YES
▶ Go to "Check Fuel Pressure Test" as below
NO
▶ Repair or readjust as necessary and go to "Verification of Vehicle Repair" procedure
6.
Check Fuel Pressure Test
NOTE
-
Be cautious that Fuel is explosive and an empty fuel tank can still contain explosive gases.When working on fuel
system make sure to supply adequate ventilation to the work area. Do not smoke, and keep sparks and open
flames away.
-
The fuel system remains under pressure when the engine is not running. Release fuel system pressure before
disconnecting any fuel line to reduce the chance of presonal injury or fire damage to vehicle components.
1)
Start the engine and disconnect the fuel pump relay.
2)
Wait until fuel in fuel line is exhausted and the engine stalls.
3)
Turn the ignition switch OFF position.

4)
Install the special service tool for measuring the fuel pressure between the delivery pipe and the fuel feed hose.
5)
Connect the fuel pump relay.
6)
With fuel pressure applied, check the three is no fuel leakage from the fuel pressure gauge or connection part.
7)
Start the engine and measure the fuel pressure at idle.
Specification : 374 ~ 384 kpa (3.82 ~ 3.92 kg/㎠, 54.3 ~ 55.8psi)
8)
Stop the engine and check for a change in the fuel pressure gauge reading.
Specification : After engine stops, the gauge reading should hold for about 5 minutes.
9)
Is the measured fuel pressure within specification?
YES
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
NO
▶ Repair or replace according to the table below.
▶ And then, go to " Verification of Vehicle Repair" procedure.

VERIFICATION OF VEHICLE REPAIR
E8FA8100
After a repair, it is essential to verify that the fault has been corrected.
1.
Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
2.
Using a Scantool, Clear the DTCs
3.
Operate the vehicle within conditions noted in the freeze frame data or enable conditions
4.
Monitor that all rediness test have been verified as " Complete "

DTC P0315 SEGMENT TIME ACQUISITION INCORRECT
GENERAL DESCRIPTION
E6DFE6D5
The Crankshaft Position Sensor (CKPS) is a magnetic field sensitive type sensor that generates voltage using a sensor
and a target wheel mounted on the crankshaft; there are 58 slots in the target wheel where one is longer than the others.
During one crankshaft rotation there are 58 rectangular signals and one longer signal. The ECM calculates engine RPM
by using the sensor’s signal and controls the injection duration and the ignition timing. Using the signal differences caused
by the longer slot, the ECM identifies which cylinder is at top dead center.
DTC DESCRIPTION
E90F99E4
Checking tooth error correction under detecting condition, if the TEC is out of Threshold value, PCM sets P0315.

• Vehicle speed 〈 5kph( 3.106856 mph)
• Tec RPM stability timer 〉10sec
• 0℃(32 F)〈 coolant temp〈 110℃(230 F)
• Not active disabling faults
• Not key on disabling faults
Threshold value
• Distance driven without learning tooth error ≥
4000km(2485.484769 mile) or
• Maximum allowed number of tooth error
correction samples taken in the On The
Road(OTR)learning mode〈 250 or
• Sum of tooth error factors variation outside
calibratable range ≥ 250
Diagnosis Time

MIL On Condition
• 1 driving cycles
• CKPS
• Target wheel
• PCM
COMPONENT INSPECTION
E28BECE8
1.
Visually check CKPS and target wheel
1)
IG "OFF"
2)
Check CKPS and target wheel for deformation or damage visually
3)
Is the above items normal ?
YES
▶ Go to "Verification of Vehicle Repair" procedure.
NO
