Refer to «DTC CHECK / CLEAR»(ref-553305-S22976237422013051700000) . Turn the power off and wait for at least 30 seconds. Turn the power switch on (IG). Turn the Techstream on. Put the engine in inspection mode (maintenance mode). Refer to «INSPECTION MODE PROCEDURE»(ref-553290-S22500871302013051700000) . Start the engine and warm it up. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes. Read the DTCs. RESULT Result Proceed to DTC is not output A DTC P0171 or P0172 is output B B --> See step 27 A --> END
23. GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-553305-S14271064972013051700000)
24. REPLACE ENGINE COOLANT TEMPERATURE SENSOR. Refer to «REMOVAL»(ref-553431-S10081364622013051700000)

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Record the DTC(s) and freeze frame data.
5. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
6. Put the engine in inspection mode (maintenance mode). Refer to «INSPECTION MODE PROCEDURE»(ref-553290-S22500871302013051700000) .
7. Using the Techstream, switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE»(ref-553305-S15065568862013051700000) .
8. Read the misfire counts of each cylinder, Cylinder #1 Misfire Count to Cylinder #4 Misfire Count, with the engine idling. If any misfire count is displayed, skip the following confirmation driving pattern.
9. Drive the vehicle so that the vehicle conditions displayed in Misfire RPM and Misfire Load of the Data List are the same as the freeze frame data. Perform this step several times. HINT: In order to store misfire DTCs, it is necessary to operate the vehicle for the period of time shown in the table below, confirm the Misfire RPM and Misfire Load in the Data List. Engine speed Duration Idling 4.5 minutes or more 1000 4.5 minutes or more 2000 2.5 minutes or more 3000 1.5 minutes or more
10. Check whether misfires have occurred by checking DTCs and freeze frame data. HINT: Do not turn the power switch off until the output DTC(s) and freeze frame data have been recorded. When the ECM returns to normal mode (default), the stored DTC(s), freeze frame data and other data are cleared.
11. Record the DTC(s), freeze frame data and misfire counts.
12. Turn the power switch off and wait for at least 30 seconds.
13. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
