Hyundai Santa Fe (2006 year). Manual — part 637
FLA -614
FUEL SYSTEM
▶ Go to "Check fuel filter" as follows.
NO
▶ Substitute with a known - good HO2S and check for proper operation.
If the problem is corrected, go to "Verification of Vehicle Repair" procedure.
3.
Check the fuel filter of fuel pump
1)
IG "OFF" and disconnect the fuel pump connector.
2)
Start the engine and wait until fuel in fuel line is exhausted. After the engine stalls, IG "OFF"
3)
Remove the fuel pump assembly.
4)
Check the fuel filter for clogging by dust, a foreign substance.
5)
Is the fuel filter O.K.?
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
▶ Substitute with a known - good fuel filter and check for proper operation.
If the problem is corrected, 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. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.
VERIFICATION OF VEHICLE REPAIR
E7B398AA
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 "
5.
Are any DTCs present ?
YES
▶ Go to the applicable troubleshoooting procedure.
NO
▶ System is performing to specification at this time.

FUEL SYSTEM
2)
Check if HO2S is ensurely installed.
3)
Is the conditions of HO2S normal ?
YES
▶ Go to "Check the Signal waveform of HO2S" as follows.
NO
▶ Repair it and then go to "Verification of Vehicle Repair" procedure.
2.
Check the Signal waveform of HO2S
1)
IG "OFF" and connect HO2S connector.
2)
Engine start.
3)
After warming-up, monitor signal waveform of HO2S with scantool.?

4)
Is the sensor switching properly?
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
▶ Substitute with a known - good HO2S and check for proper operation.
If the problem is corrected, go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automaticallydetected and memorized by
PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

DTC P2197 HO2S SIGNAL STUCK LEAN (BANK 2 / SENSOR 1)
COMPONENT LOCATION
ECEB14C1
HO2S [Bank 2/Sensor 1]
LGLG506A
GENERAL DESCRIPTION
E3645AB8
In order to control emissions of the CO, HC and NOx components of the exhaust gas, heated oxygen sensor (HO2S),
mounted on the front side and rear side of catalytic converter, detects the oxygen content in the exhaust gas. The front
HO2S signal is used to control air/fuel ratio (closed loop fuel control) and the rear HO2S signal is used to monitor front
HO2S and catalyst for proper operation. The HO2S requires a minimum temperature to operate properly and provide a
closed loop fuel control system. The HO2S contains the heater element to reduce its warming-up time and ensure its
performance during all driving conditions. The oxygen sensor generates a voltage that indicates the difference between
the oxygen content of the exhaust stream and the oxygen content of ambient air. When the exhaust stream is “ rich,”
there is more oxygen in the ambient air than in the exhaust stream, so the voltage will be higher.
DTC DESCRIPTION
E21645C5
Checking output signals from HO2S under detecting condition, if HO2S’s signal is lean during power enrichment condi-
tions, PCM sets P2197. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving
cycle.
