| DTC Code | DTC Name |
|---|---|
| 35 | Manifold Absolute Pressure / Barometric Pressure Circuit Malfunction |
DESCRIPTION
The manifold absolute pressure sensor generates voltage by the vacuum value as shown in the illustration. The voltage of the manifold absolute pressure sensor is one of the factors used to determine the injection volume and injection timing.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| 35 | Open or short in manifold absolute pressure sensor circuit for 2 sec. or more |

INSPECTION PROCEDURE
Tech Tips
If DTCs that are related to different systems are output simultaneously while terminal E2 is used as a ground terminal, terminal E2 may be open.
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
When using intelligent tester:
PROCEDURE
READ VALUE USING INTELLIGENT TESTER (INTAKE MANIFOLD PRESSURE)
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON.
Enter the following menus: Powertrain / Engine and ECT / Data List / PIM.

| The same as atmospheric pressure. |
Tech Tips
When DTC 35 is present, the type of malfunction can be determined based on the manifold absolute pressure (see below).
| Intake Manifold Pressure (kPa) | Malfunction |
|---|---|
| Approx. 0 |
