6-1-54 GENERAL INFORMATION AND ENGINE DIAGNOSIS
DTC CONFIRMATION PROCEDURE
– Refer to DTC P0130 section.
INSPECTION
STEP ACTION YES NO
1 Was “ ENGINE DIAG. FLOW TABLE ” performed? Go to Step 2. Go to “ ENGINE DIAG.
FLOW TABLE ” .
2 Is there DTC(s) other than HO2S-1 (DTC P0133)? Go to applicable DTC
Diag. Flow Table. Replace HO2S-1.
DTC P0134 HEATED OXYGEN SENSOR (HO2S) CIRCUIT NO ACTIVITY
DETECTED (SENSOR-1)
WIRING DIAGRAM/CIRCUIT DESCRIPTION
– Refer to DTC P0130 section.
DTC DETECTING CONDITION POSSIBLE CAUSE
"
Engine warmed up.
"
While running under other than high load and high
engine speed conditions or at specified idle speed
(engine is in closed loop condition), HO2S-1 output
voltage is high or low continuously.
#
2 driving cycle detection logic, Continuous
monitoring.
"
“ RED ” or “ BRN/WHT ” circuit open or short
"
Heated oxygen sensor malfunction
"
Fuel system malfunction
"
Exhaust gas leakage
DTC CONFIRMATION PROCEDURE
– Refer to DTC P0130 section.
INSPECTION
STEP ACTION YES NO
1 Was “ ENGINE DIAG. FLOW TABLE ” performed? Go to Step 2. Go to “ ENGINE DIAG.
FLOW TABLE ” .
2 Is there DTC(s) other than Fuel system
(DTC P0171/P0172) and HO2S-1 (DTC P0134)? Go to applicable DTC
Diag. Flow Table. Go to Step 3.
3 Check HO2S-1 and Its Circuit.
1) Connect scan tool to DLC with ignition switch
OFF.
2) Warm up engine to normal operating
temperature and keep it at 2000 r/min. for
60 sec.
3) Repeat racing engine (Repeat depressing
accelerator pedal 5 to 6 times continuously and
take foot off from pedal to enrich and enlean
A/F mixture).
Does HO2S-1 output voltage deflect between
0.3 V and over 0.6 V repeatedly?
Go to DTC P0171 and
P0172 Diag. Flow Table
(Fuel System Check). Check “ RED ” and
“ BRN/WHT ” wires for
open and short, and
connections for poor
connection. If wires and
connections are OK,
replace HO2S-1.
