Wait-to-Start Lamp Warning Lamp

Fig. 12 Wait-to-Start And Water-in-Fuel Warning Lamp Location:

DESCRIPTION
The wait-to-start warning lamp is turned ON and OFF by the Powertrain Control Module (PCM) based on the intake manifold air temperature sensor input.

OPERATION
The lamp is turned ON when the ignition is first activated. It will remain on for two seconds as a bulb test. If the PCM reads intake manifold air temperature below 15-19°C (59-66°F), it will turn the wait-to-start warning lamp on for the air heater preheat cycle. The lamp stays on until the preheat cycle is over.

The wait-to-start lamp will flash ON and OFF if the intake manifold air temperature sensor input to the PCM is below minimum value or above maximum value. The PCM stores a DTC when these conditions occur.
