DI - 56 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

d. Measure the resistance between Pin 1 of fuel pressure
sensor connector A007 and Pin 68 of ECM connector A001.
Standard resistance:
Multimeter connection Standard value

A007(1)-A001(68) About 0Ω

Check if the result is ok?
Yes>go to Step 4.
No>check, repair or replace the ground harness of fuel pressure sensor.

4. Check the signal circuit of fuel pressure sensor
a. Ignition switch: LOCK.

b. Disconnect the cable of battery negative pole
c. Disconnect the connector A007 of fuel pressure sensor and ECM connector A001 separately

d. Measure the resistance between Pin 2 of fuel pressure
sensor connector A007 and Pin 69 of ECM connector A001.
Standard resistance:

Multimeter connection Standard value

A007(2)-A001(69) About 0Ω

Check if the result is ok?
Yes>go to Step 5.

No>check, repair or replace the power harness of fuel pressure sensor.
5. Check and replace the fuel pressure sensor.

a. Replace the fuel pressure sensor to make the engine running normally.
b. Use the diagnosis instrument to perform DTC confirmation procedure

c. Perform the procedure of reading the sensor data stream Confirm if the inspection result is ok
Check if the result is ok?

Yes> Replace the fuel pressure sensor.
NO>go to Step 6.
