4. Troubleshooting code elimination 
(1) Eliminate the troubleshooting codes with a diagnostic instrument; 
(2) Disconnect the battery cathode for over 3 minutes (the engine needs initialization 
setup).

3. Troubleshooting procedure 

Step Description 

Yes 

No 

1 

Will the troubleshooting procedure be 
implemented? 

To Step 2 

Troubleshooting  
procedure 

2 

Check if relevant equipment show any of the 
following: 
•  The vacuum hose on the manifold is 

detached, damaged or suffers any bad 
contact 

•  Air intake manifold found of air leakage 
•  Throttle leakage 
Is there any of the above?  

Confirm 
repair 

To Step 3 

3 

Unfix the sensor fittings 
Check if the absolute pressure is close to 
0.103bar (0V) with an ADC 2000 diagnostic 
instrument.  

To Step 5 

To Step 4 

4 

Check the sensor signal circuit and if the 
circuit between the sensor and the ECM 
suffers any short circuit with the power source 
(anode).  

Confirm 
repair 

To Step 11 

5 

Check the sensor signal circuit and if the 
circuit between the sensor and the ECM 
suffers any of the following:  
•  Ground fault (Ω stage) 
•  Open circuit (Ω stage) 
Is there any of the above? 

Confirm 
repair 

To Step 6 

6 

Check the 5V reference voltage and if the 
circuit between the sensor and the ECM 
suffers any of the following: 
•  Ground fault (Ω stage) 
•  Open circuit (Ω stage) 
•  Short circuit with the power source (anode): 

(Voltage stage) 

Confirm 
repair 

To Step 7 

7 

Turn off the ignition switch 
Create a short circuit between the sensor signal 
terminal (Terminal B) and the ECM reference 
voltage terminal (Terminal C). Turn on the 
ignition switch and observe if the ADC2000 
diagnostic instrument displays an absolute 
voltage of 1.04bar (5V)?
