Park Avenue V6-3.8L VIN K (1995)
Audible Warning Device: Component Tests and General Diagnostics
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."
