MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L8, LF]

Note

• Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See Troubleshooting Procedure.)

1. Connect the M-MDS to the DLC-2.

2. Turn the ignition switch to the ON position (Engine off).

3. Select MAP PID on the M-MDS.

4. Verify that the MAP PID (pressure) and barometric pressure are practically equal.

• If not as verified, perform the "Circuit Open/Short Inspection".

- If there is no open or short circuit, replace the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [L8, LF].)

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L8, LF].)

2. Inspect the following wiring harnesses for an open or short circuit. (Continuity Inspection)

Open circuit

• If there is no continuity, there is an open circuit. Repair or replace the wiring harness.

- MAP/boost air temperature sensor terminal A and PCM terminal 2AV

- MAP/boost air temperature sensor terminal C and PCM terminal 2AU

- MAP/boost air temperature sensor terminal D and PCM terminal 2AG

Short circuit

• If there is continuity, there is a short circuit. Repair or replace the wiring harness.

- MAP/boost air temperature sensor terminal A and power supply.

- MAP/boost air temperature sensor terminal C and body ground.

- MAP/boost air temperature sensor terminal D and power supply.

- MAP/boost air temperature sensor terminal D and body ground.
