Details

Replace the engine harness when its insulation cracks, wires melt, or sensors throw recurring electrical faults, since damaged wiring causes rough engine performance and a lit check-engine light.

• Replacement sign: Cracked or melted wire insulation, corroded connectors, or intermittent sensor fault codes.
• Approximate lifespan: Typically lasts 150,000 to 250,000 km depending on engine heat and operating conditions.
• Install requirement: Requires a qualified auto-electrician, with the battery disconnected and the wiring diagram verified.
