Circuit description: Notes
The sensor built in the air pressure sensor ASSY detects an intake manifold pressure as a voltage. Also, the air pressure sensor ASSY is not affected by air pressure variation caused by a change in altitude or other factors because it detects pressure inside the intake manifold via absolute pressure instead of barometric pressure as reference.
| DTC No. | DTC detection condition | Suspected parts |
|---|---|---|
| P0107 | Vacuum sensor voltage is 0.610V or less for 2.0 seconds or longer. (1 -trip detection logic) |
|
| P0108 | Vacuum sensor voltage is 3.906V or more for 2.0 seconds or longer. (1-trip detection logic) |
NOTE:
After checking diagnostic code outputs, read the following menu items using the SSM4: [Each System] / [Engine Control System] / [Data monitor] / [Mani. Absolute Pressure] (Refer to
DATA MONITOR/ACTIVE TEST
)
| Intake manifold pressure | Content of malfunction |
|---|---|
| Approx. 0 kPa |
|
| 141 kPa or more |
