DTC P2227 Barometric Pressure Circuit Range/Performance (4JJ3 without DPD)

1. DTC P2227 description

The barometric pressure sensor is installed within the ECM. The barometric pressure sensor changes the signal voltage in accordance with changes in the barometric pressure. The boost pressure sensor is installed to the intake duct. The boost pressure sensor changes the signal voltage in accordance with changes in air pressure in the air intake piping. Diagnosis is performed inside the ECM by comparing the barometric pressure sensor signal with the boost pressure sensor signal. If the ECM detects that both signals are not within the specified range, the DTC is set.

Condition for setting the DTC

The ECM detects that the difference between the barometric pressure and the boost pressure is 10 kPa {1.5 psi} or more for 10 seconds or more.

3. Action taken when DTC P2227 sets

Euro4: The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type B (Euro4).
Except Euro4: The ECM illuminates the check engine warning light. Refer to Action taken when DTC sets - Type B (Except Euro4).

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC type definitions".

The ECM limits the fuel injection quantity.
The ECM inhibits the cruise control.
The ECM assumes a default barometric pressure value.

4. Condition for clearing DTC P2227

Euro4: Refer to Condition for clearing the MIL/DTC - Type A or Type B (Euro4).
Except Euro4: Refer to Condition for clearing the check engine warning light/DTC - Type A or Type B (Except Euro4).

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC type definitions".
