HINT: 

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

1. Disconnect the manifold absolute pressure sensor connector.
2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   C115-3 (VC) - C115-1 (E2)	Ignition switch ON	4.75 to 5.25 V
   C115-2 (PIM) - C115-1 (E2)	Ignition switch ON	3.0 to 5.25 V

4. Turn the ignition switch off and wait for at least 30 seconds.
5. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C115-3 (VC) - C115-2 (PIM)	Ignition switch off	171 to 189 kΩ
   C115-1 (E2) - Body ground	Always	Below 1 Ω

   Result
