The manifold absolute pressure sensor detects the intake manifold pressure. The ECM determines the basic injection volume and injection advance timing based on the voltage output by the manifold absolute pressure sensor.
The manifold absolute pressure sensor monitors the absolute pressure inside the intake manifold (default is 0 kPa [0 mmHg, 0 in.Hg]). As a result, the ECM controls the air-fuel ratio so that it reaches the proper level under any driving conditions.

INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK070X.html) and initialization (HILUX_TGN26 RM000000TIN057X.html).
  3. After replacing the fuel supply pump assembly, the ECM needs initialization (HILUX_TGN26 RM000000TIN057X.html).
  4. After replacing an injector assembly, the ECM needs registration (HILUX_TGN26 RM0000012XK070X.html).
HINT:
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.
1.READ VALUE USING INTELLIGENT TESTER (MANIFOLD ABSOLUTE PRESSURE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.

  1. Read the value.

    OK:
    Same as the actual atmospheric pressure.
    HINT:
    1. Standard atmospheric pressure is 101 kPa. For every 100 m increase in elevation, pressure drops by 1 kPa. This varies by weather (high atmospheric pressure, low atmospheric pressure).
    2. Also, check "Atmosphere Pressure" in the Data List.


OK
Go to step 8

NG
Go to step 2

2.CHECK HARNESS AND CONNECTOR (MANIFOLD ABSOLUTE PRESSURE SENSOR - ECM)

  1. Disconnect the manifold absolute pressure sensor connector.

  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    C20-2 (PIM) - C114-5 (PIM)

    C20-3 (VC) - C114-13 (VC)
    		Always
    		Below 1 Ω
    C20-1 (E) - C114-14 (E2)
    		Always
