DTC P2226 Barometric Pressure Circuit |
DTC P2228 Barometric Pressure Circuit Low Input |
DTC P2229 Barometric Pressure Circuit High Input |
DESCRIPTION
The ECM uses its built-in atmospheric pressure sensor to detect atmospheric pressure. 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 P2228 P2229 | Atmospheric pressure sensor malfunction (1 trip detection logic) | ECM |
INSPECTION PROCEDURE
- HINT:
- Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.
- NOTICE:
- If the ECM is replaced, the new ECM needs initialization (Toyota Fortuner RM000000TIN04NX.html).
