DTC 35 Manifold Absolute Pressure / Barometric Pressure Circuit Malfunction
DESCRIPTION
The manifold absolute pressure sensor generates voltage according to the pressure 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.

INSPECTION PROCEDURE
If DTCs related to different systems that have terminal E2 as the ground terminal are stored simultaneously, there may be an open circuit between terminal E2 and body ground.
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
When using intelligent tester:
| 1.READ VALUE USING INTELLIGENT TESTER (INTAKE MANIFOLD PRESSURE) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Enter the following menus: Powertrain / Engine and ECT / Data List / PIM.
- OK:
- Value is same as atmospheric pressure.
- When DTC 35 is stored, the type of malfunction can be determined based on the manifold absolute pressure (see below).
| Intake Manifold Pressure (kPa) | Malfunction |
| Approx. 0 | |
| 192 or more | Open or short in VC circuit
Open in PIM circuit
Open in E2 circuit
|
| 2.CHECK CONNECTION OF VACUUM HOSE |
Check that the vacuum hose is securely connected and that there are no leaks from the connection.
- OK:
- The vacuum hose is securely connected and there are no leaks from the connection.
| | REPAIR OR REPLACE VACUUM HOSE |
|
|
| OK | |
| |
| CHECK FOR INTERMITTENT PROBLEMS
|
|
| 3.INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR |
Inspect the manifold absolute pressure sensor (See page ).
| | REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
|

|
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| C102-1 (VC) - C102-9 (E2) | Ignition switch ON | 4.75 to 5.25 V |
Text in Illustration| *a | Component with harness connected
(ECM) |
| 5.CHECK ECM (PIM VOLTAGE) |
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| C102-2 (PIM) - C102-9 (E2) | Ignition switch ON | 1.0 to 2.2 V |
Text in Illustration| *a | Component with harness connected
(ECM) |
| 6.CHECK HARNESS AND CONNECTOR (ECM - MANIFOLD ABSOLUTE PRESSURE SENSOR) |
Disconnect the manifold absolute pressure sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance (Check for Open):
| Tester Connection | Condition | Specified Condition |
| C83-3 (VC) - C102-1 (VC) | Always | Below 1 Ω |
| C83-2 (PIM) - C102-2 (PIM) | Always | Below 1 Ω |
| C83-1 (E) - C102-9 (E2) | Always | Below 1 Ω |
- Standard Resistance (Check for Short):
| Tester Connection | Condition | Specified Condition |
| C83-3 (VC) or C102-1 (VC) - Body ground | Always | 10 kΩ or higher |
| C83-2 (PIM) or C102-2 (PIM) - Body ground | Always | 10 kΩ or higher |
| C83-1 (E) or C102-9 (E2) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| CHECK FOR INTERMITTENT PROBLEMS
|
|
When not using intelligent tester:
| 1.INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR |
Inspect the manifold absolute pressure sensor (See page ).
| | REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
|
|
|
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:

Text in Illustration| *a | Component with harness connected
(ECM) |
| 3.CHECK ECM (PIM VOLTAGE) |
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| C102-2 (PIM) - C102-9 (E2) | Ignition switch ON | 1.0 to 2.2 V |
Text in Illustration| *a | Component with harness connected
(ECM) |
| 4.CHECK HARNESS AND CONNECTOR (ECM - MANIFOLD ABSOLUTE PRESSURE SENSOR) |
Disconnect the manifold absolute pressure sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
