Poor Engine Performance / Engine in Limp-Home Mode / Stored ME Fault Codes
If you receive customer reports in the above model vehicles regarding poor vehicle performance, engine in limp-home mode or fault codes stored in the
ME-SFI control unit (N3/10), this may be caused by a temporary transition resistance in the Z sleeves area. To resolve, install an optimized throttle valve
wiring harness as per the following,
1.
Remove resonance wiring harness. Refer to testing / repair work in WIS Group 09.20.
2.
Remove lower section of intake manifold.
3.
Replace throttle valve wiring harness. Refer to testing / repair work in WIS Group 07.61.
4.
Install in reverse order.
Note:
Modified tightening pattern (Figure 1)/modified torque for intake manifold mounting bolts.

Stage 1 to 8 Nm
^
Stage 2 to 10 Nm

Stage 3 at 90° angle
The throttle valve stop must always be taught in again after the repair.
