This DTC sets when either of the following conditions are present. When the throttle intake pressure value does not correlate with the barometric pressure and the manifold absolute pressure value at ignition ON. When the turbocharger boost pressure sensor does not correlate with the BARO sensor at idle and the TCBP sensor and MAP sensor fail to correlate while driving.
Item | Detecting Condition | Possible Cause | |
Case 1 | DTC Strategy |
•
Range Check, High | 1. Poor connection 2. Leakage test of surge tank 3. Leakage test of intercooler(hose) 4. Damaged turbocharger boost pressure /air cooler temperature sensor 5. Contaminated or blocked turbocharger boost pressure /air cooler temperature sensor 6. Slow responding turbocharger boost pressure /air cooler temperature sensor sensor |
