• If the exhaust gas pressure sensor is replaced, always perform each adjustment procedure using the following steps.

STEP

ACTION

PAGE/CONDITION

1

Replace the exhaust gas pressure sensor/exhaust gas pressure correction temperature sensor.

—

2

Start the engine.

Verify that the MIL does not illuminate.

3

Switch the ignition to off.

—

4

Switch the ignition to on (Engine off).

—

5

Perform KOEO self-test procedure.

(See KOEO/KOER SELF TEST [MZR-CD 2.2].)

6

Perform exhaust gas pressure sensor data reset procedure.

(See EXHAUST GAS PRESSURE SENSOR DATA RESET [MZR-CD 2.2].)

7

Switch the ignition to off.

—

8

Wait for 20 s.

—

9

Start the engine.

—

10

Perform diesel particulate filter assessment procedure.

Engine coolant temperature 60 °C {140 °F} or more

(See DIESEL PARTICULATE FILTER ASSESSMENT [MZR-CD 2.2].)

11

Switch the ignition to off.
