Appendix B: PSB-1 Error Codes and Troubleshooting Tips
Error
Code Error
Message Likely Root Cause Fix
Error 1 Heater circuit
shorted Short in sensor Replace sensor.
Error 2 Heater circuit
open 1. Damaged sensor
cable or sensor.
2. Sensor connector not
fully seated and locked
into position. 1. Verify that all sensor
connectors are fully seated and
locked into position.
2. Replace sensor
3. Replace sensor cable.
Error 3 Pump cell
circuit shorted 1. Short in sensor
cable
2. Short in sensor
3. Sensor calibration
incorrect 1. Replace sensor cable.
2. Replace sensor.
3. Perform sensor recalibration.
Error 4 Pump cell
circuit open 1. Damaged sensor
cable or sensor.
2. Connectors not fully
seated
3. Sensor calibration
incorrect 1. Verify that all sensor
connectors are fully seated and
locked into position.
2. Perform sensor calibration
3. Replace sensor cable.
4. Replace sensor.
Error 5 Reference cell
circuit shorted 1. Short in sensor
cable
2. Short in sensor 1. Replace sensor cable.
2. Replace sensor.
Error 6 Reference cell
circuit open 1. Damaged sensor
cable or sensor.
2. Connectors not fully
seated 1. Verify that all sensor
connectors are fully seated and
locked into position.
2. Replace sensor.
3. Replace sensor cable.
Error 7 System error System error Reboot PSB-1 by cycling
power.
Error 8 Sensor
Timing error
(typically a
damaged
sensor). 1. Sensor over-heating
or over-cooling (error
condition only occurs
at wide open throttle )
2. Sensor is damaged 1. Perform sensor calibration.
2. Move sensor bung as far
downstream as possible.
3. Add an HBX-1 (p/n 3729) to
isolate the sensor from the
pipe.
4. Replace sensor.
Error 9 Supply
Voltage too
low Supply voltage too low
for sensor regulation 1. Verify you have 12V at your
power source and the circuit
can support a 3 amp draw.
In an O2 error state, all relay functions are automatically
disabled.
