Ambient Temperature Indicator
WARNING: This page is about a different car, the 2001 Acura 3.5RL and 2001 Acura 3.2TL. However, it is still accessible from the selected car via links, so may be relevant.
If indicator displays 888.8 for more than 2 seconds after selecting ambient temperature display mode, check for open in Brown/White wire between instrument cluster 30-pin connector "A" terminal No. 18 (3.2TL) or No. 19 (3.5RL) and ambient temperature sensor. See Figure. If circuit is okay, test sensor. See AMBIENT TEMPERATURE SENSOR . If sensor tests okay, replace instrument cluster.
