4)
Is the sensor switching properly?
YES
▶ Go to "Check HO2S" as below.
NO
▶ Substitute with a known - good HO2S and check for proper operation.
If the problem is corrected, go to "Verification of Vehicle Repair" procedure.
2.
Check HO2S
1)
IG "OFF" and disconnect HO2S connector.
2)
Check that the HO2S is securely installed.
3)
Check the HO2S for contamination or damage
4)
Is the sensor normal?
YES
▶ Substitute with a known - good PCM and check for proper operation.
If the problem is corrected, 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 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
E8544C8A
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.

COMPONENT LOCATION
E47EE366
Refer to DTC P0137.
GENERAL DESCRIPTION
EDFEEB95
Refer to DTC P0137.
DTC DESCRIPTION
E1CC9CD2
Checking output signals from HO2S under detecting condition, if an output signal is above 1.3V for more than predeter-
minate time, PCM sets P0138. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2
driving cycle.

SIGNAL CIRCUIT INSPECTION
E63979A1
1.
IG "OFF" and disconnect HO2S(B1/S2) connector.
2.
IG "ON" and ENG "OFF"
3.
Measure voltage between terminal 1 of HO2S(B1/S2) harness connector and chassis ground.
Specification : Approx. 3.5V - when pumping current is ON
Approx. 0.45V - when pumping current is OFF
4.
Is the measured voltage within specification?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ Repair short to battery in harness, and go to "Verification of Vehicle Repair" procedure.
