DTC P2262:00 [SKYACTIV-D 2.2]

DTC P2262:00	Small-type turbocharger area control system: turbocharger malfunction
DETECTION CONDITION	• The PCM detects that the boost pressure is low even though the exhaust gas pressure is high while the boost control is performed using the small-type turbocharger.
FAIL-SAFE FUNCTION	• Fully open the Regulating solenoid valve. • Inhibits the auto diesel particulate filter regeneration control. • Inhibits the compulsory diesel particulate filter regeneration control. • Inhibits the EGR control. • Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE	• Exhaust gas pressure sensor No.1 malfunction • MAP sensor No.2 malfunction • Compressor bypass valve malfunction ― Compressor bypass valve fell off • Small-type turbocharger malfunction ― Turbine blade or compressor blade damage ― Runout, loss, or sticking due to turbine axis wear • Exhaust system clogged ― Diesel particulate filter clogged (damage, burnt out) ― Clogging caused by freezing • PCM malfunction

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the freeze frame data/snap shot data.	—	Go to the next step.
2	INSPECT EXHAUST GAS PRESSURE SENSOR NO.1 • Inspect exhaust gas pressure sensor No.1. (See EXHAUST GAS PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2].) • Is exhaust gas pressure sensor No.1 normal?	Yes	Go to the next step.
No	Replace exhaust gas pressure sensor No.1, then go to Step 8. (See EXHAUST GAS PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
3	INSPECT MAP SENSOR NO.2 • Inspect MAP sensor No.2. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-D 2.2].) • Is MAP sensor No.2 normal?	Yes	Go to the next step.
No	Replace MAP sensor No.2, then go to Step 8. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4	INSPECT COMPRESSOR BYPASS VALVE • Visually inspect the compressor bypass valve condition. • Is the compressor bypass valve disengaged?	Yes	Replace the turbocharger, then go to Step 8. (See TURBOCHARGER REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No	Go to the next step.
5	INSPECT SMALL-TYPE COMPRESSOR WHEEL • Open the compressor bypass valve and visually inspect the wheel condition from the intake air side. • Is the wheel deformed or damaged?	Yes	Replace the turbocharger, then go to Step 8. (See TURBOCHARGER REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No	Go to the next step.
6	INSPECT SMALL-TYPE TURBOCHARGER SHAFT AND BEARING • Open the compressor bypass valve and verify that the rotation of the compressor wheel is smooth using a long object (long rod) from the intake air side. Caution • Do not apply excessive load. Otherwise, the compressor wheel could be damaged. • Is the part normal?	Yes	Go to the next step.
No	Replace the turbocharger, then go to Step 8. (See TURBOCHARGER REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
7	INSPECT THE EXHAUST SYSTEM FOR CLOGGING • Remove the diesel particulate filter. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].) • Visually inspect the diesel particulate filter for condition. • Is there any malfunction?	Yes	Replace the catalytic converter, then go to the next step. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No	A temporary malfunction can be considered due to freezing of the exhaust system. Go to the next step.
8	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Reconnect all the disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Drive the vehicle on flat roads under the following conditions Warning • To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS). • Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. 1. Display PID MAP_DSD and MAP using the M-MDS. 2. Start the engine and warm it up. 3. Accelerate in 2nd gear to 40 km/h. 4. Accelerate in 2nd gear from 40 km/h to 55 km/h taking 5 s or more. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Has DTC P2262:00 been recorded?	Yes	Replace the vacuum pump, then go to the next step. (See VACUUM PUMP REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
9	VERIFY OTHER DTCs • Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SKYACTIV-D 2.2].)
No	DTC troubleshooting completed.
