Trouble Code Descriptions
Code 12 – Crank Trigger Error:
This code will register when the ECU has detected a problem with the
crank trigger signal. If any of the failure scenarios have been detected in the section above on the crank
sensor LED diagnostic, this code will be displayed
Code 13 – Cam Trigger Error:
The ECU is not getting an appropriate signal from the cam sensor. A
broken cam trigger wheel or a bad cam sensor could cause this error. This code will only be displayed on
sequential applications.
Code 14 – ECU Internal Failure:
This code is displayed when there has been a substantial failure inside
the ECU. Call technical support for further information.
Codes 21 & 22 – TPS High/Low:
See above description.
Codes 23 & 24 – Manifold Air Pressure High/Low:
These codes are set when the MAP sensor has gone
outside its specified range. This can be useful for a boosted application to trigger a check engine signal
when an over-boost situation has occurred. Alternately, it can be used to detect a short in the wires. When
this code is displayed, the TEC will be using the MAP Failure Default value for MAP calculations. As such,
there will be no load input to the TEC’s ECU, and the computer will enter into a “limp-home” mode.
Codes 25 & 26 – Coolant Temperature Sensor High/Low:
Once again, these codes are set when the
coolant temperature reading is outside its specified range. Use this light to warn of coolant temperatures that
are too high. When this code is displayed, the TEC will be using the CLT Failure Default value for coolant-
based calculations. As such, there will be no engine temperature input to the TEC’s ECU.
Codes 31 & 32 – Manifold Air Temperature Sensor High/Low:
Works identically to codes 25 & 26,
except for the MAT sensor.
Code 33 – Battery Voltage too High:
The battery voltage has exceeded 17 Volts. This can be caused by a
bad voltage regulator on the alternator.
Code 34 – Battery Voltage too Low:
The battery voltage has gone below 7.5 Volts. Check the state of
charge on the battery. Also check all power connections.
Code 35 – Knock too Long:
The ECU has recorded a level of engine spark knock (from the knock sensor)
for a duration that exceeds what was established in the software. This code is indicative of either poor fuel
quality, or extreme engine temperatures leading to spark knock. Some tuning will be required for the knock
sensor trouble codes, since all engines make noises that will trigger the knock sensor, but which are not
caused by spark knock.
Code 36 – Knock not Detected:
The ECU has not received any signal from the knock sensor. Check that
the sensor is plugged in.
Code 37 – EGO Lean too Long:
This code is set when the oxygen sensor reading is lean for a prolonged
period of time. Make sure the sensor has not come unplugged.
Code 38 – EGO Rich too Long:
This code is set when the oxygen sensor reading is rich for a prolonged
period of time. Make sure the sensor is not shorted to +12 Volts.
