Likely Root Cause
Fix
Error 1
Heater circuit
shorted
1. Short in cable
2. Short in sensor
1. Repair/replace cable.
2. Replace sensor.
Error 2
Heater circuit open
1. Damaged sensor cable
2. Cable connector not fully
seated
1. Verify Sensor connector is fully seated
into unit.
2. Repair/replace Sensor or cable.
Error 3
Pump cell circuit
shorted
1. Short in sensor cable
2. Short in sensor
3. Sensor heater calibration
incorrect
4. Sensor overheating
EGT >1700º F
1. Repair sensor cable.
2. Replace sensor.
3. Perform sensor heater recalibration.
4. Move your sensor bung as far
downstream as possible OR add a heatsink
to isolate the sensor from the pipe.
Error 4
Pump cell circuit
open
1. Damaged sensor cable or
sensor connector not fully
seated
2. Sensor heater calibration
incorrect
1. Verify sensor connector is fully seated
into unit.
2.Repair/replace cable.
3. Perform complete heater calibration (not
just free air calibration). See section 4
Error 5
Reference cell
circuit shorted
1. Short in sensor cable
2. Short in sensor
1. Repair sensor cable.
2. Replace sensor.
Error 6
Reference cell
circuit open
1. Damaged sensor cable or
sensor connector not fully
seated
2. Damaged Sensor
1. Verify sensor connector is fully seated
into unit.
2. Replace sensor
Error 7
General System
error (typically a
software error).
1. Typically a software error
1. Reboot LC-1 by cycling power. Re-flash
unit if necessary.
Error 8
Sensor Timing error
(typically a
damaged sensor).
1. Sensor overheating.
(The Bosch LSU4.2 is rated to
operate at a sensor housing
temperature of < 900 degrees
(measured at the bung) for
maximum accuracy and control.
When this operating temperature
range is exceeded, the sensor
can no longer be accurately
controlled. )
Sensor is damaged
1a. Perform sensor heater recalibration;
1b. Move your sensor bung as far
downstream as possible. Right before the
cat, or 2-3 feet from the end of the tailpipe
are good locations; c. Add a heatsink to
isolate the sensor from the pipe. The HBX-
1 is an available accessory.
2. Replace sensor.
Error 9
Supply Voltage too
low
Supply voltage too low for
sensor regulation
Check your 12V connection for corrosion.
