Single
Fix for Multiple Nissan® O2 Sensor Codes
If one of the following vehicles comes into the
shop with the “Malfunction Indicator Lamp” (MIL) “ON”
and one or more of the following Diagnostic Trouble Codes (DTCs)
are stored in Engine Control Module (ECM), the repair may be as
simple as installing an additional ground sub-harness.

 Diagnosis
and Service Procedure
Review safety procedures in ALLDATA® RepairSM before beginning.
1. Check for poor grounding
using a Digital Volt-Ohm Meter (DVOM).
2. Measure the voltage drop
between the intake manifold ground bolt for the engine harness and
the right hand (RH) cylinder head.
3. At engine warm idle, place
the positive (red) meter lead on the intake manifold ground bolt
for the engine ECCS harness and the negative (black) lead on RH
cylinder head and measure the voltage.
• If the voltage is above 0.025V
(25 millivolts), install the sub-harness shown in Figure 1 to resolve
the incident. Continue with step two of this bulletin.
• If the voltage is less than
0.025V (25 millivolts), the problem will not be repaired with a
sub-harness and will require further diagnosis. Refer to the System
Diagnosis section in ALLDATA Repair.
 4.
Route the sub-harness from the RH cylinder head, on the
existing ECCS harness. Route it toward the center front of the engine
and then back toward the intake manifold collector (Figure 2).
5. Find the two threaded holes
in the RH cylinder head next to the negative battery cable attachment
point (Figure 3).
6. Secure the sub-harness end
with the two larger eyelets to these two threaded holes (Figure
3).
7. Use the two new hex bolts
to attach the sub-harness eyelets.
CAUTION: To prevent
damage, the sub-harness must be positioned more than 70 mm (2.8
in.) from the exhaust manifold.
8. Now attach the sub-harness
to the ECCS harness at four (4) places (Figure 4) using the wiring
clips listed in the parts information. Space the wiring clips out
as shown in Figure 4.
9. Secure the sub-harness
end with the two smaller eyelets. You'll attach them using two of
the existing ground bolts located on the intake manifold (Figure
3).
10. Trim the excess material
from the newly installed wiring clips.
