ON-BOARD DIAGNOSTIC
DTC P0134
Except for GF4A-EL Models
DTCP0134
H02S circuit no activity detected
DETECTION
CONDITION
• PCM monitors input voltage from H02S when the following monitoring conditions are met. If input
voltage at PCM terminal 60 never
exceed 0.55
V for
73.5 seconds,
PCM determines that sensor
circuit is not activated.
MONITORING CONDITIONS
• Engine speed is
above 1,500 rpm.
• Engine coolant temperature is
above 80
"
C {158
* F}.
POSSIBLE
CAUSE
• H02S deterioration
• H02S heater malfunction
• Leakage in exhaust system
• Open or short to ground circuit between H02S terminal A (harness-side) and PCM terminal 60
• Insufficient compression
• Engine malfunction
Diagnostic procedure
STEP
INSPECTION
ACTION
1
VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Information
availability.
• Is any related Service Information available?
Yes
Perform repair or diagnosis according to available
Service
Information.
• If vehicle is not repaired, then go to next step.
No
Go to next step.
2
VERIFY CURRENT INPUT SIGNAL STATUS
• Warm up engine.
• Access FH02S PID using NGS tester.
• Verify PID while racing engine (in PARK or
NEUTRAL).
• Is PID reading okay?
—
More than 0.55 V
when suddenly
depressing accelerator pedal (rich
condition).
— Less than 0.55 V
just after release of
accelerator pedal (lean condition)
Yes
Go to Step 5.
No
Go to next step.
3
INSPECT INSTALLATION OF H02S
• Check if H02S is loosely installed.
• Is sensor installed securely?
Yes
Go to next step.
No
Install sensor securely, then go to Step 7.
4
INSPECT GAS LEAKAGE FROM EXHAUST
SYSTEM
• Visually check if any gas leakage is found
between exhaust manifold and H02S.
• Is there any gas leakage?
Yes
Repair or replace any faulty exhaust parts, then go to
Step 7.
No
• Inspect the following harnesses for open or short to
ground circuit
— H02S terminal A (harness-side) to PCM terminal
60 (harness-side)
• Repair or replace harness if necessary.
• If all items above are okay, replace faulty
sensor.
Then go to Step 7.
