7.2. OAT SENSOR REPLACEMENT

The OAT sensor is located on the Left Hand Mirror (driver side). Before replacing the sensor, check if it is faulty. Remove the mirror and test the resistance with an ohmmeter

between terminals 5 & 6 on the connector. See the table below to compare the reading against actual temperatures.

Procedure:

1. Remove the mirror system from the truck (see 1), carrier glass assemblies (see 2) and the housing (see 3) from the mirror.

2. Remove the faulty OAT sensor by cutting the green and blue wires approximately 1/4” before the sensor and appropriately dispose the faulty OAT sensor.

3. Strip the ends of the wires on the remaining cable approximately 3/8" from the cut.

4. Use butt splice supplied and slide over one of the wires.

5. Separate the wire strands in a way that the wires fray as shown in the figure below.

6. Push the two wires (new OAT sensor & remaining cable) together to intertwine the two wire strands.

7. Slide the butt splice over the combined wires and center it.

8. Apply heat evenly around the length of the tubing from the center and out to the ends until the tubing recovers and the adhesive flows. Continue distributing the heat over the butt splice until the solder flows into the wire strands. Remove the heat and allow it to cool for a perfect connection.

9. Repeat step 4 - 8 above for the other wire.

10. Install OAT sensor as shown in 7.3.1

For Best Results: Use a heat device capable of producing a temperature of 500 °F. When using an open flame, do not isolate the flame on one area of the tubing. Make sure to distribute the heat evenly. Failure to heat the connector until the solder is melted will result in an inferior connection. Overheating the connector may cause damage to the tubing. The use of a liquid flux is recommended, especially with used wire.
