Important: Twisted-pair wires provide an effective shield that helps protect sensitive
electronic components from electrical interference. Depending on application,
twisted-pair wires are used on wiring harnesses connecting the following
components:
• | The electronic ignition control module |
• | The manifold absolute pressure (MAP) sensor |
• | The powertrain control module (PCM) |
• | The vehicle speed sensor (VSS) |
In order to prevent electrical interference from degrading the performance
of the connected components, you must maintain the proper specification when
making any repairs to the twisted-pair wires shown :
• | The wires must be twisted a minimum of 9 turns per 30.5 cm
(12 in) as measured anywhere along the length of the wires. |
• | The outside diameter of the twisted wires must not exceed 6.0 mm
(0.236 in). |
