Re: Trouble codes/beeps (SPRINT 290DC)
Well, you're in luck.... I just happen to be sitting here on the porch studying an EFI Course Technician's Guide right now....
LOW OIL LEVEL: The low oil level warning is activate when the remaining oil in the mounted oil resevoir tank drops below 50 fl. oz.... WARNING HORN EMITS A SERIES OF FOUR BEEPS.
ENGINE OVERHEAT: HORN SOUNDS CONTINUOUSLY
ENGINE OVERSPEED: INTERMITTENT BEEP until engine speed drops below MAXIMUM RPM.
ELECTRICAL SENSOR NOT FUNCTIONING: If the TPS, MAP, or CTS is not functioning, or is out of it's "pre-programmed diagnostic range", the warning horn will sound INTERMITTENTLY.
WATER IN FUEL WARNING: SERIES OF FOUR BEEPS.
These warnings were intended to be utilized with a "WARNING LIGHT GAUGE" (which provided additional information via lighted warning lights).
