPECTION PROCEDURE
HINT:

Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records
the engine conditions when a malfunction is detected. When troubleshooting it is useful for determining
whether the vehicle was running or stopped. the engine was warmed up or not, the air-fuel ratio lean
or rich, etc. at the time of the malfunction.

READ VALUE OF HAND-HELD TESTER OR OBD II SCAN TOOL
(a) Connect the hand-held tester or the OBD II scan tool to the DLC3.
(b) Start the engine and push the hand-held tester or the OBD II scan tool main switch ON.
(c) Select the item ºDIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / ENGINE SPDº.

The engine speed can be confirmed in DATA LIST using the hand-held tester or OBD II scan tool. If
there is no NE signals from the crankshaft position sensor despite the engine revolving, the engine
speed will be indicated as zero. If voltage output of the crankshaft position sensor is insufficient, the
engine speed will be indicated as lower RPM (than the actual RPM).
1 Check resistance of crankshaft position sensor.
PREPARATION:
Disconnect the C3 crankshaft position sensor connector.
CHECK:
Measure the resistance between terminals 1 and 2.
OK:
Tester ConnectionSpecified Condition
12985 to 1,600 W at cold1 - 21,265 to 1,890 W at hot
NOTICE:
º Coldº and ºHotº shown above mean the temperature of
the coils themselves. ºColdº is form -10°C (14°F) to 50°C
(122°F) and ºHotº is from 50°C (122°F) to 100°C (212°F).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help deter-
mine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean
or rich, as well as other data from the time when a malfunction occurred.
1 Check resistance of camshaft position sensor.
PREPARATION:
Disconnect the C1 camshaft position sensor connector.
CHECK:
Measure the resistance between terminals 1 and 2.
OK:

9. DEFINITION OF TERMS
TermDefinition
Monitor descriptionDescription of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCsDiagnostic code
Typical enabling condition
Preconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the malfunction
threshold(s).
Sequence of operation
The priority order that is applied to monitoring, if multiple sensors and components are used to detect the malfunc-
tion.
When a sensor is being monitored, the next sensor or component will not be monitored until the sensor monitoring
is finished.
Required sensor/compo-
nentsThe sensors and components that are used by the ECM to detect malfunctions.
Frequency of operation
The number of times that the ECM checks for malfunctions per driving cycle.
ºOnce per driving cycleº means that the ECM detects the malfunction only one time during a single driving cycle.
ºContinuousº means that the ECM detects malfunction every time an enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a
DTC. This timing begins after the ºtypical enabling conditionsº are met.
Malfunction thresholdsBeyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operation
MIL illumination timing after a defect is detected.
ºImmediatelyº means that the ECM illuminates MIL the instant the ECM determines that there is a malfunction.
º2 driving cycleº means that the ECM illuminates MIL if the same malfunction is detected again in the 2nd driving
cycle.

(d) Using a pin hole grinder, hone the bushing to obtain the
standard specified clearance (See page EM-97) be-
tween the bushing and piston pin.
(e) Check the piston pin fit at normal room temperature. Coat
the piston pin with engine oil, and push it into the connect-
ing rod with your thumb.
3. REPLACE CRANKSHAFT FRONT OIL SEAL
HINT:
There are 2 methods ((a) and (b)) to replace the oil seal.
(a) If the oil pump is removed from the cylinder block:
(1) Using a screwdriver, pry out the oil seal.
(2) Using SST and a hammer, tap in a new oil seal until
its surface is flush with the oil pump body edge.
SST 09316-6001 1 (09316-00011)
(3) Apply MP grease to the oil seal lip.
(b) If the oil pump is installed to the cylinder block:
(1) Using a knife, cut off the oil seal lip.
(2) Using a screwdriver, pry out the oil seal.
NOTICE:
Be careful not to damage the crankshaft. Tape up the
screwdriver tip.

RELAY
Basically, an electrically operated
switch which may be normally
closed (1) or open (2).
