FUEL SYSTEM
DTC P0152 HO2S CIRCUIT HIGH VOLTAGE (BANK 2 / SENSOR 1)
COMPONENT LOCATION
E73AFB1C
Refer to DTC P0151.
GENERAL DESCRIPTION
EFF8EE63
Refer to DTC P0151.
DTC DESCRIPTION
E92FC465
Checking output signals from HO2S under detecting condition, if an output signal is above 1.3V for more than predeter-
minate time, PCM sets P0152. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2
driving cycle.
DTC DETECTING CONDITION
E504302B
Item
Detecting Condition

Diagnosis Time
• Continuous
(more than 12.5 sec.failure for every 15 sec.test)
MIL On Condition
• 2 Driving Cycles
• Poor connection
• Short to battery in harness
• HO2S(B2/S1)
• PCM

DTC TROUBLESHOOTING PROCEDURES
FLA -275
SIGNAL CIRCUIT INSPECTION
E724643F
1.
IG "OFF" and disconnect HO2S(B2/S1) connector.
2.
IG "ON" and ENG "OFF"
3.
Measure voltage between terminal 1 of HO2S(B2/S1) 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.
COMPONENT INSPECTION
EFE36D91
1.
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
▶ Go to "Check HO2S" as below.
NO
FLA -276
FUEL SYSTEM
▶ 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.

DTC P0153 HO2S CIRCUIT SLOW RESPONSE (BANK 2 / SENSOR 1)
COMPONENT LOCATION
E5394BE4
Refer to DTC P0151.
GENERAL DESCRIPTION
E352B807
Refer to DTC P0151.
DTC DESCRIPTION
EAD91003
Checking output signals from HO2S under detecting condition, if PCM judges it’s signals too slow, PCM sets P0153.
MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
DTC DETECTING CONDITION
EC1F151B
Item
Detecting Condition
Possible cause
DTC Strategy
• Monitor HO2S’s response rate
Enable Conditions
• Engine warm-up sufficiently
• Engine run time > 60sec
• Drive at a steady speed between 45-55
mph(72-88 km/h)
• Engine Coolant > 70℃( 158 F)
• No disabling faults
Threshold value
• The calculated response rate is too slow
(out of threshold in PCM)
Diagnosis Time
• Continuous
MIL On Condition
• 2 Driving Cycles
• Poor connection
• Faulty HO2S
• Faulty PCM
