C-07, Manifold Absolute Pressure Solenoid Circuit  

Result  

Cause Of Fault  

E01  

•  Defective component:  
Vacuum hose  
or  
P23 Sensor - Absolute Pressure, Intake Manifold  

 

Note:  

Check the hoses for leakage or blockage before replacing the component.  

 

 
 
 
 

E02  

•  Short circuit to ground/interruption of circuit between:  
P23 Sensor - Absolute Pressure, Intake Manifold  
Wiring Harness Connector Terminal B  
&  
K57 Control Unit - Multec  
Wiring Harness Connector Terminal A7  

or  

•  Defective component:  
K57 Control Unit - Multec  

 

 
 
 
 

E03  

•  Short circuit to voltage between:  
P23 Sensor - Absolute Pressure, Intake Manifold  
Wiring Harness Connector Terminal B  
&  
K57 Control Unit - Multec  
Wiring Harness Connector Terminal A7  

or  

•  Defective component:  
K57 Control Unit - Multec  

 

 
 
 
 

E04  

•  Short circuit to voltage/interruption of circuit between:  
P23 Sensor - Absolute Pressure, Intake Manifold  
Wiring Harness Connector Terminal A  
&  
K57 Control Unit - Multec  
Wiring Harness Connector Terminal D15  

or  

•  Defective component:  
K57 Control Unit - Multec  

 

 
 
 
 

E05  

•  If the nominal value is reached during one of the measurements, the component/control unit that has been disconnected immediately before that measurement is defective.  

 

 
 
 
 

E06  

•  If the nominal value is not reached with any of the measurements, this indicates that one of the following faults is present:  
Short to voltage/ground/interruption of circuit between:  
P23 Sensor - Absolute Pressure, Intake Manifold  
Wiring Harness Connector Terminal C  
&  
K57 Control Unit - Multec  
Wiring Harness Connector Terminal D8  
or  
Defective component:  
K57 Control Unit - Multec
