Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




If the control module receives a signal from the boost pressure sensor which is lower than 0.2 V (low signal) or higher than 4.85 V (high signal) it is interpreted as a fault and ECM-1600 is stored.

Substitute value
Boost pressure control runs in an open-loop, in other words set duty cycles are generated regardless of boost pressure.

Possible source

Signal too high:
- contact resistance in terminals
- short-circuit to supply voltage in the signal cable
- open-circuit in signal cable
- defective boost pressure sensor

Signal too low:
- short-circuit to ground in the signal cable
- defective boost pressure sensor

Fault symptom[s]
- none
