Test 15E - Outside Temperature Sensor
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST 15A or 19A before proceeding with this test.
- Connect DRB. Read OUTSIDE TEMPERATURE. If display is 195°F, go to next step. If display is not as specified, go to step 4).
- Unplug ambient temperature sensor, located behind front bumper, left of center. Turn ignition off, then on. Read OUTSIDE TEMPERATURE. If display is not temperature below 0°F, go to next step. If displayed temperature is below 0°F, replace sensor. Perform VERIFICATION TEST.
- Turn ignition off. Unplug Gray BCM connector, located above right kick panel. With DRB in ohmmeter mode, probe Violet/Light Green wire. If resistance is less than 5 ohms, repair short to ground in Violet/Light Green wire. If resistance is not less than 5 ohms, replace BCM. Perform VERIFICATION TEST.
- Unplug ambient temperature sensor, located behind front bumper, left of center. Connect jumper wire between harness connector terminals. Turn ignition off, then on. Read OUTSIDE TEMPERATURE. If display is not 195°F, go to next step. If display is 195°F, replace sensor. Perform VERIFICATION TEST.
- Connect jumper wire between Violet/Light Green wire and ground at harness connector. Turn ignition off, then on. Read OUTSIDE TEMPERATURE. If display is not 195°F, go to next step. If displayed temperature is 195°F, repair open Gray/Tan wire between sensor and BCM. Perform VERIFICATION TEST.
- Turn ignition off. Unplug Gray BCM connector. Using external ohmmeter, measure resistance of Violet/Light Green wire between sensor connector and terminal No. 10 of Gray BCM connector. If resistance is less than 5 ohms, replace BCM. If resistance is more than 5 ohms, repair open Violet/Light Green wire. Perform VERIFICATION TEST.
