DTC P2227 Barometric Pressure Circuit Range / Performance |
DTC P2228 Barometric Pressure Circuit Low Input |
DTC P2229 Barometric Pressure Circuit High Input |
DESCRIPTION
To detect atmospheric pressure, the built-in atmospheric pressure sensor in the ECM is used for the common rail system. Following the changes in the atmospheric pressure, the ECM corrects the fuel injection volume, timing and duration, and adjusts the common rail internal fuel pressure in order to optimize engine combustion.| DTC No. | DTC Detection Condition | Trouble Area |
| P2226 P2227 P2228 P2229 | Atmospheric pressure sensor malfunction (1-trip detection logic) | ECM |
INSPECTION PROCEDURE
- ПРИМЕЧАНИЕ:
- After replacing the ECM, the new ECM needs registration (See page Нажмите здесь) and initialization (See page Нажмите здесь).
- УКАЗАНИЕ:
- Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
| 1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2226 OR P2227 OR P2228 OR P2229) |
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the tester on.
Select the following menu items: Powertrain / Engine and ECT / DTC.
Read the DTCs.
- Result:
Result Proceed to DTC P2226, P2227, P2228 or P2229 is output A DTC P2226, P2227, P2228, P2229 and other DTCs are output B
