The following chart gives the most likely solution(s) to each possible error.
CLEARING HISTORY ERRORS
There are two ways to clear an error. First, the code will erase after 10 key cycles. Second, is to simply
navigate to the message screen and push the joystick down to clear the codes.
WHAT IT MEANS
There is no reading for the Throttle
Position Sensor.
There is no reading for the Manifold
Air Pressure Sensor.
There is no reading for the Inlet Air
Temperature Sensor. The ECU will
default to 275° when open.
There is no reading for the Engine
Coolant Temperature Sensor. The
ECU will default to 275° when open.
The Atomic is receiving the wrong
voltage. The unit is measuring
either less than 9 volts or greater
than 16 volts.
Excessive Injector Duty Cycle
There is no reading for the Fuel
Pressure Sensor.
A. "NOT CONNECTED" indicates
that no sensor is detected.
B. "ERROR" indicates that the sen-
sor has failed.
This code will set if there is an issue
with Fuel Pump Cavitation (similar
to vapor lock). It can only set when
running a returnless fuel system. This
may occur when the commanded
fuel pressure (from the ECU) is
different than the fuel pressure (at
the sending unit).
CLEAR FLOOD
If a flood condition occurs, turn the key on then press the accelerator to wide-open throttle. This tells
the ECU to turn off the injectors. Crank the engine to clear the flood condition until the engine starts
(release the throttle open start-up).
Note: The TPS is self calibrating so the key must be in the On position prior to pressing the accelerator.
PROBABLE CORRECTION(S)
The sensor may be at fault. Note that the TPS is integral
of the throttle body.
The sensor maybe at fault. Note that the MAP sensor is
integral of the throttle body.
The sensor may be at fault. Note that the IAT sensor is
integral of the throttle body.
Check to see that the sensor is properly installed and
plugged in. If the sensor is connected but there is no
signal, it will need to be replaced.
Check that the Atomic has power and ground directly
from the battery. Also be sure the vehicle's battery and
charging system are in proper working order.
If you are running a returnless fuel system your en-
gine's needs may exceed the Atomic's maximum capa-
bilities. If you are running a return system check to see
that you are maintaining the recommended fuel pres-
sure. If you have adequate fuel pressure the engine
needs may exceed the Atomic's system capabilities.
The sensor will need to be replaced.
A. Check to see that the sensor is securely plugged
into the system.
B. The sensor will need to be replaced.
This means you need to review your fuel pump system
and confirm that your application meets the requirements
to run a returnless (PWM) system. Also check the filters,
the sock in the tank and inspect the lines for any kinks
or pinches that would affect the fuel flow and pressure
of the system. If everything checks okay and the code
continues, you may need to move to an in-tank pump,
or use a regulated (return) fuel system.
DIAGNOSTICS
There is a self-diagnosing system built into the Atomic EFI. Each covered parameter can show a status
in one of three ways.
“OK”: the parameter is functioning normally.
“Error C”: there is currently an error occurring.
“Error H”: there was previously an error that has been remediated within the last ten ignition cycles.
