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] 

• non E
