DESCRIPTION

The manifold absolute pressure sensor detects the intake manifold pressure. The ECM determines the basic injection duration and injection advance timing based on the voltage output from the manifold absolute pressure sensor.

DTC No.
DTC Detection Condition
Trouble Area
P0236
The manifold absolute pressure sensor output differs from atmospheric pressure sensor output by more than threshold for 2 seconds or more
(The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
  1. Open or short in manifold absolute pressure sensor circuit
  2. Manifold absolute pressure sensor
  3. ECM
P0237
P0238
Open or short in manifold absolute pressure sensor circuit for 2 seconds or more
(The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
  1. Open or short in manifold absolute pressure sensor circuit
  2. Manifold absolute pressure sensor
  3. ECM
УКАЗАНИЕ:
  1. DTC P0236 is set while idling for 10 seconds or more.
  2. DTC P0237 is set when the ignition switch is in the ON position.
  3. DTC P0238 is set when the ignition switch is in the ON position.
  4. When DTCs P0236, P0237 and/or P0238 are set, check the pressure by selecting the following menu items: Powertrain / Engine and ECT / Data List / PIM.

Reference:

Intake Manifold Pressure (kPa)
Malfunction
Approximately 0
  1. Short in PIM circuit
250 or more
  1. Open or short in VC circuit

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using an 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.
1.READ VALUE USING INTELLIGENT TESTER (MANIFOLD ABSOLUTE PRESSURE)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position.

  1. Turn the tester on.

  1. Enter the following menu items: Powertrain / Engine and ECT / Data List / PIM.

  1. Read the values.

    OK:
    Same value as the actual atmospheric pressure.
