1. DTC P2229 description
The barometric pressure sensor is installed within the ECM. The barometric pressure sensor changes the signal voltage according to changes in the barometric pressure. The ECM uses this voltage signal to adjust the fuel injection quantity and injection timing, as well as make altitude corrections. If the ECM detects an excessively high signal voltage, the DTC is set.
2. Condition for setting DTC P2229
Condition for running the DTC
- The battery voltage is 9 to 16 V.
- The ignition switch is ON.
- DTC P060B is not set.
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC P060B Internal Control Module A/D Processing Performance".
Condition for setting the DTC
- The ECM detects that the barometric pressure sensor signal voltage is 4.0 V or more for 3 seconds.
3. Action taken when DTC P2229 sets
- Euro4: The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type A (Euro4).
- Except Euro4: The ECM illuminates the check engine warning light. Refer to Action taken when DTC sets - Type A (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 EGR control.
- The ECM inhibits the turbocharger control.
- The ECM inhibits the cruise control.
- The ECM assumes a default barometric pressure value.
4. Condition for clearing DTC P2229
- 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".
