FUEL INJECTION SYSTEM

Fault code No.

Symptom

Open or short circuit detected from the atmospheric pressure sensor.

Used diagnostic code No. 02 (atmospheric pressure sensor)

Inspection operation item and probable cause Operation item and countermeasure

Reinstatement
method

Defective atmospheric pressure sensor.

Replace if defective.
1. Connect the pocket tester (DC 20 V) to the

atmospheric pressure sensor coupler ter-
minal as shown.

2. Set the main switch to “ON”.
3. Measure the atmospheric pressure sensor

output voltage.

4. Is the atmospheric air pressure sensor OK?

Reinstated by turn-
ing the main switch
ON.

Open or short circuit in wiring harness.

Repair or replace if there is an open or short
circuit.

Installed condition of atmospheric pressure
sensor

Check the installed area for looseness or
pinching.

Connected condition of connector

Inspect the coupler for any pins that may
have pulled out.
Check the locking condition of the coupler.

If there is a malfunction, repair it and connect it
securely.
