Cause
These concerns may be caused by engine harness contact with under hood
components.
Shown below are areas that should be inspected for this concern.
Inspect the engine harness as it crosses over top of the Camshaft Carrier
Cover.
Harness damage can occur at any point across the Camshaft Carrier Cover.
Typical inspection locations shown below.
Example of engine wiring harness damage at Camshaft Carrier Cover shown below.
Inspect the engine harness at the Lower Air Cleaner Housing as shown below.
Example of engine harness damage, Lower Air Cleaner Housing removed shown below.
Inspect the engine harness at the Inlet Radiator Hose Bracket and Left Front Coil Spring stud as shown below.
Note: Under normal driving conditions, the engine will rock back and forth in its mounts.
This may result in harness contact with this bracket that may not be present during engine o inspections.
Careful visual inspections are necessary to isolate areas of contact.
It may be necessary to disconnect several engine harness connections to reposition the harness for inspections.
Inspect the engine harness at the Left Front Upper Control Arm Bushing as shown below.
Correction:
If engine wiring harness contact is isolated during inspection, use a seam ripper type tool to carefully inspect for
internal wiring damage.
If found, repair the damaged wiring following the SI wire to wire repair procedures.
Once repaired, protect the engine wiring harness at all points listed in this PI using Woven Polyester (PET)
Electrical/Anti-Abrasive Tape.
This tape may be purchased at kent-automotive.com Item# 1089482.
