DESCRIPTION

By a built-in sensor unit, the manifold absolute pressure detects the intake manifold pressure as a voltage.
P001242E01

DTC No.
DTC Detection Condition
Trouble Area
P0107
The output voltage from the vacuum sensor remains 0.5 V or less for 0.5 seconds or more
(1 trip detection logic).
  1. Open or short in manifold absolute pressure sensor circuit
  2. Manifold absolute pressure sensor
  3. ECM
P0108
The output voltage from the vacuum sensor remains 4.5 V or more for 0.5 seconds or more
(1 trip detection logic).
  1. Open or short in manifold absolute pressure sensor circuit
  2. Manifold absolute pressure sensor
  3. ECM

HINT:
  1. DTC P0107 and P0108 are detected when the ignition switch is ON for approximately 2 seconds.
  2. When DTC P0107 or P0108 is detected, check the manifold absolute pressure by entering the following menus: Powertrain / Engine and ECT / Data List / MAP.

INSPECTION PROCEDURE

HINT:
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 help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1.READ VALUE USING INTELLIGENT TESTER (MAP)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester on.

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

  1. Read the MAP value.

    OK:
    Same value as the actual atmospheric pressure

HINT:
  1. Standard atmospheric pressure is 101 kPa (758 mmHg). For every 100 m (328 ft.) increase in altitude, pressure drops by 1 kPa (7.50 mmHg). Varies by weather (high atmospheric pressure, low atmospheric pressure).
  2. Also, check "Atmosphere Pressure" in the Data List.

2.CHECK TERMINAL VOLTAGE (MANIFOLD ABSOLUTE PRESSURE SENSOR)
A104038E04

  1. Disconnect the manifold absolute pressure sensor connector.

  1. Turn the ignition switch to ON.

  1. Measure the voltage between the terminals of the manifold absolute pressure sensor connector.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    B48-3 (VC) - B48-2 (E2)
    		Ignition switch ON
    		4.5 to 5.5 V
    B48-1 (PIM) - B48-2 (E2)
    		Ignition switch ON
    		4.0 to 5.0 V

4.CHECK WHETHER DTC OUTPUT RECURS (P0107 OR P0108)

  1. Connect the intelligent tester to the DLC3.

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

  1. Clear the DTC (Click here).

  1. Turn the ignition switch off.

  1. Turn the ignition switch to ON and wait for 2 seconds.

  1. Enter the following menus: Powertrain / Engine and ECT / DTC.

  1. Read DTCs.

    OK:
    No DTC output.

    		Condition
    		Specified Condition
    B48-3 (VC) - B8-67 (VCPM)
    		Always
    		Below 1 Ω
    B48-2 (E2) - B8-91 (EPIM)
    		Always
    		Below 1 Ω
    B48-1 (PIM) - B8-114 (PIM)
    		Always
    		Below 1 Ω

    Standard Resistance (Check for Short):
    Tester Connection
    		Condition
    		Specified Condition
    B48-3 (VC) or B8-67 (VCPM) - Body ground
    		Always
    		10 kΩ or higher
    B48-2 (E2) or B8-91 (EPIM) - Body ground
    		Always
    		10 kΩ or higher
    B48-1 (PIM) or B8-114 (PIM) - Body ground
