FUEL SYSTEM
▶ Blocking in intake manifold and injector caused by any foreign substance
2)
Has a problem found?
YES
▶ Repair or replace it, and go to "Verification of Vehicle Repair" procedure.
NO
▶ Go to " Check fuel pressure" as follows.
2.
Check fuel pressure
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 systempressure before
disconnecting any fuel line to reduce the chance of presonal injury orfire 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
▶ Go to "Check fuel leakage in injector" procedure.
NO
▶ Repair or replace according to the table below.
▶ And then, go to " Verification of Vehicle Repair" procedure.

Condition
Possible Cause
Suspected area
Clogged filter
Fuel filter
Fuel pressure too low
Fuel leak on the fuel-pressure
regulator that is assembled on fuel
pump because of poor seating of
the fuel-pressure regulator
Fuel pressure regulator
Fuel pressure too high
Sticking fuel pressure regulator
Fuel pressure regulator
Fuel pressure drops slowly after
engine is stopped
Injector leak
Injector
Fuel pressure drops immediately
after engine is stopped
The check valve within the fuel
pump is open
Fuel pump
3.
Check fuel leakage in injector
1)
IG "OFF" after checking the fuel pressure test.
2)
Stop engine and check for a change in the fuel pressure gauge reading for 5 minutes.
Specification : After engine stops, fuel gauge reading is maintained for 5 minutes.
3)
Is the fuel gauge reading within specification?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ There is a fuel leakage in injector. Repair or replace it, and go to " Verification of Vehicle Repair" procedure.
COMPONENT INSPECTION

1.
Check PCV
1)
IG "OFF" and remove PCV valve from cylinder head
2)
With engine idling, block PCV valve and confirm that vacuum is felt.
3)
Insert thin stick into the screwed PCV valve and verify that the plunger is moving.
4)
Is the PCV valve normally moving?
YES
▶ Go to "Check PCSV as follows.
NO
▶ Replace it, and go to "Verification of Vehicle Repair" procedure.
2.
Check PCSV
1)
IG "OFF" and disconnect PCSV and vacuum hose.
2)
Connect hand-vacuum gage with PCSV and supply vacuum to it.

3)
Is the vacuum maintained ?
YES
▶ Go to " Check injector" as follows.
NO
▶ Repair or replace it, and go to " Verification of Vehicle Repair" procedure.
3.
Check injector
1)
IG "OFF" and disconnect injector.
2)
Check it for blocking caused by any foreign substance.
3)
Measure resistance between terminals 1 and 2 of Injector connector.(Component side)
SPECIFICATION :
Temp
Coil’s resistance
20℃(68 F)
13.8 ~ 15.2 Ω
4)
Is the measured resistance within specification?
YES
▶ Go to "Check sensor/actuator related to fuel system" as follows
NO
▶ Repair or replace it, and go to "Verification of Vehicle Repair" procedure.
4.
Check sensor/actuator related to fuel system
1)
Check the signal of sensor/actuator related to fuel system(HO2S, MAFS,MAPS, TPS, ECTS, PCSV, Injector and
so on) ( Refer to each DTC diagnostic procedure)
2)
Are all of these items normal ?
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.
NO
▶ Repair it, and go to "Verification of Vehicle Repair" procedure.

DTC P0196 ENGINE OIL TEMP. SENSOR RANGE / PERFORMANCE
COMPONENT LOCATION
E2609C65
OCV [Bank 2]
OTS
OCV [Bank 1]
LGLG500A
GENERAL DESCRIPTION
E4B4433D
The fluid of the CVVT is the engine oil and its density changes according to the engine oil temperature. At this time the
Oil Temperature Sensor (OTS) helps compensation against the temperature differences. The Oil Temperature Sensor
measures the engine oil temperature before the engine oil comes into the Oil-flow Control Valve (OCV).
According to the measured temperature, the Engine Control Module (ECM) compensates the oil-flow control valve oper-
ation time.
DTC DESCRIPTION
E70307F1
Checking the oil temperture , coolant temperature and intake air temperature every 25 sec. under detecting condition, if
the difference in temperature at start-up exceeds threshold value, PCM sets P0196.
DTC DETECTING CONDITION
E86D378A
Item
Detecting Condition
Possible cause
DTC Strategy
• Determines if the oil temperature value is rational,
compared to coolant and intake air temperature.
Enable Conditions
• Engine run time after startup〈 30 sec
• Minimum soak period required 〉270 min
Threshold value
• The difference in temperature between oil and
coolant temperatures at startup. 〉 35℃(63 F)
• The difference in temperature between oil
temperature and intake air temperature at
startup 〉 35℃(63 F)
Diagnosis Time
• Continuous
(More than 12.5 sec.failure for every 25 sec.test)
MIL On Condition
• No MIL ON (DTC only)
• Poor connection
• Open or short in harness
• Faulty OTS
• PCM
