D. N2O Pressure Transducer Faults
If the Nitrous Mode is set to FIX, the pressure transducer is ignored and no Nitrous faults should appear. If the
Nitrous Mode is set to ADJ or NON, when the nitrous button is pressed, the Control Box first checks to make sure
the readings from the pressure transducer are correct. One of the following two fault messages may be displayed. If
a fault message is displayed, the nitrous solenoid will not operate and the message will remain displayed until any key
is pressed to clear it or the engine is restarted.
ERROR: N2O press
too LOW! .
This screen may appear if the pressure in the N2O tank is zero, the transducer is unplugged, or there is a wiring
problem.
Important Note: If the bottle becomes empty, this message will be displayed and nitrous will be shut off to prevent
extra fuel from being added without nitrous!
ERROR: N2O press
over 2000psi .
This screen will appear if the pressure transducer senses a pressure above 1000psi for regulated systems or 2000psi for
non-regulated systems.
VIII. Control Box Troubleshooting
Stuck Button
When the Control Box is first turned on, all buttons are checked to verify that a button is not stuck on. If a button is
detected to be on during power up, the button will be disabled and the following message will be displayed until
another button is pressed. To verify if a button really is stuck on, re-power the box without pressing any buttons.
Button is Stuck!
Note: A common problem is a bad ground connection on the sled causing the box to keep resetting itself. If a button
is being pressed when this occurs, the “button stuck” message will be displayed. Start the sled without pressing a
button and see if the message goes away. If it is not present, start looking for a disconnected ground on the sled (see
Other Issues below).
If a button really is stuck on, the Control Box can still function and adjust fuel properly. The Control Box can be sent
back to Boondocker to be serviced.
Injector Errors
The Control Box monitors the signals from the sled’s ECU. If it detects signals on one set of wires but not the other, it
will detect a fault on that injector and display one of the two error messages.
MAG Inj Error
Missing or bad signal detected on the MAG side injector (yellow or tan wire).
PTO Inj Error
Missing or bad signal detected on the PTO side injector (green or brown wire).
If either of these errors occur, the Control Box will still function and it will still try to make fuel adjustments, but the
intermittent injector connection will need to be fixed. Check for loose terminals in the connectors and frayed wires. If
the problem cannot be fixed, contact Boondocker to determine if the Control Box and harness need to be sent back to
be inspected or serviced.
Note: Injector errors that occur infrequently (more than several minutes apart) may be ignored since they are likely
caused by sporadic electrical noise. Try rerouting the Control Box harness so it is kept away from ignition, fuel pump,
and stator wires. Verify that the sled’s factory ground wire is securely attached.
Prev Inj Error
This means a previous injector fault has occurred which has not yet been
cleared. Press any button to clear this.
