P1147 HO2S2
P1147 HO2S2
DescriptionINFOID:0000000001671017
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the heated oxygen sensor 1 are
shifted, the air-fuel ratio is controlled to stoichiometric, by the signal
from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates volt-
age from approximately 1V in richer conditions to 0V in leaner condi-
tions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.
DTC LogicINFOID:0000000001671018
DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the heated oxygen sensor 1. The oxygen
storage capacity of the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the maximum voltage of the sensor
is sufficiently high during the various driving condition such as fuel-
cut.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT-III?
Do you have CONSULT-III?
YES >> GO TO 2.

IGNITION SIGNAL
Component Inspection (Ignition Coil with Power Transistor)
INFOID:0000000001671110
1.CHECK IGNITION COIL WITH POWER TRANSISTOR-I
1. Turn ignition switch OFF.
2. Disconnect ignition coil harness connector.
3. Check resistance between ignition coil terminals as follows.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning ignition coil with power transistor.
2.CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION:
Do the following procedure in the place where ventilation is good without the combustible.
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT-III to release fuel pressure, or fuel pressure applies again during the following pro-
cedure.
4. Start engine.
5. After engine stalls, crank it two or three times to release all fuel pressure.
6. Turn ignition switch OFF.
7. Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
8. Remove ignition coil and spark plug of the cylinder to be checked.
9. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
10. Connect spark plug and harness connector to ignition coil.
11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -
0.66 in) between the edge of the spark plug and grounded metal
portion as shown in the figure.
12. Crank engine for about three seconds, and check whether spark
is generated between the spark plug and the grounded metal
portion.
CAUTION:
 Do not approach to the spark plug and the ignition coil
within 50 cm (19.7 in). Be careful not to get an electrical
shock while checking, because the electrical discharge
voltage becomes 20kV or more.
 It might cause to damage the ignition coil if the gap of more than 17 mm 0.66 in) is taken.
NOTE:
When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace malfunctioning ignition coil with power transistor.

FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)
If the engine speed is above 2,500 rpm under no load [for example, the shift lever position is P or N (A/T),
Neutral (M/T) and engine speed is over 2,500 rpm] fuel will be cut off after some time. The exact time when the
fuel is cut off varies based on engine speed.
Fuel cut will be operated until the engine speed reaches 2,000 rpm, then fuel cut will be cancelled.
NOTE:
This function is different from deceleration control listed under Multiport Fuel Injection (MFI) System, EC-38,
"System Description".

FUEL PRESSURE RELEASE
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT-III.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
With CONSULT-III
1. Remove fuel pump fuse located in IPDM E/R.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
CAUTION:
 Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
 The fuel hose connection method used when taking fuel pressure check must not be used for other
purposes.
 Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
 Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C,
etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes in
manifold vacuum.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because C11 models do not have fuel return system.
1. Release fuel pressure to zero.
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.
 : To quick connector
 : To fuel tube (engine side)
 C: Clamp
 Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).
 To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.
 Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.
 Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose.
 Do not twist or kink fuel hose because it is plastic hose.

1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Check EVAP canister as follows:
a. Block port (B). Orally blow air through port (A).
Check that air flows freely through port (C).
b. Block port (A). Orally blow air through port (B).
Check that air flows freely through port (C).
3. Visually inspect the fuel check valve for cracks, damage, loose connections chafing and deterioration.
4. Check fuel check valve as follows:
a. Blow air through connector on the fuel tank side. A considerable
resistance should be felt and a portion of air flow should be
directed toward the EVAP canister side.
b. Blow air through connector on EVAP canister side. Air flow
should be smoothly directed toward fuel tank side.
c. If fuel check valve is suspected or not properly functioning in
step 1 and 2 above, replace it.
5. Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.
a. Wipe clean valve housing.
b. Check valve opening pressure and vacuum.
c. If out of specification, replace fuel filler cap as an assembly.

DIAGNOSIS AND REPAIR WORKFLOW
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
