1400
What This Code Means
Continuity to engine ground measured on disconnected Wire 86; Engine faults out on OVERTEMP; High Temperature (Coolant temp greater than 246 ºF (119 ºC) for 1 second); High Temperature; Running Lean; Cranking with Low Fuel Pressure faults to rpm sensor loss; Running with low fuel pressure faults to rpm sensor loss; High temperature (Coolant temp greater than 246 ºF (119 ºC) for 1 second); High temperature; Cranking with low fuel pressure; Running with low fuel pressure; External display board is not able to communicate with main board; Main board does not see communication from display board; Overcrank; Low to no fuel pressure while cranking; Overspeed (Over 72 Hz for three seconds); Throttle stuck open; Overspeed (Over 75 Hz for one second); Total loss of control; Overcrank alarm; Overspeed (Over 72 Hz for three seconds with the throttle stuck open); Overspeed (Over 75 Hz for one second with the throttle stuck open, total loss of control); Low oil pressure while running
Possible Causes
- •Short to ground on Wire 86
- •Temperature switch contacts failed in a closed position
- •Inadequate airflow through the generator
- •Air Flow Impeded / Flow Issue
- •Very low fuel pressure while running
- •Low fuel pressure for 1200 ms preceding high temperature alarm
- •Low fuel pressure for at least 1200 ms
- •Ignition fault
- •Air pocket in fuel line
- •Dirty fuel
- •Low fuel pressure for 1200 ms
- •Air flow impeded / Flow issue
- •Very low fuel pressure while running (low for 1200 ms preceding high temperature alarm)
- •Internal Harness Loop Broken (internal to the display board)
- •Internal harness connecting external display board to main board has become disconnected
- •Engine/Starter Problem
- •No Fuel Pressure
- •Stuck throttle
- •Flow issue
- •Internal harness loop broken (external display board)
Suggested Actions
- 1Repair or replace Wire 86 as needed
- 2Check the inlet/outlet for debris.
- 3Check coolant sensor circuit for proper operation.
- 4Fuel pressure must be measured as low for 1200 ms preceding high temperature alarm to set this E-Code.
- 5Fuel pressure has to be measured as low for at least 1200 ms before the overcrank alarm is set.
- 6Check the inlet/outlet for debris
- 7Check coolant sensor circuit for proper operation
