Inspection Procedure 4

The Ambient Temperature Screen Displayed "E0 °F" (Ambient Sensor Open Circuit) or "-E5 °F" (Ambient Sensor Short Circuit). These are Error Message.

Ambient Temperature Sensor Circuit:

CIRCUIT OPERATION
The ambient sensor signal sent to multi-center display.

TECHNICAL DESCRIPTION (COMMENT)
The ambient circuit is suspected to be open or short.

TROUBLESHOOTING HINTS
- Malfunction of the ambient sensor.
- Damaged wiring harness and connectors




STEP 1. Check the ambient sensor connector A-29 for damage.

Q: Is the ambient sensor connector A-29 in good condition?

YES: Go to Step 2.

NO: Repair or replace the connector. Refer to Harness Connector Inspection.










STEP 2. Check the wiring harness between ambient sensor connector A-29 (terminals 1 and 2) and multi-center display connector C-09 (terminals 14 and 12).

NOTE: After checking intermediate connector C-89, check the wires. If intermediate connector C-89 is damaged, repair or replace the wiring harness. Refer to Harness Connector Inspection.

Q: Is the wiring harness between ambient sensor connector A-29 (terminals 1 and 2) and multi-center display connector C-09 (terminals 14 and 12) in good condition?

YES: Go to Step 3.

NO: Repair the wiring harness. The multi-center display should work normally.

STEP 3. Check the ambient sensor

1. Remove the front bumper.




2. Remove the ambient sensor connector A-29.




3. Measure the resistance between the ambient connector sensor terminals at two or more temperature condition.

Q: Does the resistance value exist within the characteristic graph?

YES: There is no action to be taken.

NO: Replace the ambient sensor.
