Park Avenue V6-3.8L VIN K (1995)
Audible Warning Device: Description and Operation
Hi Coolant Temperature Warning
The coolant temperature sensor determines when the engine coolant is too hot and signals the Powertrain Control Module (PCM) at terminal C3/F13.
The PCM then grounds Multi-Function Chime (MFC) control module Terminal B5 and the TEMP Indicator in the Instrument Cluster. A fast-pulsed
chime sounds briefly and the TEMP Indicator lights and stays on even after the chime stops. The ignition switch provides a bulb check of the TEMP
Indicator when the ignition switch is in "BULB TEST" or "START."
