        (to Manifold Absolute Pressure Sensor)

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

        Standard Voltage
        Tester Connection Switch Condition Specified Condition
        3 VC (+) - 1 E (-) Ignition switch ON 4.75 to 5.25 V

        If the result is not as specified, inspect the wire harness or ECM Click here.

      3. Connect the manifold absolute pressure sensor connector.

      Check the power supply.


      1. Turn the ignition switch to ON.

      2. Disconnect the vacuum hose from the manifold absolute pressure sensor.

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

        Standard Voltage
        Tester Connection Condition Specified Condition
        C56-28 (PIM +) - C55-28 (E2 -) 13.3 kPa (100 mmHg, 3.94 in.Hg) 0.0 to 0.3 V
        26.6 kPa (199 mmHg, 7.85 in.Hg) 0.2 to 0.6 V
        40 kPa (300 mmHg, 11.81 in.Hg) 0.4 to 0.8 V

        Tech Tips

        The values in the "Condition" column are gauge pressures.

        If the result is not as specified, replace the manifold absolute pressure sensor.

        Standard Voltage
        Tester Connection Condition Specified Condition
        C56-28 (PIM +) - C55-28 (E2)

        19.6 kPa (0.20 kgf/cm2, 2.84 psi)

        		 0.05 to 0.3 V

        39.2 kPa (0.40 kgf/cm2, 5.68 psi)

        		 0.25 to 0.55 V

        58.8 kPa (0.60 kgf/cm2, 8.53 psi)

        		 0.45 to 0.75 V

        78.5 kPa (0.80 kgf/cm2, 11.4 psi)

        		 0.65 to 0.95 V

        98.0 kPa (1.00 kgf/cm2, 14.2 psi)

        		 0.9 to 1.2 V

        Tech Tips

        The values in the "Condition" column are gauge pressures.

        If the result is not as specified, replace the manifold absolute pressure sensor.
