Appendix C: LC-1 Error Codes and Troubleshooting Tips
Error
Code Error Message 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 or
Cable connector not fully
seated
1. Verify Sensor connector is
fully seated into unit.
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
5. 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.
Repair/replace cable.
2. 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). Typically a software error 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. )
2. Sensor is damaged
1. a. Perform sensor heater
recalibration; b. 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.
