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.
