Inspection Procedure 4

The Ambient Temperature Screen Displayed "E °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 harness wires 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 it. Refer to Harness Connector Inspection.










STEP 2. Check the harness wires between ambient sensor connector A-29 and multi-center display connector C-09.

NOTE: After checking intermediate connector C-89, check the wires. If intermediate connector C-89 is damaged, repairer replace it. Refer to Harness Connector Inspection.

Q: Is the harness wires between ambient sensor connector A-29 and multi-center display connector C-09 in good condition?

YES: Go to Step 3.

NO: Repair them. The multi-center display should work normally.




STEP 3. Check the ambient sensor
1. Remove the front bumper.
2. Remove the ambient sensor connector.
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.
