DTC Detecting Condition and Trouble Area
DTC detecting condition Trouble area
DTC P2227:
Difference of barometric pressure value and intake manifold pressure value is higher than specified value while engine cranking.
(2 driving cycle detection logic)
• Manifold absolute pressure sensor performance problem
• Barometric pressure sensor in ECM
DTC P2228:
Barometric pressure signal less than specified value is detected.
(1 driving cycle detection logic)
• Barometric pressure sensor in ECM
DTC P2229:
Barometric pressure signal more than specified value is detected.
(1 driving cycle detection logic)
DTC Confirmation Procedure
P2227:
1) Connect scan tool to DLC with ignition switch OFF.
2) Turn ON ignition switch and clear DTC, pending DTC and freeze frame data by using scan tool and warm up engine to normal operating temperature.
3) Check DTC and pending DTC by using scan tool.
DTC P2228 / P2229:
1) Connect scan tool to DLC with ignition switch OFF.
2) Turn ON ignition switch and clear DTC by using scan tool and run engine for 1 min.
3) Check DTC and pending DTC by using scan tool.
DTC Troubleshooting
Step Action YES NO
1
Was “Engine and Emission Control System Check” performed?
Go to Step 2.
Go to Engine and Emission Control System Check:M13A with VVT .
2
Is DTC P2227 set?
Go to Step 3.
Substitute a known-good ECM and recheck.
3
MAP sensor check
1) Check MAP sensor and its circuit referring to DTC P0107: Manifold Absolute Pressure Circuit Low Input:M13A with VVT and/or DTC P0108: Manifold Absolute Pressure Circuit High Input:M13A with VVT .
Is check result satisfactory?
Substitute a known-good ECM and recheck.
MAP sensor or its circuit malfunction.
NOTE:
Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
