Service Procedure
1. Check the vehicle build date. Was the vehicle built on or before 4-Feb-2014 with an automatic transmission or
built on or before 19-Feb-2014 with a manual transmission?
(1). Yes – proceed to step 2.
(2). No – this article does not apply. Refer to Powertrain Control/Emissions Diagnosis (PC/ED) Manual for
normal diagnostics.

2. Visually inspect the engine harness for chafing against the intake manifold, near the throttle body. It may be
necessary to use a small mirror to inspect the back side of the harness where the harness may contact the
intake manifold. Is a harness chafe condition present? (Figure 1)
(1). Yes – proceed to step 3.
(2). No – this article does not apply. Refer to the PC/ED Manual for normal diagnostics.
Figure 1

3. Remove the harness protection and repair any damaged circuits. Refer to Cell 5 in the Wiring Diagram.
(1). When repairing damaged circuits, it is necessary to first disconnect the following electrical connectors.
Refer to the Wiring Diagram for component locations.
• High-pressure Fuel Pump/Fuel Injection Pump
• Mass Airflow/Intake Air Temperature (MAF/IAT) sensor
• Evaporative Purge Valve
• Engine Coolant Temperature (ECT) sensor
• Heated Oxygen Sensors (HO2S11 and HO2S12)
• Fuel Rail Pressure (FRP) sensor
• Camshaft Position (CMP11 and CMP12) sensors
• Variable Camshaft Timing (VCT11 and VCT12) solenoids
• Coil-on-plugs (COP), all 4

(2). Remove the air cleaner assembly. Refer to Workshop Manual (WSM), Section 303-12.
(3). Remove the bolt from ground G103.
(4). With the engine harness retainers disconnected from the top of the engine, the engine harness can be
lifted and moved forward to gain access to the circuits in the chafing location.
(5). Additional wire of approximately 2 mm (0.078 in.) must be added to the repaired circuits to maintain
proper circuit length. Refer to the Wiring Diagram Cell 5 and use the solder method.
4. Install protective shielding on the wire harness to prevent future circuit damage.
(1). Obtain a 15 cm (6 in.) length piece of 22 mm (7/8 in.) diameter flexible nylon split loom convolute and
Coroplast tape or equivalent. Secure the convolute to the engine wire harness. Coroplast tape or equivalent
must be applied in the location where the harness crosses the intake manifold near the throttle body and also
to secure the convolute to the wire harness. (Figure 2)
(2). Clean and install the ground G103 bolt and tighten to 10 Nm (89 lb-in).
