Appendix E: 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.
2. Cable connector not fully seated
3. Sensor
Damaged
1. Inspect sensor cable for rips or tears.
2. Verify Sensor is fully seated into
connector, make sure it ‘clicks.’
3. Replace Sensor
Error 3 Pump cell circuit
shorted 1. Short in sensor cable
2. Short in sensor
3. Sensor
overheating
4. EGT >1700º F
1. Repair sensor cable.
2. Replace
sensor.
3. 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.
2. Cable connector not fully
seated
3. Sensor Damaged
1. Inspect Sensor cable for rips or tears.
2. Verify Sensor is fully seated into
connector, make sure it ‘clicks.’
3. Replace Sensor
Error 5 Reference cell
circuit shorted 1. Short in sensor cable
2. Short in sensor 1. Inspect sensor cable for rips or tears.
2. Replace
sensor.
Error 6 Reference cell
circuit open 1. Cable connector not fully
seated
2. Damaged sensor cable
3. Damaged Sensor
1. Verify Sensor is fully seated into
connector, make sure it ‘clicks.’
2. Inspect sensor cable for rips or tears.
3. Replace
sensor
Error 7 General System
error (typically a
software error). Software error Reboot LM-2 by cycling power.
Reload firmware 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
3. Overly Rich condition
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.
3. Correct Tune and recalibrate the
sensor.
Error 9 Supply Voltage
too low Supply voltage too low for sensor
regulation Check your 12V connection for corrosion.
