C 004 is detected if the following conditions is met :
If |actual boost pressure - barometric pressure| is above 140 hPa when the engine speed is below 210 rpm
When the C004 is detected repeatedly after clearing the DTC P1116 /C004, taking the below-listed check and inspection into consideration :
① Boost pressure and barometric pressure sensor
② CKP and CMP
③ Throttle flate device
To perform above troubleshooting procedure, go to " relevant DTC ITEMS "
- In order to check the boost pressure sensor and the barometric pressure sensor, Go to "Verification of Vehicle Repair" procedure among the tree on the left-hand side of the window
